rm /e/OpenModelica.git/build/bin/omc.exe and try again (or do git clean). There was a change to the bootstrapping interface recently, which causes this issue if you have an old omc that you compile through.

Thanks for your reply. I did it and error changes to:

Did you do a git clean of all repositories? The Windows build is working, so a git clean should solve the problem...

When I clean whole repository, build folder is gone, and by running "make -f Makefile.omdev.mingw runtimeCPPinstall" again, it stops with this error:

For making build folder, I run "make -f Makefile.omdev.mingw -j8" but it also stops with following error:

After calling gitclean several times, It works. Thank you

I am running the cpp runtime test with, cd OpenModelica\testsuite\openmodelica\cppruntime and make command, but OMedit test is not working. Is there any idea to resolve it?

Equation mismatch: omc-diff says:
Failed '<' '"'
Line 7: Text differs:
expected: messages = "<message stream=\"other\"
type=\"warning\" text=\"Warning: unrecognized command line
options
got:      messages = ""
