The tarball for calc version 2.15.0.0 was missing version.h.
The version.h is now listed as part of the calc distribution.
Added a chk_tree tool to help look for problems such as files that are
result of building calc that are also part of the calc distribution,
and files that are part of the calc source that are missing from the
calc distribution, and files that are of unknown status that are either
result of building calc nor missing from the calc distribution.
Updated file lists in Makefile, sorting as needed.
Updated Makefile PHONY rule to include Makefile rules that are NOT files.
Reduced make chatter for rules that build lists.
Added make verifydist to verify the existence of files that are part of
the calc distribution.
Added make verifydist to make prep.
Added a chk_tree double check, one after make clobber, one before the
final make chk, to make prep.
Changed calc_errno a global int variable so that is may be directly
accessed by libcalc users.
Further improve help files for help/errno, help/error, help/newerror,
help/stoponerror and help/strerror by adding to documentation
of the calc error code system as well as libcalc interface
where applicable.
Changed #define E_USERDEF to #define E__USERDEF.
Removed use of E_USERDEF, E__BASE, E__COUNT, and E__HIGHEST
from custom/c_sysinfo because the c_sysinfo is just a demo
and this will simplify the custom/Makefile.
The include file calcerr.h is now the errsym.h include file.
The calcerr.tbl has been replaced by errtbl.c and errtbl.h.
The calcerr_c.awk, calcerr_c.sed, calcerr_h.awk, and
calcerr_h.sed files are now obsolete and have been removed.
The calcerr.c and calcerr.h now obsolete and are no longer built.
The calc computation error codes, symbols and messages are now in
a error_table[] array of struct errtbl.
An E_STRING is a string corresponds to an error code #define.
For example, the E_STRING for the calc error E_STRCAT,
is the string "E_STRING". An E_STRING must now match
the regular expression: "^E_[A-Z0-9_]+$".
The old array error_table[] of error message strings has been
replaced by a new error_table[] array of struct errtbl. The struct
errtbl array holds calc errnum error codes, the related E_STRING
symbol as a string, and the original related error message.
To add new computation error codes, add them near the bottom of the
error_table[] array, just before the NULL entry.
The ./errcode utility, when run, will verify the consistency of
the error_table[] array.
The Makefile uses ./errcode -e to generate the contents of
help/errorcodes file. The help errorcodes now prints
information from the new cstruct errtbl error_table[] array.
The help/errorcodes.hdr and help/errorcodes.sed files are
now obsolete and have been removed.
The Makefile uses ./errcode -d to generate the contents of the
errsym.h include file.
Updated .gitignore and trailblank to support the above changes.
Fixed more documentation and code comments that referred to the old
additive 55 (a55) shuffle pseudo-random number generator. We have
been using the subtractive 100 shuffle pseudo-random number generator
in place of the additive 55 generator for a while now.
Fix "Under source code control" date for new version.h file.
Sorted the order of symbols printed by "make env".
Test if <stdbool.h> exists and set HAVE_STDBOOL_H accordingly
in have_stdbool.h. Added HAVE_STDBOOL_H to allow one to force
this value.
Added "bool.h" include file to support use of boolean symbols,
true and false for pre-c99 C compilers. The "bool.h" include
file defines TRUE as true, FALSE as false, and BOOL as bool:
for backward compatibility.
The sign in a ZVALUE is now of type SIGN, whcih is either
SB32 when CALC2_COMPAT is defined, or a bool.
Replaced in C source, TRUE with true, FALSE with false, and
BOOL with bool.
Moved calc version definition from version.c to version.h.
Added CALC2_COMPAT, that when defined attempts to maintain calc
version 2 compatibility. When MAJOR_VER <= 2, CALC2_COMPAT is
defined. This is anticipation for a future calc version 3 code.
Under macOS, to reduce dependency chains, we remove functions
and data that are unreachable by the entry point or exported
symbols. In particular, the macOS linker is used with both
"-dead_strip" and "-dead_strip_dylibs".
The libcalc shared library is now linked with libcustcalc.
Sort .gitignore. Add calc.spec to .gitignore.
Update format of header part of Makefiles.
Modify calc.spec.in to handle dynamic shared libraries with 3-digit
version numbers.
Under macOS, to reduce dependency chains, we remove functions and
data that are unreachable by the entry point or exported symbols.
In particular, the linker is run with "-dead_strip" and with
"-dead_strip_dylibs".
Removed the ${CAL_PASSDOWN}, ${HELP_PASSDOWN}, ${HELP_PASSDOWN},
${CSCRIPT_PASSDOWN} Makefile variables as the new Makefile
include files keep Makefile variables in sync.
Fixed the ability of calc to compile when CUSTOM is undefined
(i.e., -UCUSTOM). The libcustcalc is always built, regardless
of the $(ALLOW_CUSTOM} Makefile variable. However when CUSTOM
is undefined, the bulk of custom functions are not defined.
