Seems like a bug in this core. I already opened issues in other repositories.

It seems that this core is not prepared to include in a C file. The solution is to make conditional the include of CPP header files only when compiling with g++.

In order to get rid of the errors, please try to replace the attached files in the directory \Arduino_STM32\STM32F1\cores\maple. cores-maple-include-files.zip I have tested and it works for me but please let me know if this resolves the issue for you, too.

Have you managed to try my suggestion?

This commit should solve the problem.
