I'm getting pthread linker errors when building libschroedinger for mingw32.
This is my configure line:
./configure --with-thread=pthread --with-gnu-ld --disable-gtk-doc
--enable-static --disable-shared --host=x86_64-w64-mingw32
--prefix=/usr/local/x86_64-w64-mingw32
I'm not using --with-thread=win32 because my frontend uses pthreads. I don't
want any type of answer even remotely close to "use win32 threads." I'm
using pthreads. Period.
It compiles just fine, but this is the linker error:

When I run x86_64-w64-mingw32-nm on
libschroedinger_1.0_la-schroasync-pthread.o, it does show those symbols with
a U (undefined). However all the symbols are in libpthread.a except without
the __imp_ in the front i.e. in libpthread.a there's pthread_join, not
__imp_pthread_join.
1. Are these undefined symbols actually trying to reference the ones without
the __imp_ at the beginning?
2. I couldn't fine these defined anywhere, so doing find-and-replace on the
source code is a little difficult.
3. How can I make it so it is actually referencing the symbols in
libpthread.a (e.g. pthread_join) and not these undefined things (e.g.
__imp_pthread_join). I already tried adding -DNO_PREFIX to CPPFLAGS and
CFLAGS before configure, then re-configuring. That didn't work.
Thanx.
