Support executables with multiple architectures (e.g. macOS)
Type: Bug
macOS has the notion of "universal binary": https://developer.apple.com/documentation/apple-silicon/building-a-universal-macos-binary
A universal binary runs natively on both Apple silicon and Intel-based Mac computers, because it contains executable code for both architectures.
In CMake I can request to build an universal binary by e.g. https://cmake.org/cmake/help/latest/variable/CMAKE_OSX_ARCHITECTURES.html
if (APPLE)
if(AGENT_ARCHITECTURE MATCHES "universal")
set(AGENT_ARCHITECTURE "arm64;x86_64")
...
endif (APPLE)
...
if (APPLE)
set (CMAKE_OSX_ARCHITECTURES "${AGENT_ARCHITECTURE}")
...
And in CMakePresets.json:
"cacheVariables": {
"AGENT_ARCHITECTURE": {
"type": "STRING",
"value": "universal"
}
}

@H-G-Hristov I don't think we've tested this yet. What is it that isn't working? Debug/Run buttons? CTest? All of these?
I believe it's this error: "/usr/bin/clang -arch x86_64 -arch arm64 -E -x c++ /dev/null clang: error: cannot use 'c++-cpp-output' output with multiple -arch options".
Root cause is CMake Tools is sending a custom configuration with "-arch x86_64 -arch arm64" which is invalid when -E is used, which is required by cpptools for compiler querying. We could also fix it on the cpptools side.
if two -arch switches are allowed while compiling, but not while probing the compiler, then I believe this is something cpptools needs to address. Configuration Providers should not need to send different arguments based on what is compatible with the probe switches.
@H-G-Hristov Fixed with 1.13.1: https://github.com/microsoft/vscode-cpptools/releases/tag/v1.13.1
@sean-mcmanus I started using v.1.13.1. It's still little bit early for me to confirm I'm all of the fixes that were included are woking. I'm still facing an issue with IntelliSense getting stuck at updating. So I guess it is not related to the current topic (multiple architectures). Is there a bug report that tracks such an issue? Is there something I can do to help?
IntelliSense getting stuck might be https://github.com/microsoft/vscode-cpptools/issues/9688, although in that case cpptools should be getting stuck (you'd know it's that issue if a thread has wordexp on it). Our next release may have a fix or mitigation for that.
