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 don´t 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 can´t find the files precompiled. Is this correct? Thank you.
