--- Comment #14 from coypu <coypu at sdf dot org> --- Also, after these two patches, my own build of arm--netbsdelf is failing from this: configure: error: Pthreads are required to build libgomp Looking at config.log, the error is actually: configure:15118: /tmp/build/./gcc/xgcc -B/tmp/build/./gcc/ -B/usr/local/arm--netbsdelf/bin/ -B/usr/local/arm--netbsdelf/lib/ -isystem /usr/local/arm--netbsdelf/include -isystem /usr/local/arm--netbsdelf/sys-include --sysroot=/home/fly/shark/destdir.shark/ -o conftest -g -O2 conftest.c -lpthread >&5 /home/fly/shark/destdir.shark/usr/lib/libpthread.so: undefined reference to `__modsi3@GCC_3.0' collect2: error: ld returned 1 exit status I'm not sure what is the cause of that.
