Hi.

I just start to play with PB 3.0.3

I created simple package, add one dummy txt file to compres and add one custom action to initialization - Exit package.

Whe i try to compile it, i got a lot of “warning #2154” messages. Is that normal?

Compressing Files
Initializing compression routines...
Skipping file compression: the cached archive file is used since no changes were done to the file list.
Note: to force Paquet Builder to compress the files again, use the "Build Full Package" menu command in the "Build" menu, or press F10 instead of F9.  

Finalizing Package

It’s because you are using label and goto custom actions, and somehow you have “dead” code, which means it is never reached nor executed. The C compiler is able to detect that dead code and shows these warnings. It doesn’t mean your package won’t work, it’s just that you left custom actions that will never be executed.

Thanks for answer.

But as i wrote - i only added Exit to custom action - no labels/goto actions.
Look on attachement.

If you have custom actions after the Exit that are never called or executed, you’ll get the same warnings.
