C program execution using gcc.

[surajms]

hi guys i m using gcc to compile certain programs.they get successfully compiled but fail to execute.Here is a sample code and the error
[tommy@tommy cprog]$ vi test.c

#include<stdio.h>
int main()
{
printf("hello"); /
return 0;

}


[tommy@tommy cprog]$ gcc test.c -o test.out
[tommy@tommy cprog]$ ./test.out
bash: ./test.out: Permission denied

a similar problem arises with codeblocks for the same program
the error is the same even when it is just main() and absence of return 0;
the problem exists also on c++.
i m using Fedora 15

It worked for me. It looks like your file permissions are not correct. Check them by trying:

[mark@localhost ~]$ ls -al test.out
-rwxrwxr-x. 1 mark mark 4740 Jul 11 22:47 test.out

If you do not see an "x" as a file permission, try:

chmod 775 test.out

Fedora mounts removable storage (USB-sticks, external hard drives, etc.) with the "noexec" option by default. If your "cprog" directory is on such a device, you can't run your compiled programs. Move your software projects to a directory under your $HOME.

try sudo gcc if u ve permission..

thank you so much guys... i tried out all three suggestions...
it seems i cant execute any program which is in a removable device which happens to be the partition of my hdd.... the program worked when i executed it from the home folder...
the chmod command did not seem to affect the file permissions...

[ tommy@tommy cprog]$ ls -al test.out
-rw-------. 1 tommy tommy 4740 Jul 11 20:32 test.out
[tommy@tommy cprog]$ chmod 775 test.out
[tommy@tommy cprog]$ ls -al test.out
-rw-------. 1 tommy tommy 4740 Jul 11 20:32 test.out

is it possible to toggle the noexec option for such files

Hey there,

remount with the exec option.
