Problems with execl system call

Srikanth_14 — Fri, 29 Mar 2013 03:25:43 GMT

Hi,

I am using execl() system call to launch another binary executable on a HP-UX OS platform. But the execl returns a error code -1 and the description of the error is "Bad Address"
The program was compiled using the aCC compiler version 03.10. Any idea what could be the problem. Should any patch be applied to the aCC inorder to get this working.

Thanks,
Srikanth

Hello

Stab in the dark....

error code 1 is EPERM - Not super user. The programme you are calling isn't owned by root is it ? you not trying to do something you don't have permission to ?

Steven,

he got the error code -1 not the error 1.

Bad Address is notified as "EFAULT"

execl man page for EFAULT says as,

[EFAULT] path, argv, or envp point to an illegal address. The reliable detection of this error is implementation dependent.

The same code compiled on a different HP-UX machine works just fine. So was wondering if any aCC compiler or HP-UX related patches needs to be applied. Any ideas would be grealtly appreciated.

Thanks

Hi,

you can check differences in the patch versions of the different workstations with 'swlist -l product|grep aCC'

Get the aCC version on different platforms as
what `which aCC`

May be aCC problem / architecture change cause