Moved makefile variables that configure calc and configure how to
compile calc from Makefile into a new Makefile.config file.
The Makeifle includes the Makefile.config file.
The cal/Makeifle includes the Makefile.config file.
The cscript/Makeifle includes the Makefile.config file.
The custom/Makeifle includes the Makefile.config file.
The help/Makeifle includes the Makefile.config file.
Now, the Makefile.config file will consistently configure
calc and how calc is compiled and built by all calc Makefiles.
The platform target section from the old Makefile has been moved to
a new file, Makefile.target. The custom/Makefile no longer includes
Makefile.
The Makeifle includes the Makefile.target file.
The cal/Makeifle includes the Makefile.target file.
The cscript/Makeifle includes the Makefile.target file.
The custom/Makeifle includes the Makefile.target file.
The help/Makeifle includes the Makefile.target file.
Now, the Makefile.target file will consistently set
target information for all calc Makefiles.
The cal/Makeifle includes the Makefile.local file.
The cscript/Makeifle includes the Makefile.local file.
The custom/Makeifle includes the Makefile.local file.
The help/Makeifle includes the Makefile.local file.
Thus, one may modify or append many Makefile variables
in all calc Makefiles.
Dropped support of Makefile.simple and custom/Makefile.simple.
The calc version 2.14.3.0 is the last release that supported
the Makefile.simple and custom/Makefile.simple files.
Now, a make that supports makefile conditional syntax is required.
The platform target section from the old Makefile has been moved
to a new file, Makefile.target. The Makefile.target is shared
by both Makefile and custom/Makefile. The custom/Makefile no
longer includes Makefile (instead it includes ../Makefile.target).
Updated comments in Makefile.local for how to Diagnosing memory,
thread, and crash issues under RHEL and macOS.
We no longer support the Makefile variable ${ALLOW_CUSTOM} to be empty.
Normally ${ALLOW_CUSTOM} is:
ALLOW_CUSTOM= -DCUSTOM
Now, to disable custom disable custom even if -C is given, use:
ALLOW_CUSTOM="-UCUSTOM"
Added comments in Makefile.local for how to reduce dependency chains
under macOS. XXX - this doesn't yet work so don't uncomment - XXX.
The following are the changes in this release:
Updated COPYING to include the actual text of "The Unlicense".
Made minor formatting changes to the file.
The Darwin specific ${DARWIN_ARCH}, thay by default was unset,
is now the ${ARCH_CFLAGS} Makefile variable. Comments about
various "-arch name" have been moved to the ${ARCH_CFLAGS} area.
For old Apple Power PC systems, the following is added:
COMMON_CFLAGS+= -std=gnu99
COMMON_LDFLAGS+= -std=gnu99
ARCH_CFLAGS+= -arch ppc
Old Apple Power PC systems should be detected by the
"uname -p" command returning "powerpc". One may force the
Power PC mode by adding to the end of any make command:
make ...make_args... target=Darwin arch=powerpc
or by adding the following in the Makefile.local file:
target= Darwin
arch= powerpc
Improved the output of the calcinfo rule by adding echos
of various uname values as well as some top Makefile variables.
Fixed the BUGS file with respect to using `make debug`.
Added a final ls of `debug.out` for `make debug`.
The following are the changes in this release:
Added cal/fnv_tool.cal, a calc resource file defining:
find_fnv_prime(bits)
deprecated_fnv0(bits,fnv_prime,string)
fnv_offset_basis(bits,fnv_prime)
fnv1a_style_hash(bits,fnv_prime,prev_hash,string)
Fixed sorted order of cal/README.
The following are the changes in this release:
Ported calc to the s390x IBM Mainframe running RHEL9.1.
Added cal/splitbits.cal:
splitbits(x, b)
Given an integer x, split the value into a list of integers,
each of which is at most b bits long.
The value b must be an integer > 0.
The number of elements in the returned list is:
ceil((highbit(x) + 1) / b)
If x == 0, then a list of 1 element containing 0 is returned.
If x < 0, then the two's compliment of abs(x) is returned.
Even though calc represents negative integers as positive values
with sign bit, the bits returned by this function are as if
the integer converted as if the integer was a two's compliment value.

; help resource
The following are the changes in this release:
Fixed version numbers in two cases in CHANGES that referred
to the 2.14.2.x instead of 2.14.1.x.

correct internal function name of str2z().
Fixed obsolete references to the atoq() in LIBRARY to use the
correct internal function name of str2q().
Document in help/unexpected that * operator has has a higher
precedence than << in calc, which differs from C. Thanks
goes to GitHub user @inguin for pointing put this difference.

The following are the changes in this release:
Fixed missing <string.h include in have_fpos_pos.c.
