I use llvm-mingw compile windows execution file, on macOS
when I use cmake-tools set "configurationProvider": "ms-vscode.cmake-tools"
intelliSenseMode explicit set "intelliSenseMode": "windows-clang-x64"
explicit setting is coverd by configurationProvider setting
cmake-tool set intelliSenseMode undefined value, I see the source cmake-tool found this
then cpptool server select macos-clang-x64, but target platform error!!!
I think cpptool must select correct target platform（here is windows， not macos）by complie arg "--target=x86_64-w64-mingw32"
why!!!!

when cpptools select incorrect mode “macos-clang-x64” （correct is windows-clang-x64）
cpptools server will add some define in bin/macos-clang-x64.json file （
{
"defaults": [
"-D__building_module(x)=0",
"--pack_alignment",
"8",
"-D__APPLE__=1",
"-D__MACH__=1",
"-D__x86_64=1",
"-D__x86_64__=1",
"-D__PTRDIFF_TYPE__=long int",
"-D__SIZE_TYPE__=long unsigned int",
"-D__WCHAR_TYPE__=int"
],
"defaults_op": "merge"
}

）
so error mode select error macro defined
APPLE define 1

error come out here

Hi @debugee . The (first) code you are referring to as the source of the issue appears to be in CMake Tools. Did you intent to open this issue against CMake Tools? If so, I can forward it to https://github.com/microsoft/vscode-cmake-tools/issues . Though, since you're using a recent version of the C/C++ extension, the useFragments variable you're referring to would be true, so should not execute the block you're referring to.

Could you enable "C_Cpp.loggingLevel": "Debug" and provide the output from the C/C++ output channel - specifically where it indicates the configuration being provided by CMake Tools for that source file? That should indicate exactly what CMake Tools is providing and clarify whether the issue is with CMake Tools or the C/C++ Extension. Also, could you do that with the latest pre-release version (1.23.2) to confirm the issue has not already been addressed and ensure any recently added logging will be included?

[debugee]

bug is clearly，cpptool server selected mode error when cross-compile。cpptool bin server select mode use compile and args while mode undefined，but it auto select error，cmake-tool can set mode or not，this is it freedom，when cmake-tool want cpptool server select mode use compile and arg（like x86_64_w64_mingw，platform is must windows），but select error，that the problem。

Don’t you have the courage to admit the bug? cant solve the problem?

[sean-mcmanus]

@debugee You have "configurationProvider": "ms-vscode.cmake-tools" so we believe the incorrect macos IntelliSense mode is coming from that extension and not ours. We're requesting the C/C++ logging that starts with "Custom configurations received:".

[bobbrow]

@sean-mcmanus, actually, I think CMake Tools sends us no value for intelliSenseMode now and we're supposed to determine the mode based on the --targets= arg. I believe it has been this way since microsoft/vscode-cmake-tools#1789

[sean-mcmanus]

@bobbrow Yeah, I mean coming from CMake Tools due to the compilerArgs/Fragments they're sending us. However, looking at our --target handling code, I don't see any code that checks the target for -w64- or mingw to converting the IntelliSense mode to Windows, so if that's what needs to happen then it would be our bug.

[bobbrow]

I'm not 100% sure based on the earlier screenshots if this is happening, but you may also want to check and see if both _WIN32 and __APPLE__ are getting defined.

[sean-mcmanus]

@bobbrow __APPLE__ is defined in the screenshot due to the macos IntelliSense mode. I don't see any logging indication that __APPLE__ is defined elsewhere.
