Notes for the MPFR developers and CVS users
===========================================
To compile source code obtained from CVS, you need some GNU development
utilities: aclocal, autoheader, automake, autoconf. As some files like
"configure" are not part of the CVS repository, you first need to run
the "prepare" script; you can give the same options as you would give
to "configure" (give "--help" if you don't know).
To generate mpfr.info, you need texinfo version 4.2 (or higher).
The VERSION file contains the number of the next release version, i.e.
the version currently developed. If nightly snapshots are built, the
date in the yyyymmdd format must be added to the version number, for
instance: "2.0.1-20020319".
When submitting patches, unified diffs (option -u) are recommended,
as they are more readable. You can also use the option -d to generate
a smaller set of changes. See diff(1) for more information.
Though the ISO C standard requires that <stdlib.h> defines NULL,
do not use NULL with #include <stdlib.h> only, because this will
not work with the native SunOS 4 C compiler, whose headers are
not conform to the standard (even with C90); other problems may
occur on this architecture.
To make a release (for the MPFR team):
1) Check the version and update the date in mpfr.texi.
2) Update the ChangeLog file (using a recent version of rcs2log,
directly or with emacs), e.g. rcs2log > ChangeLog.2 and edit
ChangeLog to insert ChangeLog.2 at the beginning and remove
the duplicated lines.
3) Generate the release version with "make dist".
4) Test the release version on different machines, with and without
the --disable-alloca configure option.
5) If there is no problem, add a tag to the CVS corresponding to the
release, e.g. mpfr-2-0-1-rel for mpfr 2.0.1 (note that the periods
are replaced by dashes): cvs tag mpfr-2-0-1-rel
6) Update the VERSION file to indicate the next version.
Update the version in mpfr.texi.
