adding an existing implementation file to an xcode project won't work
- by karsten
As I write most of my code using MacVIM, I need to add the new files to the XCode project in order to compile them into the executable. Today however I encoutered an implementation file (.m) wich XCode won't allow to be added. It appears light gray the appropriate finder window as if it were already included in the project, but when I try to build, I get a linker error, stating that the symbol defined this implementation file could not be found. The corresponding header file could be added without problems.
Any idea what could have caused this problem?
Btw. I deleted a former version of the same file from the "Classes" tree before, as well as many others wich were successfully re-added.
Thanks in advance.
