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.

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.
Changed Makefile to set shell before setting the SHELL Makefile
variable.
Added text to HOWTO.INSTALL to help people with systems that
lack the readline package.
Trimmed long line in the CONTRIBUTING.md file.
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
procedure to help verify that we are not regressing in to the "v2.14.0.12

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.
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.
Unfortunately due to the complex dependency issues between
Makefile, Makefile.ship and custom/Makefile, parallel GNU make
is NOT recommended. Sorry (tm Canada) :)
Replaced /usr/local with the use of ${PREFIX} in calc Makefiles.
The ${PREFIX} is not the same as ${T}. The ${T} specifies
a top level directory under which calc installs things.
While usally ${T} is empty, it can be specific path
as if calc where "chrooted" during an install.
The ${PREFIX} value, during install, is a path between
the top level ${T} install directory and the object
such as an include file.
Corrected a few more typos in Makefile comments.
Added a bunch of information to the near bottom of HOWTO.INSTALL
on calc Makefiles. This information discusses the various
Makefiles found in the calc source.
Added comments in various calc Makefiles about their origin.
In particular, for Makefiles that are constructed such as
Makefile.simple, custom/Makefile and custom/Makefile.simple
there are comments about how they were made.
For all calc Makefiles, including those in sub-directories,
near the top there is now a line of the form:
# SRC: ... some message about the origin ...
Added notes to help/unexpected about:
display() will limit the number of digits printed after decimal point
%d will format after the decimal point for non-integer numeric values
%x will format as fractions for non-integer numeric values
fprintf(fd, "%d\n", huge_value) may need fflush(fd) to finish
Fixed Makefile dependencies for the args.h rule.
Fixed Makefile cases where echo with -n is used. On some systems,
/bin/sh does not use -n, so we must call /bin/echo -n instead
via the ${ECHON} Makefile variable.
Add missing standard tools to sub-Makefiles to make them
easier to invoke directly.
Sort lists of standard tool Makefile variables and remove duplicates.
Declare the SHELL at the top of Makefiles.
Fixed the depend rule in the custom Makefile.
Improved the messages produced by the depend in the Makefiles.
Changed the UNUSED define in have_unused.h to be a macro with
a parameter. Changed all use of UNUSED in *.c to be UNUSED(x).
Removed need for HAVE_UNUSED in building the have_unused.h file.
CCBAN is given to ${CC} in order to control if banned.h is in effect.
The banned.h attempts to ban the use of certain dangerous functions
that, if improperly used, could compromise the computational integrity
if calculations.
In the case of calc, we are motivated in part by the desire for calc
to correctly calculate: even during extremely long calculations.
If UNBAN is NOT defined, then calling certain functions
will result in a call to a non-existent function (link error).
While we do NOT encourage defining UNBAN, there may be
a system / compiler environment where re-defining a
function may lead to a fatal compiler complication.
If that happens, consider compiling as:
make clobber all chk CCBAN=-DUNBAN
as see if this is a work-a-round.
If YOU discover a need for the -DUNBAN work-a-round, PLEASE tell us!
Please send us a bug report. See the file:
BUGS
or the URL:
http://www.isthe.com/chongo/tech/comp/calc/calc-bugrept.html
for how to send us such a bug report.
Added the building of have_ban_pragma.h, which will determine
if "#pragma GCC poison func_name" is supported. If it is not,
or of HAVE_PRAGMA_GCC_POSION=-DHAVE_NO_PRAGMA_GCC_POSION, then
banned.h will have no effect.
Fixed building of the have_getpgid.h file.
Fixed building of the have_getprid.h file.
Fixed building of the have_getsid.h file.
Fixed building of the have_gettime.h file.
Fixed building of the have_strdup.h file.
Fixed building of the have_ustat.h file.
Fixed building of the have_rusage.h file.
Added HAVE_NO_STRLCPY to control if we want to test if
the system has a strlcpy() function. This in turn produces
the have_strlcpy.h file wherein the symbol HAVE_STRLCPY will
be defined, or not depending if the system comes with a
strlcpy() function.
If the system does not have a strlcpy() function, we
compile our own strlcpy() function. See strl.c for details.
Added HAVE_NO_STRLCAT to control if we want to test if
the system has a strlcat() function. This in turn produces
the have_strlcat.h file wherein the symbol HAVE_STRLCAT will
be defined, or not depending if the system comes with a
strlcat() function.
If the system does not have a strlcat() function, we
compile our own strlcat() function. See strl.c for details.
Fixed places were <string.h>, using #ifdef HAVE_STRING_H
for legacy systems that do not have that include file.
Added ${H} Makefile symbol to control the announcement
of forming and having formed hsrc related files. By default
H=@ (announce hsrc file formation) vs. H=@: to silence hsrc
related file formation.
Explicitly turn off quiet mode (set Makefile variable ${Q} to
be empty) when building rpms.
Improved and fixed the hsrc build process.
Forming rpms is performed in verbose mode to assist debugging
to the rpm build process.
Compile custom code, if needed, after main code is compiled.
Fixed Makefile dependenies for the args.h rule.
Fixed Makefile cases where echo with -n is used. On some systems,
/bin/sh does not use -n, so we must call /bin/echo -n instead
via the ${ECHON} Makefile variable.
Add missing standard tools to sub-Makefiles to make them
easier to invoke directly.
Sort lists of standard tool Makefile variables and remove duplicates.
Declare the SHELL at the top of Makefiles.
Fixed the depend rule in the custom Makefile.
Fixed a mistake in "help intro" where some inserted text
changed the value of "." and thus made the next result
incorrect.
Clarified in "help factor" that 1 is returned if no
factor below the limit was found.
Removed Makefile variable ${MAKEFILE_REV}.
The missing cscript/square.calc file has been restored.
Fixed compiler errors and warnings related to GCC.
In particular, gcc/9.3.1 and gcc/10.2.1 now compile
calc without any compiler errors or warnings,
even with -Werror -Wextra -pedantic.
To print out information about the calc compliation
environment, we added the following make rule:
make calcinfo
Improved how 'make debug' operates.
Moved help/contrib to CONTRIB-CODE. The help/contrib file
is now build from a copy of CONTRIB-CODE.
Created a new calc bug report Email address. Created a new calc
question Email address. Created a new calc contribution Email
address. See the BUGS file for details.
Added "help questions" to print the QUESIONS help file.
If the environment variable $CALCHELP is defined and is non-empty,
then calc help files will be in the direcgory by the $CALCHISTFILE
environment variable.
If the environment variable $CALCCUSTOMHELP is defined and is
non-empty, then custom calc help files will be in the direcgory
by the $CALCCUSTOMHELP environment variable.
The calc-tester mailing list has been retired. See:

