This looks very much like what I ran into while compiling another
project [1] in MSYS2. You should try to sanitize your path, make sure
you use the right MSYS or MINGW64 shell windows during installation,
and closing them afterwards - from what you wrote I cannot be sure you
did all that. Following the MSYS2 installation instructions carefully
is important. See also
https://sourceforge.net/p/stm32flash/wiki/Build/ for the steps I did
for a successful installation and compilation.

A question that came to my mind is: What is cmoc anyway? To answer
myself, it is a cross-compiler for a subset of C:
