Similar problems are often caused by too high a compiler version. You can try to compile with a lower version of GCC.

Alternatively, this can be "solved" by removing the -Werror flag from the configure.ac file

[Masshiro]

just run sudo apt-get install mahimahi, it will work.

Or degrade the GCC version to 7.5.0
