Dear Ms./Mr.

When I tried to run Xcos example RLC circuit, I met the following error message:

Generate a loader file  
Generate a Makefile  
Running the Makefile

“del \*.bak”

“sorry compiling problem”

As long as the electrical related simulation will report the above mentioned error, but mechanical and control related is OK.

I recreated the RLC example?

In my computer I do not have MSVC (and not planning to use it). Use mingw either from msys2 or winlibs.

Still gcc is not on my %PATH% and could simulate without issues this setup
