Re: [Mingw-users] OpenMP static build (link pthread statically), what's the alternative?

The static library corresponding to pthreadGC2.dll 

I'm far from an expert here but apparently someone has built either GCC or libgomp (or both) in 'shared' mode and now the OP is banging his/her head against the wall since there is no way the OP could revert this 'shared' mode.

To my mind, this issue has nothing to do with pthreads library, but GCC or gomp (or both). Take a look at this:

c:/mingw/bin/../lib/gcc/mingw32/4.7.2\libgomp.a(parallel.o):(.text+0x66): undefi
ned reference to `_imp__pthread_mutex_lock'
c:/mingw/bin/../lib/gcc/mingw32/4.7.2\libgomp.a(parallel.o):(.text+0x86): undefi
ned reference to `_imp__pthread_mutex_unlock'
c:/mingw/bin/../lib/gcc/mingw32/4.7.2\libgomp.a(parallel.o):(.text+0x14f): undef
ined reference to `_imp__pthread_mutex_lock'
c:/mingw/bin/../lib/gcc/mingw32/4.7.2\libgomp.a(parallel.o):(.text+0x169): undef
ined reference to `_imp__pthread_mutex_unlock'

Have fun.
