Added new aversin(x, [,eps]) for inverse versed sine and acoversin(x, [,eps])
for inverse coversed sine.
Improved trig function help files to reference use of complex arguments
that while supported were not documented.
Removed old Makefile testing rules for make dbx and make gdb.
Improved "make run" to execute calccalc using shared libraries
from the local directory, and with reading of the startup scripts
disabled.
Changed "make prep" to perform various tests that are used to
help verify that calc is ready for a release.
Added Makefile testing rule testfuncsort to check for the sort
of the builtin function list. Changed the order that builtin
functions are listed by "show builtin" and the help/builtin to
match the sorting of "LANG=C LC_ALL=C sort -d -u".
Added int.h as a centeral place for calc integer types and integer macros.
Currently zmath.c includes int.h but does not yet use it.
Added missing ptr type checks to chk_c.c.
The make chk_c file also forms status.chk_c.h which either
defines CHK_C when the C compiler and select include files
appear to meet calc requirements, or undefines CHK_C
when it does not.
Fixed have_statfs optional executable file extension ${EXT{ in
the ${UTIL_PROGS} make variable.
Prevented the "fake boolean value" when <stdbool.h> is missing,
from complicating C compilers post c17 standard.
Test if <stdint.h> exists and set HAVE_STDINT_H accordingly
in have_stdint.h. Added HAVE_STDINT_H to allow one to force
this value.
Test if <inttypes.h> exists and set HAVE_INTTYPES_H accordingly
in have_inttypes.h. Added HAVE_INTTYPES_H to allow one to force
this value.
Added c_chk.c to check the compiler and C include for calc
requirements. If you are unable to compile this program, or
if this program when compiles does not exit 0, then your C
compiler and/or C include fails to meet calc requirements.
Compilers that are at least c99 MUST be able to compile this
program such that when run will exit 0.
The "make hsrc" file will attempt to compile and run c_chk and
will warn if the C compiler and/or C include fails to meet
calc requirements. The "make debug" system will run c_chk -c
to print information about the C compiler and C include.
Currently failure to compile cc_chk.c or c_chk exiting non-0
will just print "WARNING!!" strings to stderr.
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.
Support for win32 and DJGPP has been dropped. Calc version
2.14.3.5 was the last to make references to win32 and make
references to DJGPP. Future versions of calc may work under
those systems, we just elected to remove the somewhat out of
date and awkward `win32.mkdef` and related win32 references.
If you are a win32 user, please feel free to create a win32
target in Makefile.target and submit as a pull request.
If you are a DJGPP user, please feel free to create a DJGPP
target in Makefile.target and submit as a pull request.
Until someone can test such systems, we prefer to wait
until someone is able to test and supply a pull request.
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 macOS linker is used with "-dead_strip" by default.
While calc on macOS will execute if linker used with "-dead_strip_dylibs"
and CUSTOM is defined, other applications that use libcalc but not
libcustcalc (such as sample_many and sample_rand) will fail to execute
due to missile symbols. Therefore "-dead_strip_dylibs" is not used
by default when ALLOW_CUSTOM is "-DCUSTOM" under macOS.
Thanks to GitHub user @TurtleWilly for bringing to our attention,
problems related to use of "-dead_strip_dylibs".
When installing shared libraries, libcalc.x.y.z will be a link
to the libcalc shared library and libcustcalc.x.y.z will be a link
to the libcustcal shared library.
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.
Improved .gitignore to ignore .static, calc-static,
sample_many-static and sample_rand-static.
Improved error messages when trying to compile with
with one calc type (when BLD_TYPE=calc-dynamic-only or
BLD_TYPE=calc-static-only) and install with the other.
When installing with BLD_TYPE=calc-static-only, the
installed calc and calc-static are links to each other.
Thanks to GitHub user @urtleWilly for this suggestion.
The dynamic shared libraries are not installed if they are not
built. So when installing with BLD_TYPE=calc-static-only, the
install rule will not attempt to install dynamic shared libraries.
Thanks to GitHub user @urtleWilly for bringing to our attention,
problems related to building a statically linked calc under macOS.
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`.
Test if the arch value (`uname -p`) is "powerpc".
PowerPC based systems no longer try to use xcrun to determine where
things like INCDIR (include files) are located.
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.
See also the help command:
; 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.
Rename MINGW Makefile variable (a holdover from MINGW32_NT-5.0)
to OSNAME.
Fixed FUNCPTR typedef in hist.c to fix deprecated compiler warnings.
Fixed when USE_READLINE, READLINE_LIB, READLINE_EXTRAS, and
READLINE_INCLUDE are set to empty (disable use of the GNU-readline
facility).
Fix cases of spaces before tabs in Makefile and Makefile.simple.
Fixed obsolete references to the atoz() in LIBRARY to use the
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).
Otherwise, the probe result changes with compilers which do not
support implicit function declarations, a language feature that
was removed from C in 1999.
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.
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.
Added full_debug rule to Makefile. This does the work of the
old debug rule in a more verbose mode by using Q= H=@ S= E= V=@.
The debug rule in the Makefile now pre-removes debug.out and then
runs make full_debug sending stdout and stderr to debug.out. It then
prints a few instructions about filing a GitHub issue bug report.
