It seems that the configure script in CVS does not check the CFLAGS environment variable at all. Indeed, on line 121 of configure.in, CFLAGS is explicitly set to be blank. Is this done for a reason? I see that several sets of CFLAGS are passed into the Makefiles by configure based upon specific architecture/compiler combinations -- perhaps this is the reason...? I ask because users may wish to

I am attaching a patch to R-0.63's configure.in file which will enable R to detect and use some special math libraries on linuxppc and mklinux. The patch provides tests for these libraries and enable/disable switches for them as well. One library is the libmoto math library which must be used in conjunction with libm (it only replaces some of libm's functions). The other is a RISC

This commit starts to split our massive, monolithic configure.ac file into smaller files, using the m4_include mechanism to combine them. I don't know if we should really do this, so I'm open to comments about it. However: - Our configure.ac script is 1800+ lines long, and that's pretty long. - configure.ac lacks structure; splitting it up might improve that. - From what I read,

From: Jyri Sarha <jsarha at ti.com> I optimized Speex resampler for NEON capable ARM CPUs. The first patch should speed up resampling on any platform that can spare the increased memory usage. It would be nice to have these merged to the master branch. Please let me know if there is anything I can do to help the the merge. The patches have been rebased on top of master branch in

Hi, This patchet allows a few targets to be disabled when unrequired. The rational is coming from VLC's contrib buildsystem, so far we use make -C to select only some subparts of the available targets. It would be easier and cleaner to use autoconf to do so IMHO. There's an additional patch which fixes the build when building for WinRT/UWP platform, upstreamed from VLC. We have a couple

These three patches ought to fix configure script detection of Ruby, especially on Debian where the Ruby C extensions library can be something like '-lruby1.8'. Rich.
