Special Update/Build Instructions¶

As some patches touch config/acinclude.m4, we have to touch aclocal.m4, configure, Makefile.in and gf2x/gf2x-config.h.in to prevent autotools to try to regenerate these files.

Patches¶

0001-Trac-15014-Let-gf2x-build-a-shared-library-on-Cygwin.patch: pass -no-undefined flag to libtool.
0002-tr-portability.patch: backport upstream fix for non-portable tr use
0003-Improve-detection-of-sse2-support.patch: backport upstream improved check for sse2
0004-Add-disable-hardware-specific-code.patch: add option -disable-hardware-specific-code to build system. This is partly backported from upstream.
0005-Update-autotooled-files.patch: the above patches make changes to code used by autotools for generation of the build system. This patches those files, so that autotools need not be installed.
0006-Fix_make_check_not_failing_on_errors.patch: (upstream patch) Fix bug in shell script such that ‘make check’ always fails upon errors.
