Re: missing pthread.h in building 64-bit aaplications
I guess I found the reason why x86_64-w64-mingw32-gcc can't locate pthread.h. It's because a macro #if HAVE_PTHREAD #include is used in source files, but the macro is not defined by mingw, about which I found it existiing before according to google search. I re-built it after the macro was commentted, and pthread.h was in. How is your thinking? Another, I added -v and dependency output showed usr\x86_64-w64-mingw32\sys-root\mingw\include was in. So the search path mechanism is not a problem.

Add a "-v" as well so we can see where gcc searched for the headers. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

I should have picked up on that from the report.

Keep in mind that the new mingw* compilers are Cygwin-hosted cross-compilers: they use standard *NIX paths. In any case, if mingw64-x86_64-pthreads is installed, then you don't need an -I flag at all; pthread.h should already be in the default search path.

The x86_64-mingw64 cross compiler package set includes a win32-pthreads package, including pthread.h. It's necessary for gcc's OMP support via libgomp. That's why the OP was able to find one copy of pthread.h in C:\cygwin\usr\x86_64-w64-mingw32\sys-root\mingw\include. The real question is why the (cross)compiler couldn't locate it; given the whole /mingw prefix and sysroot support, it really should be able to. -- Chuck -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

This is a MinGW compiler. It doesn't support pthread.

missing pthread.h in building 64-bit aaplications
Hello All, Goal: Building 64-bit application on Cygwin OS: 64-bit Windows 7 I used "x86_64-w64-mingw32-gcc " to build the application, but failed.
