[Coco] Question about compiling C in OS-9

[Boisy G. Pitre]

You're right Bob. I went back and looked at the thread and he does have a main function.  One thing I find puzzling though is that in his c.prep test.c output, the main function did not show up (Todd, I presume that you pasted the entire output of the c.prep command).

Still there is no doubt at what the linker is telling us. It fails to see a main function which is required for resolving. I would be inclined to run c.prep test.c again and just verify that there is a main function in there.  If not, then I would look at the source itself.  Line ending issues perhaps?
