Hello all,

I'm getting error messages like this

My host system is Ubuntu 19.04.

I'm using an ARM GCC cross compiler toolchain in a project with both C and C++ code.

The problem seems to occur for C++ files, but not for C files.

When I check the Entries tab in the project settings "Preprocessor Include Paths, Macros etc.", for GNU C, there are include directory entries below CMAKE_EXPORT_COMPILE_COMMANDS Parser and include directories and macros below CMAKE_EXPORT_COMPILE_COMMANDS Compiler Built-ins, but nothing for GNU C++.

The CMake toolchain file specifies

set(CROSS_TOOLCHAIN_PREFIX arm-none-eabi-)
set(CMAKE_C_COMPILER "${CROSS_TOOLCHAIN_PREFIX}gcc")

There is no specification for CMAKE_CXX_COMPILER

Here are two example sections in compile_commands.json, one for C and one for C++

Why is the parser not able to process the C++ compile commands?

Best regards,

The compiler name does not match any recognition pattern. For C++
cross compilers, (e.g. arm-none-eabi-gcc), the pattern is
".+-g\+\+"

Please file an issue at
https://github.com/15knots/cmake4eclipse/issues that requests to add
pattern ".+c\+\+".
