What is the correct way to work with another C ++ compiler in a CDT project?

Question

I am using Eclipse CDT Mars.2 (and Neon RC) on Linux. My default distribution is the C ++ compiler GCC 5.3.1, but for some of my work I use GCC 4.9.3. I would like everything related to my project to use GCC 4.9.3: Tool discovery, C ++ standard library, included file paths, indexer, preprocessing - all this.

What is the right way to do this? It seems that Eclipse has quite Byzantine configurations “providers” and “bindings”, and I don’t want to make settings that I can’t cancel later ...

Note:  I tried replacing ${COMMAND}with /usr/bin/g++-4.9in some settings the preprocessor provider, etc., and this led to the detection of related files related to 4.9.3, but my indexer did not like it, and all std :: material appeared red and unresolved. Then I tried to find where I installed the compiler version used for indexing, but I could not find it.

, , " Make" "Mangaged Make". Make , Make . Managed Make , CDT Makefile .

${COMMAND}:

• ( )
• C/++ General → Preprocessor Include Paths, .. .
• "".
• CDT GCC
• ${COMMAND} Command, : g++.
