Problem with CMake`s check_type_size

[pfhgil]

Hi, I'm getting a rather strange error when installing zlib using vcpkg. I use MinGW Clang for cross compilation and my MinGW triplet for vcpkg (it differs from the standard x64-mingw-dynamic triplet only in the installation of the mingw-llvm toolchain). No error occurs when building for the host device.

I noticed that this error seems to appear on line 42 of zlib's CMakeLists.txt. This line says check_type_size(off64_t OFF64_T)

Host:

• Linux Mint
• Compiler: GCC 11.4.0

Target:

• MinGW x86_64
• Compiler llvm-mingw

Vcpkg version: 2024-02-07-8a83681f921b10d86ae626fd833c253f4f8c355b
Build type: release

Target triplet:

set(VCPKG_CHAINLOAD_TOOLCHAIN_FILE "/home/ilya/pixelfield/test-windows/cmake/mingw.cmake")

set(VCPKG_TARGET_ARCHITECTURE x64)
set(VCPKG_CRT_LINKAGE dynamic)
set(VCPKG_LIBRARY_LINKAGE dynamic)
set(VCPKG_ENV_PASSTHROUGH PATH)

set(VCPKG_CMAKE_SYSTEM_NAME MinGW)
set(VCPKG_POLICY_DLLS_WITHOUT_LIBS enabled)

Using toolchain:

SET(CMAKE_C_COMPILER "$ENV{SUNGEAR_LLVM_MINGW_PATH}/bin/x86_64-w64-mingw32-clang")
SET(CMAKE_CXX_COMPILER "$ENV{SUNGEAR_LLVM_MINGW_PATH}/bin/x86_64-w64-mingw32-clang++")
SET(CMAKE_ASM_COMPILER "$ENV{SUNGEAR_LLVM_MINGW_PATH}/bin/x86_64-w64-mingw32-clang")
set(CMAKE_RC_COMPILER "$ENV{SUNGEAR_LLVM_MINGW_PATH}/bin/llvm-rc")

Your Mingw triplet is bad potentially, CMAKE_SYSTEM_NAME ends up as 'MINGW' instead 'Windows'.

The following system names are possible on Windows:

CYGWIN - Only if using the Cygwin version of CMake.
MSYS - Only if using the MSYS2 version of CMAKE inside an MSYS environment (MSYSTEM=MSYS)
Windows - Only if the above 2 don't apply.

There may be more cases, which you can see here: https://cmake.org/cmake/help/latest/variable/CMAKE_SYSTEM_NAME.html
