First, try lowering your CFLAGS. Second, try another gcc version. Third, try another (more stable?) glibc. I bet it's one of those three. I'm not sure, but breaking on ctype.h doesn't sound like an ffmpeg problem to me. Isn't stuff like prex glibc snapshots supposed to be p.masked, should this be exposed to every ~x86 runnning individual out there? ~ is for testing ebuilds, not packages.
it's not a glibc bug, it's a kernel headers bug it fails with 2.6.x headers but works with 2.4.23
Are you using 2.6.0 headers reporter ?
Yes, i'm using latest linux-headers: amd@Decoder linux-headers $ qpkg -I -v linux-headers sys-kernel/linux-headers-2.6.0 * sys-kernel/linux-headers-2.4.19-r1 * amd@Decoder linux-headers $ qpkg -f -v /usr/include/ctype.h sys-libs/glibc-2.3.3_pre20031222 *
@ reporter : well those are masked -* , so it's really up to you to fix this or just use the stable version. You aren't supposed to have more than one version of kernel-headers around btw i think. Someone in #gstreamer said that it got fixed in debian, i believe the link provides the info needed on that particular fix. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=218482&archive=yes I'm not sure if it's a bug in ffmpeg or the headers, i think that is more something for the kernel team to decide. reassigning to kernel team
This was fixed, grab the latest 2.6 linux-headers, merge them and gst-plugins should compile without problems. If you still get this, this is definitely not a linux-headers problem.
After re-emerging linux-headers-2.6.0, it worked.
Fixed.
