Undefined Reference to functions, that CAN be found

(1/1)

Carola:
Hi!

I'm using GNU's gsl-library, which I installed and configured in C::B,
When I try to build, C::B gives me the following error messages:

When I right-click on the function, and choose:
Find declaration of: "gsl_matrix_alloc"
it can. And simply opens the header file in which it is stated.
Which I interpret as the library being configured correctly (true?).

So why are they "undifined references"?
Any suggestions?
Cheers, Carola

No !

Header files and link-libraries are not the same.

You should read a book about how a compiler, linker etc works.

Be aware, that this is not a general programming forum.
Your question has nothing to do with C::B and therefore violates our forum rules.
