Hi,
I remember from a long time ago that we fixed this in the beginnings of GCC
posix threading, but it popped up again when I was working on a fresh set
of build scripts to replace the old cruft I wrote and used for a couple of
years.
Basic steps is this:
1. headers+binutils
2. GCC C (no libgcc), --enable-threads=posix
3. CRT
4. winpthreads -> fails:
libtool: link: i686-w64-mingw32-gcc -shared
src/.libs/libwinpthread_la-barrier.o src/.libs/libwinpthread_la-cond.o
src/.libs/libwinpthread_la-misc.o src/.libs/libwinpthread_la-mutex.o
src/.libs/libwinpthread_la-rwlock.o src/.libs/libwinpthread_la-spinlock.o
src/.libs/libwinpthread_la-thread.o src/.libs/libwinpthread_la-ref.o
src/.libs/libwinpthread_la-sem.o src/.libs/libwinpthread_la-sched.o
src/.libs/libwinpthread_la-clock.o src/.libs/libwinpthread_la-nanosleep.o
src/.libs/version.o -L./fakelib -O2 -o .libs/libwinpthread-1.dll
-Wl,--enable-auto-image-base -Xlinker --out-implib -Xlinker
.libs/libwinpthread.dll.a
/home/ruben/cross/build/x86_64-unknown-linux-gnu/mingw32/mingw32/lib/gcc/i686-w64-mingw32/4.8.2/../../../../i686-w64-mingw32/bin/ld:
cannot find -lpthread
collect2: error: ld returned 1 exit status
Versions used:
binutils 2.24
MinGW-w64 v3.0.0
GCC 4.8.2
Winpthreads configured with:
--host=$target --build=$build --prefix=$prefix/$target --enable-shared
--enable-static
It seems all the right executables are being called, but a -nodefaultlibs
is missing or something.
Any ideas? Thanks!
Ruben,
apparently getting back into building toolchains for some crazy reason.
PS: note this time round, I am actually maintaining patches for various
build issues and applying them automagically ;-)
