Hi..
I am compiling a fortran code which is saved in a external hard disk connected to my laptop(with fedora 22 OS). After compiling the output file created is not an executable one. it shows like,

$ ./hist
bash: ./hist: Permission denied

Now I tried to change the mod with

$ chmod 777 hist

then, it doesn't shows any error, but still the file is not executable.howcaniresolvethis?

I'm not aware of any IDL function or procedure to solve fortran compilation, linux permission and executable problems.

Security. Untrusted sources (CDs, pen drives, etc) are mounted noexec.

sudo mount -o remount -o exec /dev/...
