Rejected? What was the path and what was the error message?

Perhaps it helps, if I explain what is done with the given paths:

The codetools has a built in heuristic:
First it asks the compiler to get the markros and unit paths. These unit
paths normally point to directories like /usr/lib/fpc/1.0.7/units/linux/...
Then it searches for all .ppu files in the unit paths.
Then it searches all .pp/.pas files in the fpc source path and creates an

When the IDE starts up and whenever you change the fpc compiler or source
path in the environment options the IDE checks if the compiler executable
has changed. If it has changed the unit index is rebuild.

Because the fpc sources are full of IFDEFs the codetools can't parse them
without the makros. So, the compiler filename _must_ be valid.

No. It's probably just a typo.

Maybe. But I need more information.
The exact paths in the environment options.

Just 'Abort'?