Change calc version from 2.14.1.2 to 2.14.2.3 as part of a test to
build calc RPMs on a reference RHEL8.7 platform (formerly a RHEL7.9
platform).
The following are the changes in this release:
Restored use of the #define FPOS_POS_LEN symbol. This refers to
the length of the __pos element (if the __pos element exists),
the fpos_t type (if that type exists).
Changed SWAP_HALF_IN_FILEPOS(dest, src) mato to use FILEPOS_LEN Little
Endian when FILEPOS is a simple scalar type (i.e., HAVE_FILEPOS_SCALAR
is defined).
Changed #define HAVE_FPOS to HAVE_FGETSETPOS.
Corrected comment in have_fpos_pos.h. The HAVE_FPOS_POS symbol was
NOT related to fgetpos & fsetpos but rather if we we have an __pos
element in FILEPOS.
Changed #define HAVE_NO_FPOS to HAVE_NO_FGETSETPOS.
Improved comments in have_fpos_pos.h to show why and how
HAVE_FPOS_POS, FPOS_POS_BITS, and FPOS_POS_LEN were defined or undefed.
Changed showfiles builtin to print sizes cast to (long int) with
the "%ld" printf format to avoid implementations that do not support
the "%lld" printf format specifier.
Renamed have_fpos.h to have_fgetsetpos.h. Renamed CALC_HAVE_FPOS_H
to CALC_HAVE_FGETSETPOS_H. The make install and the olduninstall
rules remove the any old have_fpos.h that was previously installed.
Added swap_HALFs(dest, src, len) function to byteswap.c.
Calc can now handle Big Engian file position sizes that are a
multiple of BASEB bits in length. Before handle Big Engian file
positions could only be 32 and 64 bits in length. This will allow,
for example, a Big Engian file position size of 128 (assuming that
128/BASEB is is an integer).
Temporary workaround for musl libc systems such as gentoo Linux that
allows them to compile calc and successfully run the regression test.
The following are the changes in this release:
Added a few remarks on calc version numbers to version.c.
Fixed how fposval.h is built. On a number of systems, the fposval.c
file failed to compile incorrectly. This caused problems for systems in
which fposval.h.def was not correct.
Fixed how have_memmv.h is built. On a number of systems, the have_memmv.c
file failed to compile incorrectly, producing a potentially incorrect
have_memmv.h file for such systems.
Fixed how align32.h is built. On a number of systems, the align32.c
file failed to compile incorrectly, producing a potentially incorrect
align32.h file for such systems.
Fixed how have_newstr.h is built. On a number of systems, the have_newstr.c
failed to compile incorrectly, producing a potentially incorrect
have_newstr.h file for such systems.
Fixed how have_strdup.h is built. On a number of systems, the have_strdup.c
file failed to compile incorrectly, producing a potentially incorrect
have_strdup.h file for such systems.
Fixed how have_strlcat.h is built. On a number of systems, the have_strlcat.c
file failed to compile incorrectly, producing a potentially incorrect
have_strlcat.h file for such systems.
Fixed how have_strlcpy.h is built. On a number of systems, the have_strlcpy.c
file failed to compile incorrectly, producing a potentially incorrect
have_strlcpy.h file for such systems.
Fixed how have_uid_t.h is built. On a number of systems, the have_uid_t.c
file failed to compile incorrectly, producing a potentially incorrect
have_uid_t.h file for such systems.
Fixed how have_uid_t.h is built. On a number of systems, the have_uid_t.c
file failed to compile incorrectly, producing a potentially incorrect
have_uid_t.h file for such systems.
The following are the changes from calc version 2.14.1.0 to date:
Fixed alignment of show item section of help command.
Bug fix: While 0^0 == 1, now for y > 0, 0^y == 0.
Adjusted cal/test8900.cal to reflect this bug fix.
Added tests to cal/regress.cal to help verify bug fix is fixed.
Changed /*NOTREACHED*/ to not_reached(); and use "attribute.h".
Added .PHONY rule, just after all rule, to Makefiles.
Fixed an improper indentation issue.
The following are the changes in this release:
Fixed typo in Makefile.local comment.
Established a tagging procedure for a production release.
Production git tags will be of the form:
prod-2.x.y.z
We apologize for the calc v2.14.0.12 source tarball that was missing
critical files. While the executable was well tested, our release
process was deficient.
We are improved our release process and added tests during the release
procedure to help verify that we are not regressing in to the "v2.14.0.12
source tarball" issue, among other things.
Depending on how things do, you might is several releases come out over
a short period of time. The core of calc isn't changing, so the calc
executable will be the same as we focus on the Makefiles, our release
procedure, and related documentation / help files.
=-=
The following are the changes in this release:
Minor tweak to seed() builtin. Updated help/srand and help/srandom.
Moved Makefile.ship into Makefile.
Removed custom/Makefile.head and custom/Makefile.tail.
