When you create a new project, in a Menu sequence: "Project" - "New project" - on the opened window double click the first entry and choose the "language" to be the linker. This is a first-time option, you could not edit this property if you have more nodes added. You will have something like a make file in the project file as the assembler/compiler directives for each "node" will be stored in this project file. You shouldn't edit it (too much) by hand, though. I have tryed this and ended up with a useless file - God save the backups;-) Hope this helps. Francisco Tommy F.
