--- Comment #7 from ofv at wanadoo dot es ---
make BOOT_CFLAGS='-O1' V=1 all
make BOOT_CFLAGS='-O0' V=1
both fails the same way as the initial report.
export CFLAGS="-march=i686 -mtune=generic -O0 -pipe"
export CXXFLAGS="-march=i686 -mtune=generic -O0 -pipe"
make BOOT_CFLAGS='-O0' V=1
fails on
configure: error: unsupported system, cannot find sizeof (omp_lock_t)
make[2]: *** [Makefile:24035: configure-stage1-target-libgomp] Error 1
(this is before the build reaches the failure point discussed on this bug
report).
Finally, trying to reduce as much as possible the optimization passes:
export CFLAGS="-march=i686 -mtune=generic -Og -pipe"
export CXXFLAGS="-march=i686 -mtune=generic -Og -pipe"
make BOOT_CFLAGS='-Og' V=1
fails the same way as the initial report.
