Parser support for QNX qcc and q++ compiler

[Martin Hopfeld]

Hi,

I'd like to use the QNX qcc/q++ compilers with cmake4eclipse and have eclipse Indexer support.

The QNX compiler is a GNU gcc compiler with the frontend executables qcc (for C) and q++ (for C++) files. You pass the frontend executable command line arguments to indicate which cross toolchain to use (-V gcc_ntoaarch64  or -V gcc_ntoarmv7 or even -V gcc_ntox86_64)

Compilation from CMake works fine, but cmake4eclipse does not recognize the compiler name and thus cannot extract the platform defines for eclipse indexer.

What already works is extraction of project level includes from compile_commands.json.

From the cmake4eclipse documentation I can see, that the "CMAKE_EXPORT_COMPILE_COMMANDS Parsers" do not recognize qcc/q++.

What is be the path forward for support of QNX compilers in cmake4eclipse?

I'm willing to provide compiler output and help investigate problems.

Thanks

Martin

There is an extension point allowing 3rd party compiler vendors to hook in
their compilers into cmake4eclipse.
Have a look at <https://github.com/15knots/cmake4eclipse/blob/master/
de.marw.cmake.cdt.lsp.nvidia/src/main/java/de/marw/cmake/cdt/lsp/nvidia/
NvccToolDetectionParticipant.java> or <https://github.com/15knots/
cmake4eclipse/blob/master/de.marw.cmake.cdt.lsp.arm/src/main/java/de/marw/
cmake/cdt/lsp/arm/ArmccToolDetectionParticipant.java> to see how this can be
done.

Any pull requests would be welcome, too!
