Re: Problem: linux 64 bit

I still have a GC_pthread_create exception on compiling.

GC_pthread_create() is not defined, I changed the
/usr/include/gc.h and 
/usr/include/gc_pthreads_redirects.h, avoiding if statement
to have the 
methods declare.
But it's not solving the problem, GC_thread_create is not
defined:

Looks like you libgc does not include it. You'll have to
recompile libgc 
with appropriate pthreads support.

I think you can also disable threads in Neko by adding
NEKO_NO_THREADS 
to the Makefile CFLAGS
