Errors when compiling examples with Code::Blocks

[kordman916]

I've been trying to get the examples included with the latest chipmunk package to compile but I get these errors:

Code: Select all

I had this problem with SFML but I was able to fix it so what do I do here?

I don't know if you're using my code::blocks project files or not, but you may find them helpful:

Take care,

:: EDIT ::
Sorry, I misinterpretted what you were saying. Looks like you aren't linking to libchipmunk.a. Open the project file, then right click on the project (from the left pane) and click "Build Options." In that window, on the left, there should be (likely) <Project File>, Release, Debug. Select your project name, then move to the linker tab. From there, add the library into link libraries. If you're using windows, you'll have to manually find the library, or in linux, just type "chipmunk" and gcc/ld should do the rest for you.
If that doesn't work, let me know.

Take care,

It looks like you are building the demo source files without linking it to the chipmunk library.

[kordman916]

And how would I go about doing that?

Linking the Chipmunk library that is...

[slembcke]

That's more of a code blocks question than anything else. While I know there are a couple of code blocks users around, you probably won't get the quickest answer around here.

Thanks you guys I linked libchipmunk.a and everything worked fine.
