FWIW, I still get a problem, this: /bin/sh ./libtool --tag CC --mode=link /usr/local/src/trunk/objdir/./gcc/xgcc -B/usr/local/src/trunk/objdir/./gcc/ -B/usr/local/gnu/i686-pc-cygwin/bin/ -B/usr/local/gnu/i686-pc-cygwin/lib/ -isystem /usr/local/gnu/i686-pc-cygwin/include -isystem /usr/local/gnu/i686-pc-cygwin/sys-include -Wall -Werror -Wc,-pthread -g -O2 -Wl,-O1 -o libgomp.la -version-info 1:0:0 -no-undefined -bindir "/usr/local/gnu/bin" -rpath /usr/local/gnu/lib/gcc/i686-pc-cygwin/4.5.0 alloc.lo barrier.lo critical.lo env.lo error.lo iter.lo iter_ull.lo loop.lo loop_ull.lo ordered.lo parallel.lo sections.lo single.lo task.lo team.lo work.lo lock.lo mutex.lo proc.lo sem.lo bar.lo ptrlock.lo time.lo fortran.lo affinity.lo libtool: link: /usr/local/src/trunk/objdir/./gcc/xgcc -B/usr/local/src/trunk/objdir/./gcc/ -B/usr/local/gnu/i686-pc-cygwin/bin/ -B/usr/local/gnu/i686-pc-cygwin/lib/ -isystem /usr/local/gnu/i686-pc-cygwin/include -isystem /usr/local/gnu/i686-pc-cygwin/sys-include -shared .libs/alloc.o .libs/barrier.o .libs/critical.o .libs/env.o .libs/error.o .libs/iter.o .libs/iter_ull.o .libs/loop.o .libs/loop_ull.o .libs/ordered.o .libs/parallel.o .libs/sections.o .libs/single.o .libs/task.o .libs/team.o .libs/work.o .libs/lock.o .libs/mutex.o .libs/proc.o .libs/sem.o .libs/bar.o .libs/ptrlock.o .libs/time.o .libs/fortran.o .libs/affinity.o -pthread -Wl,-O1 -o .libs/libgomp-1.dll -Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker .libs/libgomp-1.dll xgcc: unrecognized option '-pthread' Creating library file: .libs/libgomp-1.dll libtool: link: (cd ".libs" && rm -f "libgomp.lib" && ln -s "libgomp-1.dll" "libgomp.lib") libtool: link: ar rc .libs/libgomp.lib alloc.o barrier.o critical.o env.o error.o iter.o iter_ull.o loop.o loop_ull.o ordered.o parallel.o sections.o single.o task.o team.o work.o lock.o mutex.o proc.o sem.o bar.o ptrlock.o time.o fortran.o affinity.o ar: .libs/libgomp.lib: File format not recognized make[5]: *** [libgomp.la] Error 1 make[5]: Leaving directory `/usr/local/src/trunk/objdir/i686-pc-cygwin/libgomp' make[4]: *** [all-recursive] Error 1 make[4]: Leaving directory `/usr/local/src/trunk/objdir/i686-pc-cygwin/libgomp' make[3]: *** [all] Error 2 make[3]: Leaving directory `/usr/local/src/trunk/objdir/i686-pc-cygwin/libgomp' make[2]: *** [all-stage1-target-libgomp] Error 2 make[2]: Leaving directory `/usr/local/src/trunk/objdir' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/usr/local/src/trunk/objdir' make: *** [all] Error 2 (and, yes, I've been building with libgomp for quite a while on cygwin, and, yes, I do remember the pthread warning showing up before, mentioned it to Dave, and it hadn't caused me problems before to my understanding) -- Cheers, /ChJ
