Problem with static linking of pthread

[Giorgio Medeot]

Hi all,
I'm trying to compile Stockfish, using mingw compiler (gcc version 4.5.2).
If I use dynamic linking of the pthread library all goes fine, but when I try to static link I go into troubles.
After some trial and fail, I've managed to get the code to compile, but as soon as I launch the executable, it crashes with a segfault.

Here is the compiler log:

I guess it must be some kind of compiler/linker issue, but I really don't have a clue about what can be wrong. Any hint will be really appreciated

Thanks and cheers,

I have had similar problems, but using the intel compiler. I wanted to compile on A and run on B, where A and B have different library versions, but it apparently does not quite work for reasons unknown...

[Jim Ablett]

With Windows version of the Pthread library you can only link dynamically with external dll.

Jim.

[Giorgio Medeot]

Doh! I wasn't aware of that. Also the 'read me' in the pthread sources were not clear about this (that is, were not clear to me ), though they do mention some requirement in order to build both the pthread static lib and a statically linked application.
After some more googling, I've now found some reference to the need of calling certain "non portable" functions, when statically linking. Maybe this is the problem.
Well, however that may be, I will keep the compile with the external dll.

Thanks for your help!
