AIX: Argument list too long (quick tip)
If you happen to be on an AIX 5.x host using [Gentoo Prefix][1]. Then you might see something like this eventually:
/bin/sh[3]: /home/jolexa/portage/aix-5.3/bin/chmod: arg list too long
This is caused by build systems that use wildcards or even ebuilds that have no issues on a normal GNU/Linux system. To work around this, you need to change the ARG/ENV list size in 4K byte blocks. The default value in AIX 5.x is 6. This is way too small. You will either need root access or kindly ask your system administrator to change this value. To change it, you have two options: use smitty (a curses sys-admin tool on AIX) or do root# chdev -l sys0 -a ncargs=40 on the command line
If you use smitty, you are looking for this:
root# smitty
=> System Environments
=> Change / Show Characteristics of Operating System
ARG/ENV list size in 4K byte blocks [40]
40 seems to be a good number. It would be hard to guess the smallest number possible. This is not a problem in AIX 6.1, because the default seems to be ‘256’
