Fixes problem with breaking handwritten makefile and config generator that uses mkdir to test for OS (Windows/Linux) Also fixes other build problems with GCC-15 Correcting ebuild to work on musl system was unpleasant and it looks ugly. Such is life with horrible, hand-written makefile generator Closes: https://bugs.gentoo.org/886467 Closes: https://bugs.gentoo.org/898294 Closes: https://bugs.gentoo.org/832812 Closes: https://bugs.gentoo.org/898296 Signed-off-by: NHOrus <jy6x2b32pie9@yahoo.com> Closes: https://github.com/gentoo/gentoo/pull/40691 Signed-off-by: Sam James <sam@gentoo.org> sci-libs/taucs/Manifest | 1 + .../taucs/files/taucs-2.2-missing-include.patch | 36 +++++++ sci-libs/taucs/files/taucs-2.2.1-C23.patch | 120 +++++++++++++++++++++ .../taucs-2.2.1-allocate-memory-in-test.patch | 24 +++++ sci-libs/taucs/metadata.xml | 3 + sci-libs/taucs/taucs-2.2.1.ebuild | 84 +++++++++++++++ 6 files changed, 268 insertions(+)
