I want to use Eigen with C. I read this other post (Using Eigen in a C Project) and essentially copied it in Code Blocks 17.12. When I try to compile, a red square warning appears in the row where #include "foo.h" appears for the first time and I am getting an error saying "foo.h: no such file or directory". Has this something to do with the "building" paragraph of the aforementioned post where it says "Use a C++ compiler to build the shared library libfoo.so. Use a C compiler to build the main program, linking to the shared library. The exact build steps may vary for your compiler/platform." If yes, how am I supposed to do this, if not what do I have to do?

Did you create the `foo.h` header as shown in the linked answer? Is it in the correct path? – chtz Mar 31 '20 at 16:46

I literraly copied and pasted the blocks of code so I guess yes, it is the same as the linked answer. How can I check the path though? – Angelos Mar 31 '20 at 17:00
