Lost functions in external header files

(1/2) > >>

spartarra:
Good morning everyone,

Problem: Configuration of Code::Blocks 8.02 when it has to find functions from other files.

Situation: When I try to compile the attached .c code telling the compiler to look in the include file directory, the compiler says : undefined reference to '<function>'. This function has been included in the include part.

So there has to be a way of telling the compiler to tell him to look not only if the files exist, to check the functions.

Thanks in advance,

Spartarra

It's not enough to include the header-files, you also have to link against the appropriate library.

spartarra:
Project - Build options...
I select top level (debug and release at the same time)- Search directories and in Compiler and Linker boxes I add the directory.
It is not still working.

Hi,

You have set where to search for libs.
Now you have to specify libs you are using on the linker tab.

Which directory ?
The directory with the header files ?

If you want to use external functions, you need either the source files or a compiled library.
Header files are not enough.

Please have in mind, that this forum is for C::B related questions only, not a forum to teach the basics of programming.
