Hi I have debugged the problem that gives sig 11 from within the IDE, to the following. The IDE never compiles the code and produce the binary executable. Also, if I cd to the dir & type $ gbc ./ I get "OK" on the screen and nothign is compiled. gba works OTOH. Is this the problem. what should happen with "gbc ./" and what's the diff bet gba & gbc thnx
