Compiled program won't execute

[navic]

When I compile anything with GCC the output executable will not set the executable permission - I've tried chmod +x filename and chmod 755 filename both have no effect on the file at all. This is happens only on removable drives... what am I doing wrong??

It may be a permissions problem.

1. What's the format of the external drive? ext3 or ext4, or what?
2. Is your user (you) the owner of the drive?
3. Have a look here http://superuser.com/questions/57092/cant-change-permission-ownership-group-of-external-hard-drive-on-ubuntu

Good luck!

Out of curiosity, what are some of the things you are trying to compile?

Thanks powerhouse. I am the owner of the drive and they are either NTFS or FAT volumes. The link you gave me says Linux doesn't support FAT permissions but these drives work fine in Mint 9 so I'll just stick with 9 until April and hope the next Mint LTS doesn't do this weird permission thing because I depend too much on being able to execute programs from NTFS/FAT volumes.

Hello world... it compiles fine and writes the output file but I can't get the execute permission to take effect

Hi
Are trying to follow some tutoriel? if so, can you share with us your source just to make sure you did everything alright

Nope, trying to understand the differences between Mint 9 and Min 13.... There are no source code problems, the only problem is that I can't make a file on a removable volume executable in Mint 13. The file doesn't matter if it's a hello world program I just compiled or an already compiled file that existed on the volume already.... none of them can become executable in Mint 13 only... all works fine in Mint 9.

I don't think it's an issue with Mint 9, I have been using it since it came out. I don't have access to a Linux box now (I'm traveling with my Macbook) but somewhere in the back of my memory I recall some security or whatever settings that would disable you from executing files on external drives. Ah, did some searching and found this:

It looks like Linux Mint or Ubuntu have, at some point of time, removed execute permission for external drives. The above link should help you to enable that. You can find more information when you Google for "can't set permissions for files on an ntfs partition".

Hope it works.

Thanks for link, it works but what a pain. Now that I think about my setup of running Linux on machines and using NTFS removable media in case someone needs to copy something onto a Windows machine is just dumb. I'm moving it all to the cloud and will pull down items to work on locally so I don't have to make this change on 10+ machines.
