Very Computer

Hi,

I'm trying to execute a simple hello world c program on uClinux (running on
Motorola M5272C3) .  I've compile it with the command "m68k-elf-gcc
hello.c -o hello -lc -Wl,-elf2flt -m5307" and it was successful.  I then
uploaded it to the target board via TFTP in to the /VAR/TMP folder on
uclinux.

The problem I'm having is I am unable to run the file on uclinux because it
is giving me a "permission denied" error when I try to run "./hello".  Iwas
told a while ago that I must change the permission for the application by
going "chmod +x hello".  However that's also giving me a "Mode must be
octal" error.  Now I am stuck on what I can do.

Any help on how to get a simple executable running would be great!

Cheers,
Benny

This probably means that your 'chmod' is a scaled-down version to save
space. You can establish the same result by executing a 'chmod 777 hello'.
The 777 is an octal number, each digit having three bits. The least
significant bit is the one that determines if it's executable. Run the
'ls -l' command on your system and you will get something like this:
-rwxrw-r-x    1    root    root    12345    Oct 22 12:00    hello
^^^^^^^^ These correspond to the permission bits. This example shows 'rwx'
as the Owner permissions. All are on, so binary '111' or octal '7'. The
Group permissions are 'rw-', binary '110', octal '6'. The World permissions
are 'r-x', binary '101', octal '5'. You can set these permissions with
'chmod 765 hello'.

Hope this helps,
