Wykobi - Error: Explicit instantiation shall not use ‘inline’ specifier [-fpermissive]

Question

I am trying to make / compile wykobi library (computational geometry) using the given makefile, but I keep getting the error:

error: explicit instantiation shall not use ‘inline’ specifier [-fpermissive]

How can I solve this?

Answer 1

You can override the compiler flags set in the makefile from command line:

make OPTIONS_LIBS="-fpermissive -O3 -o" OPTIONS="-fpermissive -O3 -o"
