I have a custom toolchain that I want to use to compile a console C++ project for a different architecture.
I've tried modifying the "GCC_VERSION" property in the Build Settings of the project, but if I do that then Xcode just informs me that I'm using an "Unsupported Compiler".
How should I go about doing this?
I found the following link on Google but now it 404s:
This is a late answer but anyway.
People say it is possible with custom toolchains. I didn't make a research on them because easier solution worked well for me:
"
It is also possible to run frontend plugins directly by setting appropriate "build settings" of xcode. (Several ways to do this, you can set them on the command line for instance: xcodebuild build FOO=bla.) Here are a few build settings that I found useful to inject C flags: OTHER_CFLAGS OTHER_CPLUSPLUSFLAGS or to replace the compiler(s) and linker(s): CC CPLUSPLUS LD LDPLUSPLUS LIBTOOL The same approach works to control the "analyze" action: CLANG_ANALYZER_EXEC CLANG_ANALYZER_OTHER_FLAGS Disclaimer: some of those build settings are undocumented (afaik). Use at your own risk.

For me it was enough to define the following User-Defined Settings in Build Settings of Xcode projects:
CC=my-c-compiler
CXX=my-cxx-compiler
LIBTOOL=my-linker-for-static-libraries
Hope this helps.
