FlexLexer.cpp:2429:10: error: use of undeclared identifier 'YYMUFlexLexer'
    void yyFlexLexer::yy_load_buffer_state()
         ^

Solution: Most likely, the YY prefix wasn’t set properly or at all

Solution: Check that Lexer/Parser compiled source aren’t empty! Compiling an empty source file won’t generate an error but would endup causing linker to complain du to missing code. This situation did occurred with sed command being to write-back to same file. The mitigation solution was to sed to a temporary file then rename the temporary file to the expected output filename.

Call Stack (most recent call first):
  src/lib/app/RvCommon/CMakeLists.txt:58 (quote_file2)

Solution: We need a python command available.

The newer Ubuntu, Centos & Rocky system usually won’t have python out of the box, they have a python3 interpreter.

One solution is to instyall pipenv and start a local virtual environment. That will give you a python command.

(Linux) pyconfig.h: No such file or directory

Windows 10 & Windows 11 (Windows 10+) : PIP REQUIREMENTS: py7zr fails to install

  [end of output]

        note: This error originates from a subprocess, and is likely not a problem with pip.

      See above for output.

      note: This is an issue with the package mentioned above, not pip.
      hint: See above for details.
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: subprocess-exited-with-error

× pip subprocess to install build dependencies did not run successfully.

Note: There’s an issue with the latest version of MSYS2 and Python3.xx versions. Enter the following command from the same MSYS2-MinGW64 shell if you encounter an error when installing the py7zr python requirement:

SETUPTOOLS_USE_DISTUTILS=stdlib pip install py7zr

Windows : System-wide vcpkg

Another installation of vcpkg can conflict with the one installed by the build system. Currently, there are only two possibles solutions:

Option A: Remove the automatic integration of the system-wide vcpkg into cmake using :
```
vcpkg integrate remove
```
Option B: Make sure that the right dependencies (and version) are installed in the system-wide vcpkg.
