Re: Getting 32 bit linux binary support

[Cameron Kelly <cam.k801%gmail.com@localhost>]

Hello,

When I try to run modload compat_linux32 as root I get the following error:

modload: compat_linux32: Exec format error

however, when I run modstat | grep compat_linux, I get the following:

compat_linux               exec     builtin  -        0       - 
compat_ossaudio,sysv_ipc,mqueue,compat_util,compat_50,compat_43,exec_elf64,exec_aout

Which it seems like the module for the 64 bit support is loaded fine.
