meson test with cross compile fails

[adrianjohnson]

I am building on Linux, cross compiling for i686-w64-mingw32. When running meson test I get the error

Meson test encountered an error:

The exe_wrapper defined in the cross file 'WINEPATH="/usr/i686-w64-mingw32/lib;/usr/lib/gcc/i686-w64-mingw32/10-win32" wine' was not found. Please check the command and/or add it to PATH.

My cross compile file is

[binaries]
c = '/usr/bin/i686-w64-mingw32-gcc'
cpp = '/usr/bin/i686-w64-mingw32-g++'
ar = '/usr/bin/i686-w64-mingw32-ar'
strip = '/usr/bin/i686-w64-mingw32-strip'
windres = '/usr/bin/i686-w64-mingw32-windres'
pkgconfig = '/usr/bin/i686-w64-mingw32-pkg-config'
exe_wrapper = 'WINEPATH="/usr/i686-w64-mingw32/lib;/usr/lib/gcc/i686-w64-mingw32/10-win32" wine'

[host_machine]
system = 'windows'
cpu_family = 'x86'
cpu = 'i686'
endian = 'little'

[properties]
needs_exe_wrapper = true

Initially I had exe_wrapper set to exe_wrapper = 'wine' but then I would get the following build error:

I added the WINEPATH to the exe_wrapper and that fixed the sanitycheckcpp_cross.exe problem. But it appears meson test does not like the WINEPATH in the exe_wrapper.

I tried removing the WINEPATH from the exe_wrapper and setting it in my environment before building with meson. Now when running `meson test cairo -v --num-processes 1 I get the error:

There's unfortunately no way to pass environment variables though the cross file directly. You can use a shell script wrapper for that purpose though.
