A common mistake is to add too many paths to the unit search paths
("Other unit files"), so the compiler finds multiple units with the same
name.
Your Lazarus project should only contain search paths of your own
directories, not to the LCL, not to the FPC sources and not to any
other package. For most projects this means the "Other unit files" is
empty. 
Make sure your fpc.cfg contains only -Fu lines pointing to directories
containing ppu files, no directory with sources (.pas,.pp).

You can clean up using menu item Run / Clean up Build
files. This will delete the ppu files created by experiments or
former configuration mistakes.

On some Linux the QT version is faster. Unfortunately there is no
debian package for that. But compiling it is easy.
