Answer 1

On Windows, with Eclipse CDT Oxygen, none of the solutions described here worked for me (including the "Provider" - "CDT GCC Built-in Compiler Settings"). What works for me is:

• Install Cygwin, with notably the following packages (maybe not all are strictly needed for this):
  • libgcc1
  • cygwin32-gcc-core, cygwin32-gcc-g++
  • gcc-g++
  • mingw64-x86_64-gcc-core, mingw64-x86_64-gcc-g++
• In Project Properties:
  • Go to "C/C++ Build" - "Tool Chain Editor" and select "Cygwin GCC" as the "Current toolchain":
  • Go to "C/C++ General" - "Preprocessor Include Paths, Macors etc.", in the "Providers" tab, select:
    • "CDT Users Setting Entries" (I need them for other includes, such as the Google Test ones, which I manually referenced);
    • "CDT GCC Built-in Compiler Settings Cygwin".
