How do I link files together in codeblock ?

<< < (2/2)

fabien:
I did "Build"->"Build workspace"  and then the build log I obtained was :

-------------- Build: Debug in GraphsForNauty ---------------

Target is up to date.

-------------- Build: Debug in illustration5 ---------------

Target is up to date.

-------------- Build: Debug in EasyNauty2 ---------------

Target is up to date.
Nothing to be done.

And the program runs but never finish.


Then I erased the #include filex.c because as you said they shouldn't be there and I got in the build log :


-------------- Build: Debug in GraphsForNauty ---------------

mingw32-g++.exe  -o bin\Debug\GraphsForNauty.exe obj\Debug\main.o   
obj\Debug\main.o: In function `main':
C:/langageC/GraphsForNauty/main.c:226: undefined reference to `_nauty_check'

Look: The first one is not a Code::Blocks issue - you did something wrong in your application obviously. This forum can't and won't help you because it is out of the scope of Code::Blocks.

The second one is related to basic understanding of programming. Of course you receive linker errors like "undefined references" if you remove parts of the implementation. However, including plain C files instead of just header files in your code is something not very common, but maybe needed within the scope of your work. Again: This forum can't and won't help you because it is out of the scope of Code::Blocks.

Some final hints before I lock the topic as it massively violates our forum rules:
- Grab yourself a book/article about the basics of how a compiler / linker works.
- Try compiling an application of 2..n files at the command line to understand what you have to provide to the compiler / linker.
- Then return back to the (any) IDE and setup the project accordingly concerning include path's for the compiler/linker, flags for the compiler/linker, files etc.
- Instead of including the C file, add the file to your project so it gets compiled / linked into your application.
- When working with more than one source file you will need to setup a project.