The custom/Makefile is now part of source and includes Makefile.
In particular, custom/Makefile makes use of the 'middle' of
the new top level Makefile where calc's top level Makefile
variables are defined.
Makefile.simple and custom/Makefile.simple are now part of the source
and are constructed from Makefile and custom/Makefile respectively.
The Makefile.simple and custom/Makefile.simple avoid using GNU
conditionals. They may be used with older/classic make commands.
Makefile.local will include comments about how to better use
it. Between releases, Makefile.local at the top of the master branch
will contain how we typically build calc and test calc (FYI: we
normally enable things such as -Werror -Wextra -pedantic). When we
push out a release, Makefile.local will be stripped of non-comment
lines. Thus, releases of calc, and, released "calc*.src.rpm"
files and the source tarballs, will have a Makefile.local with
only comments.
The "README.*" files and "HOWTO.INSTALL" file have been updated.
By default, compiler warnings have been turned up. The Makefile
variable ${CCWARN} now defaults to:
CCWARN= -Wall -Wextra -pedantic
The previous level of compiler warnings can be easily restored by
adding to Makefile.local:
CCWARN:= -Wall
The readline, history and ncurses libraries are now default.
The Makefile variables ${USE_READLINE}, ${READLINE_LIB}, and
${READLINE_EXTRAS} now default to:
USE_READLINE= -DUSE_READLINE
READLINE_LIB= -lreadline
READLINE_EXTRAS= -lhistory -lncurses
The previous mode where readline, history and ncurses libraries
were not compiled in by default can be easily restored by
adding to Makefile.local:
USE_READLINE:=
READLINE_LIB:=
READLINE_EXTRAS:=
We have renamed "stable" as "production".
We have renamed "unstable" as "tested".
On the web site:
http://www.isthe.com/chongo/src/calc/
these files has been renamed:
2.x.y.z_IS_LATEST_STABLE ==> 2.x.y.z_IS_LATEST_PRODUCTION
2.x.y.z_IS_LATEST_UNSTABLE ==> 2.x.y.z_IS_LATEST_TESTED
The terms 'stable' and 'unstable' were both misleading and
inaccurate. For details see the new documention file:
README.RELEASE
See also the help command:
; help release
Fixed bug impacting how have_ustat.h was formed.
Updated help/archive to reflect GitHub use.
We apologize for the calc v2.14.0.12 source tarball that was missing
critical files. While the executable was well tested, our release
process was deficient.
We are improved our release process and added tests during the release

Depending on how things do, you might is several releases come out over
a short period of time. The core of calc isn't changing, so the calc
executable will be the same as we focus on the Makefiles, our release
procedure, and related documentation / help files.
We made several changes to the Makefiles. We also added a new
README.RELEASE document (see "help release") that is a work in
progress. Along the way we discovered a few things that needed to be
updated in documentation.
See the CHANGES file for details.
The following are the changes in this release:
Fixed a number of typos.
Drop support for SunOS, IRIX and MINGW32_NT-5.0 targets.
Drop support for CLOCK_SGI_CYCLE. Drop testing for __MSDOS__.
Minor improvement of various help files. Made format of help
files more consistent.
Corrected a few comments in zrandom.c, including a case where
the comment referred to 1007 when it should have used 2^32.
Improved seed() generation. Improved some comments in seed.c.
Added have_environ.c to build have_environ.h in order to
determine if:
extern char **environ; /* user environment */
is an valid external symbol.
Fixed documentation that referred to the old additive 55
generator. We have been using the subtractive 100 in place
of the additive 55 generator for a while now.
Fixed depend rule for custom/Makefile.
Fixed how Makefile variable SHELL is set on macOS vs. Linux.
Using /bin/sh on macOS due to how zsh treats globs by default.
Added charbit.h to define CALC_CHARBIT which is either CHAR_BIT
from <limits.h> or 8 or a value set by the Makefile variable
CALC_CHARBIT. Added have_limits.h to determine if <limits.h>
is a system include file.
Compiling now tests for _WIN64 as well when testing for _WIN32.
Now assuming that <stdio.h> is available under _WIN32 and _WIN64.
Added some preliminary notes about attempts to compile calc
under Windows 11.
BTW: While we are unable to use Windows 11, we welcome
Windows 11 developers to try compiling calc natively
(instead of via a Linux virtual machine). If you are
able to compile Windows 11 natively, we would welcome
GitHub pull requests showing any needed modifications:
https://github.com/lcn2/calc/pulls
Please also add notes to the 'Compiling calc under Windows 11'
section in README.WINDOWS file.
We added Makefile.simple as part of the master branch source
to help those who may be using a make tool that does not support
GNU Make-like features such as "ifeq" and ":=".
Fixed incorrect ustat_dev member ref in seed() builtin that
was part of the unreleased calc v2.12.0.11.
