I am afraid Windows support is somewhat limited on master currently.

I recommend to go try the 'stable' branch instead.

borrrden commented 5 years ago

Stable is not building either. The timespec struct ends up with multiple definitions.

E.g.

xdispatch\libpthread_workqueue\src\windows\times.h(15): error C2011: 'timespec': 'struct' type redefinition (compiling source file xdispatch\libpthread_workqueue\src\windows\manager.c) 2> C:\Program Files (x86)\Windows Kits\10\Include\10.0.17134.0\ucrt\time.h(40): note: see declaration of 'timespec' (compiling source file xdispatch\libpthread_workqueue\src\windows\manager.c)

This is using the MSVC toolchain. This should be fixed on current master as of 68e917cc21e48f13bf73368a693005e9840e5079.

emzeat commented 5 years ago

I do not have the resources to also fix master for the msys/mingw toolchain though. Sorry for that. I welcome any pull requests of course.
