I'm now using the latest release.
The ide seems to have some issues with an include folder consisting only of a dot (current directory, relative).
Both versions I have used can be coaxed into cooperating by putting the -I . in the macros (rather than as a compiler define).
The newer version reorganizes the commands and puts the -I at the end and drops the dot. Not a problem until I include debug info. Then, even though the -I (and no dot) are at the end of the CCFLAGS list as they had been in previous compiles, POCC complains.
Add "-I ." at the start of the list of CCFLAGS and it works again, even with debug info.
Not a big problem, just a note to make you aware of this apparent inconsistency in debug and non-debug runs.
