zig c++: 'pthread.h' file not found for target x86_64-windows-gnu #10989
Description
Zig Version
0.9.1
Steps to Reproduce
# on linux
wget https://github.com/official-stockfish/Stockfish/archive/refs/heads/master.zip
unzip master
cd Stockfish-master/src
make build ARCH=x86-64 COMP=mingw CXX="zig c++ -target x86_64-windows-gnu"Expected Behavior
Make a cross build with target Windows.
Notes:
- a mingw-w64 compiler on Windows (msys2, cygwin) or on Linux compiles/crosscompiles successfully that codebase
- zig compiles/crosscompiles sucessfully that codebase for other targets (eg
x86_64-linux-musl,aarch64-linux-musl)
Actual Behavior
In file included from evaluate.cpp:35:
In file included from ./thread.h:33:
./thread_win32_osx.h:32:10: fatal error: 'pthread.h' file not found
#include <pthread.h>
^~~~~~~~~~~
1 error generated.
make[1]: *** [<builtin>: evaluate.o] Error 1
The mingw-w64 shipped with Zig misses pthread.h, I don't know if this is intended.
The wiki instructions to update mingw-w64 fail when configuring mingw-w64-crt (and skips mingw-w64-winpthreads) so I built mingw-w64 using this script: https://github.com/Zeranoe/mingw-w64-build
However after updating Zig with the new mingw-w64 headers I got errors/conflicts with some libcxx files.
