Can't execute a binary file

I'm trying to run a program that I've programmed. The compilation was succesful but I can't run it, not even as root..

what does ls -l show for the file? you probably have to make it executable, which can be done with

Code:

chmod 755

which makes it rwxr_xr_x

1. Do you have execute permission for the file. ie its mode may not be set.

Code:

chmod a+x myprog

2. can you see the file - in Linux the current directory is usually not in the path. therefore you must specify it like:

Code:

./myprog

finally if it is a shell script you can run it by using the dot command like:

Code:

. ./myprog

note the space between the two dots...

Have fun -

(oops - looks like ethics was typing while i was ;-)

It still doesn't work even when all the x permissions are on, do I have to be in a special group or do I need to get something updated?

list the permissions on here with ls -la
then list exactly what you are typing to execute the binary.
