Re: compilation or linking error

I think we do not understand each other. I an using the compiler 25.0 of he community. In this compiler that includes an editor you are asked which .gpr file you want to use. As a result all files that are mentioned in the .gpr file can be reached by the editor as belonging to the project. If you open another file it is not mentioned as a file beloning to the project. The compiler just compiles only the files belonging to the project. uses the .gpr file only as a guideline howe to create an .exe file. In the program I have a BUILD command which has sub commands (CHECK SYNTAX, CHECK SEMANTIC, COMPILE FILE, PROJECT, CLEAN, RUN, SETTINGS) of which PROJECT is split into BUILD & RUN, BUID & DEBUG. I have tried CHECK SYNTAX, CHECK CHECK SEMANTIC, which are all without error, COMPILE, PROJECT/.. create errors   So what do exactly do wrong.
