= gsl = == Description == Website: http://www.gnu.org/software/gsl/ From the website above: The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. The library provides a wide range of mathematical routines such as random number generators, special functions and least-squares fitting. There are over 1000 functions in total with an extensive test suite. If the variable SAGE_CHECK is exported to the value "yes" when building Sage, GSL's test suite is run. == License == * GPL V3 == SPKG Maintainers == * William Stein == Upstream Contact == * http://www.gnu.org/software/gsl/ GSL mailing lists: * Bug-gsl mailing list -- bug reports for the GNU Scientific Library should be sent to bug-gsl@gnu.org * Help-gsl users mailing list -- for questions about installation, how GSL works and how it is used, or general questions concerning GSL. * Info-gsl mailing list -- announcements of new releases are made there. == Dependencies == * None - GSL 1.15 does not depend on any other Sage package to compile, link and pass all of GSL's self-tests. Despite that fact, as of 20th May 2011, ATLAS is listed as a dependency in spkg/standard/deps. (It comes with its own CBLAS implementation that is e.g. used when running the GSL test suite during installation; however, the Sage library only uses it as a fall-back, if e.g. ATLAS's CBLAS library is not present.) == Special Update/Build Instructions == * Make sure the following patch still apply or remove it if integrated upstream. === Patches === * cygwin.patch: patch build system so that it builds a shared library on Cygwin. == Changelog == === gsl-1.15.p1 (Jean-Pierre Flori, 12 February 2013) === * #14096: let GSL build a shared library on Cygwin. === gsl-1.15.p0 (Simon King, 11th December 2011) === * #12131: Use --libdir, to make this package work on openSUSE === gsl-1.15 (David Kirkby, 20th May 2011) === * #11357 Update to the latest version of GSL from the one currently in Sage which was the previous version. This also fixes bug #10000, as the failure to build on AIX has been fixed (my own changes were accepted upstream). === gsl-1.14 (David Kirkby, 21st July 2010) === * #9533 Update GSL to the latest upstream release - the previous version (1.10) was nearly 3 years old. * Reformatted this file for 80 characters width. * Added 'exit 1' to spkg-install so the build terminates if 'configure' fails to run properly. * Same as above, when running 'make' * Same as above, when running 'make install' * Removed the option --enable-shared from the configure script, as the default is to make shared libraries (see src/INSTALL) * Removed all patches. I doubt they are useful when they are on a version of GSL that is nearly 3 years old. It is better to resolve problems if found, rather than try to use patches made against a very outdated version of GSL. The GSL test suite has passed all tests on systems running Cygwin, Linux, HP-UX (PA-RISC processor), OpenSolaris x64, OS X (x86) and Solaris (SPARC processor). * Used $MAKE for building, as building in parallel is reliable. * $MAKE is also used in spkg-check for testing GSL in parallel. The GSL has been tested on around 50 parallel builds in total on Linux, OpenSolaris, OS X and Solaris. Each time all the self-tests of GSL pass. From 2 to 1000 threads were used. * Removed reference to GPL 2 in earlier releases - it is irrelevant what licence previous releases of GSL were released under. * Removed notes about patches on OS X. GSL would appear to handle OS X properly. * Added the "Special Update/Build Instructions" section to SPKG.txt which was previously missing, though currently no special steps are required. * Added notes to SPKG.txt about an unnecessary ATLAS dependency in $SAGE_ROOT/spkg/standard/deps, and an explanation why GSL does *not* depend on ATLAS. * Force GSL to be built with no optimisation if SAGE_DEBUG is set to "yes" * Check that $SAGE_ROOT is defined both in spkg-install and spkg-check. * Exported LDFLAGS and CPPFLAGS when SAGE64 is set to "yes". This environment variable would be set to "yes" to create 64-bit binaries on platforms which default to 32-bit. These platforms include Solaris and OpenSolaris, some versions of OS X and at least versions of HP-UX. Exporting CPPFLAGS and LDFLAGS is unnecessary with the current version of GSL, but it may become necessary on later revisions, so it is safer to add this now. On platforms where the default it to create 64-bit binaries, there is no need to set SAGE64. * spkg-install and spkg-check now make use of the environment variable CFLAG64 which can be used to specify an alternate compiler flag to -m64 when building a 64-bit version of the library. === gsl-1.10.p2 (Jaap Spies, Jan 25th, 2010) === * Made SAGE64=yes work for Open Solaris 64 bit * Removed Michael as maintainer === gsl-1.10.p1 (Michael Abshoff, April 20th, 2008) === * always use GSL's isinf (fixes #2973) === gsl-1.10-p0 (Michael Abshoff, Jan. 26, 2008) === * fix 64 OSX build * fix spkg-check target * work around isinf bug on OSX === gsl-1.10 (Michael Abshoff, Jan. 25, 2008) === * update to gsl 1.10 * add .hgignore * write proper SPKG.txt === gsl-1.9 === * initial release == Build Notes == * None
