As I said in my first post, I have Knoppix installed in my HD. A question: Is there any difference in the terminal commands between different Linux distributions? Perhaps the makefile is trying to use a command that Knoppix-Debian donīt recognize. If I understand the console message that I posted, gcc compiles .c files and outputs .o files and it looks that there is no problem. But after, the "ld" (load?) command canīt find the files precompiled. Is this correct? Thank you.
