compiling 32 bit application on 64 bit linux(x86_64)
hi all,
i have a 64 bit linux machine.
$uname -a
Linux SVRDELLD30 2.6.9-42.ELsmp #1 SMP Tue Aug 15 10:35:26 BST 2006 x86_64 x86_64 x86_64 GNU/Linux
here by default gcc creates 64 bit executable. but for some reason i want to create 32bit executable.
first i want to create 32 bit object files(.o files) and then i want to link those object files.
Please suggest me suitable gcc options.
Thanks and Regards,
uttam hoode

Hi.
I need to migrate the whole unix environment from a Unix mp-ras 32 bit to a Linux Suse 64 bit.
1) can i use cpio to copy the data?
2) can i just copy the users from unix to linux or do i have to create them by hand
3) are there any other concerns i should worry about?
