LazEdit is in the CCR, but I wasn't sure where to put this, so I hope here will be ok.
When compiling on Linux, I found out that unit LazEdit_PicsLib has Windows unit in its uses section, so it wouldn't compile. Changing that to:
uses LCLIntf, LCLType;
solved the problem, it compiles, and so far works normally in Linux. Should I report a bug somewhere or is this enough for someone to make the (small) change?
