I like to learn programming in C. Since I use SuSE-Linux 9.0 I read the book "C-Programmierung unter Linux" from SuSE-Press which seemed to me a good introduction in C. Already the first programms won't be compiled (with command: "gcc -o filename filename.c" as advised in the book). I get a file which shows (in kde) the icon for executeable but doesn't start. If I use the command "cc -o ..." I get an empty textfile and think, that the executable file is also empty. To be sure I have no errors in programmcode I tried it with the code from SuSE internetsite too, with the same result. >From SuSE I didn't get any help up to now, so I try it this way. Can you tell me what is wrong in my doing? Thanks in advance. Helmut