We are not ready, just yet, to enable:
-fsanitize=undefined -fsanitize=address
Instead we need to test with:
make clobber all check COMMON_ADD='-fsanitize=undefined -fsanitize=address'
Once the regression test passes, we can consider how to use COMMON_ADD
during development.
Added the makefile variable ${COMMON_ADD} that will add flags
to all compile and link commands. The ${COMMON_ADD} flags are
appended to both ${COMMON_CFLAGS} and ${COMMON_LDFLAGS}. This
facility is available to nearly all platforms except those with
very old make comamnds that do not understand the += operator.
Example on masOS (Darwin), one may invoke clang's -fsanitize
facility by:
make clobber all COMMON_ADD='-fsanitize=undefined -fsanitize=address'
Another example. To force C warnings to be treated as errors:
make COMMON_ADD='-Werror'
Some folks might think: “you still use RCS”?!? And we will say,
hey, at least we switched from SCCS to RCS back in … I think it was
around 1994 ... at least we are keeping up! :-) :-) :-)
Logs say that SCCS version 18 became RCS version 19 on 1994 March 18.
RCS served us well. But now it is time to move on. And so we are
switching to git.
Calc releases produce a lot of file changes. In the 125 releases
of calc since 1996, when I started managing calc releases, there
have been 15473 file mods!
calc GitHub philosophy
All of the previous commits in the master branch are the consists
of compressed source tarballs. The 125 git tags represent calc
releases from version 2.10.2t30 (Sat Jul 06 1996 04:17:00 GMT-0700)
to version 2.12.5.6 (Sun May 21 2017 15:03:29 GMT-0700).
At this point master branch will switch from those released tarballs
to the development tree. While we will make an effort to verify
that commits won't break calc: sometimes we will end up breaking
calc. You should consider the top of the master branch as potentially
unstable.
When we are ready to release calc, we will tag the commit with the
calc version and submit a release on GitHub. The GitHub release
will contain the usual RPMs, SRPMs, a release README and a released
source tarball.
