Description petrk 2016-08-21 13:57:53 UTC

LLVM was built from IDE with g++ 5.3. After building IDE asked to add tool collection CLang (which was just built) and set CLang as a tool collection for LLVM project. But the compiler which was used is g++!

Could you provide steps to reproduce?

Comment 2 petrk 2016-08-22 10:03:24 UTC

Just build LLVM 36 from scratch. Instruction is available at spuitnik/contrib/JConvert/docs/GettingStarted.txt

Comment 3 Alexander Simon 2016-08-22 10:32:41 UTC

Investigation:
Build procedure invokes
gcc 23 times,
clang 1546 times and
g++ 2033 times.

New project wizard use following algorithm to detect tool collection:
1. Analyze C compiler invocations. Win C compiler which was called more times.
2. If there is no C compiler invocation the wizard detect tool collection by C++ compiler invocations.

According to algorithm the primary tool collection for your project is CLang.

Note:
IDE does not support multi tool collection projects
