Cannot configure on macOS with GCC.

[Jhuighuy]

Summary

Hi everyone,

I cannot compile the latest oneTBB on macOS using g++ as the compiler. The issues comes from the gas version identification, but the assembler is not gas (but the LLVM one), so, the version string cannot be parsed correctly.

Version

master branch (commit d1d43adf6af117d3ab4ee3a14a5fa129e0690290).

Environment

• Hardware: Mac with Apple Silicone.
• OS name and version: macOS 15.1, g++-14 from Homebrew.
• Compiler version: Homebrew GCC 14.2.0_1 (the latest GCC from Homebrew, however, this is not imporant).

Observed Behavior

~/oneTBB (master) » CXX=g++-14 cmake .                                                                                                                                                  -- The CXX compiler identification is GNU 14.2.0

Expected Behavior

oneTBB to configure and compile 😄 .

I can suggest adding a CI pipeline for macOS and GCC.

Steps To Reproduce

$ brew install gcc
$ git clone https://github.com/oneapi-src/oneTBB 
$ cd oneTBB 
$ CXX=g++-14 cmake . 
$ # or cmake -DCMAKE_CXX_COMPILER=g++-14 .
