mjpegtools well not compile with hardened-gcc enabled. But it will work when you disabled hardened-gcc Reproducible: Always Steps to Reproduce: 1. emerge hardened-gcc 2. emerge mjpeg 3. Actual Results: gcc -DHAVE_CONFIG_H -I. -I. -I.. -I.. -mcpu=i686 -march=i686 -march=i686 -Wall -Wunused -c `test -f 'cpu_accel.c' || echo './'`cpu_accel.c cpu_accel.c: In function `x86_accel': cpu_accel.c:87: can't find a register in class `BREG' while reloading `asm' cpu_accel.c:104: can't find a register in class `BREG' while reloading `asm' cpu_accel.c:110: can't find a register in class `BREG' while reloading `asm' cpu_accel.c:132: can't find a register in class `BREG' while reloading `asm' cpu_accel.c:136: can't find a register in class `BREG' while reloading `asm' make[3]: *** [cpu_accel.o] Error 1 make[3]: Leaving directory `/dev/shm/portage/mjpegtools-1.6.1.90/work/mjpegtools-1.6.1.90/utils' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/dev/shm/portage/mjpegtools-1.6.1.90/work/mjpegtools-1.6.1.90/utils' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/dev/shm/portage/mjpegtools-1.6.1.90/work/mjpegtools-1.6.1.90' make: *** [all] Error 2 !!! ERROR: media-video/mjpegtools-1.6.1.90 failed. !!! Function src_compile, Line 52, Exitcode 2 !!! compile problem Expected Results: Hardened gcc should automatically stop using propolice and etdyn when compiling mjpegtools so it will compile
same result with gcc-3.3.1-r1

pappy When doing these types of changes it may also be worth while fixing it for others that desire pic code as well. inherit flag-o-matic filter-flags -fPIC
