Hello, Try to type './first' instead of 'first' When we want execute a command in the same directory we are, we should type the prefix './' by security reasons. Guillermo. On Tuesday 16 December 2003 21:32, KPP52@aol.com wrote:

Is there something I'm missing with the C compiler here? I'm new to SuSE and new to linux in general. I have done some C programming in Unix and this is confusing me tremendously. Any help would be greatly appreciated.

what you REALLY mean to do: "./a.out" -- << http://michaeljtobler.homelinux.com/ >> Scientists are people who build the Brooklyn Bridge and then buy it. -- William Buckley

Let me add some clarifications to some of the postings on this. I think that Gary gave the correct answer: gcc -o first first.c This creates the file, first, with the correct executable permissions. gcc first.c This creates a.out with the correct executable permissions. As Gary mentioned, by default SuSE (and nearly every other Linux and Unix system) does not include the current directory in your PATH environment variable for security reasons. For this reason, you must use either absolute or relative path to execute files that are not in your PATH. For this reason, to execute anything in your current directory, you must use the relative path (eg. ./<name of file> ) or the full path (eg. /home/yourusername/<path to current directory>/<filename>). So to execute first: ./first or to execute a.out: ./a,out - -- Jerry Feldman Boston Linux and Unix user group http://www.blu.org PGP key id:C5061EA9 PGP Key fingerprint:053C 73EC 3AC1 5C44 3E14 9245 FB00 3ED5 C506 1EA9 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2-rc1-SuSE (GNU/Linux) iD8DBQE/37jz+wA+1cUGHqkRAjzSAJ0bYcV09uCoGQSsKiivq4X7q8BSXACcCaEi KvO3Gwa4YJ9wVwfZNtpmroc= =EyXP -----END PGP SIGNATURE-----
