It seems I got my project compiling without problems now. Naturally, some libraries were missing, and upon having copied these to a location which I specified in "Project Options/ Paths/ Libraries" it compiled and linked successfully. Although, now I'm getting a "Killed" in Debian when I try to run the application?
Can any of you maybe clarify this bit for me though, why Lazarus/FPC is searching for the linker (ld) and various other utilities, e.g. objcopy, strings ..., in folders belonging to my local system (Mac OS X's /bin, /usr/bin)? It doesn't use neither /sw/bin/i386-linux-ld nor /sw/lib/i386-linux/i386-linux/bin/ld.
Thanks so much for your help!
