Unable to cross compile spdlog for x86_64-windows-gnu

[przybysh]

Zig Version

0.11.0-dev.3724+32cb9462f

Steps to Reproduce and Observed Behavior

Operating system:
cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=22.04 DISTRIB_CODENAME=jammy DISTRIB_DESCRIPTION="Ubuntu 22.04.3 LTS"

1. Checkout spdlog library
   git@github.com:gabime/spdlog.git
2. Go to the spdlog dir and configure CMake project
   cd spdlog && CC="zig cc -pthread -target x86_64-windows-gnu" CXX="zig c++ -pthread -target x86_64-windows-gnu" cmake -B build_zig

Expected Behavior

Would expect that project configure with succes.

Instead got :

CMake Error at /usr/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find Threads (missing: Threads_FOUND)
Call Stack (most recent call first):
  /usr/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:600 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake-3.25/Modules/FindThreads.cmake:228 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:144 (find_package)

Zig toolchain does not have winpthreads.

Reference

• zig c++: 'pthread.h' file not found for target x86_64-windows-gnu #10989 (comment)

@przybysh,

I tried spdlog v1 branch (default) on my machine and the error I got does not match the one mentioned above.
Furthermore, your commands are incomplete!

zigcxx

#!/usr/bin/env bash

$(which zig) c++ -fno-sanitize=all -target x86_64-windows $@

Thank you for your input. With following command
CC="zig cc -fno-sanitize=all -target x86_64-windows-gnu" CXX="zig c++ -fno-sanitize=all -target x86_64-windows-gnu" cmake -B build_zig -DCMAKE_SYSTEM_NAME=Windows -DCMAKE_CROSSCOMPILING=true -GNinja
I was able to cross-compile and run spdlog example under wine.

Issue can be closed.
