Execute permission denied

[Peter Gillis]

Hi,
op sys: 11.0
machine: d220

I have just installed some software and have been getting no end of ' execute permission denied ' messages. I believe I have checked permissions on all relevant files/dirs and x is set. Does anyone have any snippets of info - what would usually cause this message to occur? Is there some hidden gem that I could check out?

thanks
Maria.

Hi,
What software ?
Are you executing as a particular user ? Is this the user that owns the software ? Can you post the ll -d listing of the top directory of the software ?

Sorry there's so many questions, but since you don't mention any other execution problems (you could try to make a little script yourself and see if that user can execute it) it must be software-related.

Regards,
Tom

I can think of 4 reasons for this error ..
1) Files or directories permission not set correctly (including SUID if applicable)
2) Files or directories ownership not set correctly.
3) The executables/programs are not compatible with the hardware.
4) Environment variable PATH is not setup in the right order of path.
It would help if you provide more details.

Hi


1)file software
file /stand/vmunix

Are the results compatible.

2)Is the disc used NFS mounted or somesuch.

Check permissions on mountpoint.


Most likely is software compiled on a non compatible hardware

check for the permission and ownerships for the directory were your executables resides.

Assuming you have check not only filepermissions, but also directory permissions..:

Are there some files which should be binaries, but are downloaded as asci (by ftp or so)...: do 'file [files]'.

Hi, Thankyou for all your replies. Here is some of the info requested: Software is CA-Jobtrac Agent for UNIX. owner=root, and i am tring to start the s/w as root. ll -d listing of top directory is attached.
I have issued file /stand/vmunix (PA-RISC1.1 executable - not stripped. file on some of the key files in the ca s/w show : PA-RISC 2.0 shared executable dynamically linked; commands text. So what is the difference between PA-RISC1.1 and PA-RISC2.0? (I know I am showing ignorance here but..)
files are not nfs mounted.

Thanks again for all your info.

Sorry Maria, your D220 dog won't hunt. The code you have won't run on your D-box. Your D220 has a PA7300LC processor and you need at least a D270/D370 with a PA8000 processor to execute the code. You might see if your vendor has a version compiled with the +DAportable option. That will run on essentially all platforms. In essense, your programs are trying to use instructions that your CPU does not understand.

Thanks Clay - What was it in the info I gave that pointed to this result. Hopefully I will be able to pick this up myself next time!

Actually, I just stumbled across this thread at the right moment. As soon as I saw your 'file' command output and saw that you were a D220, I knew what the problem was.

What really happens is that as soon as the OS attempts to fork() and exec() this code, it notices that the 'magic' number is wrong and exits. 'Magic number', as well as 'Magic Cookie', are real technical UNIX terms.
