The log shows

configure:8796: checking for pthread.h
configure:8796: gcc -c -g -O2  conftest.c >&5
conftest.c:82:10: fatal error: pthread.h: No such file or directory
 #include <pthread.h>
          ^~~~~~~~~~~
compilation terminated.


so it is not finding the winpthreads package you installed.

You might be ablke to set the  "CFLAGS" env variable to
"-I/path/to/winpthreads/include" to get it to work. Might
need LDFLAGS="-L/path/to/winpthreads/lib" too.

Regards,
Daniel

Hi,

I tried that out, I got a new error about pthreads in my config.log.

Could you take another look.

Thanks again,

Reza
