Just for the sake of saying so: You know you shouldn't be installing from source on RPM based distros, right? The proper way to do this for them is to create RPMs. If you're going to be running them on multiple platforms, just create a src.rpm, then "rpmbuild --rebuild thepackage" on each platform you need, or "rpmbuild --rebuild --target i386 thepackage" from your 64-bit system.
Next, why would you want to create 32-bit objects on a 64-bit platform? Wouldn't it make more sense to create them on a 32-bit platform? If you don't want to go through the hassle of setting up a 32 bit system, just use the installation CD for Gentoo as that should have everything you need. Also, if you're going to insist on installing things from source, I'd recommend you just go ahead and switch to Gentoo anyway.
To answer your question: Doesn't gcc create 32-bit when you do "--target=i386"?
Next, why would you want to create 32-bit objects on a 64-bit platform?
32 bit programs are smaller and faster for programs that don't need more than 2Gig of memory. Most 64 bit processers (DEC Alpha excepted) support both 32bit and 64bit binaries, and most 64 bit operating systems support different memory models simultaneously on a process by process basis.
I've generally found that compilers on 64 bit systems build 32 bit code by default and require additional switches to produce 64 bit code. The linkers are normally able to work out what memory model the code is and will reject attempts to link code with differing models.
I am new to Linux OS. My question is that "is it possible to install 32 Bit application on 64 Bit OS?"
I have the following Redhat OS on VMware workstation.

I am compiling Qt-4.7 for 32-bit on 64-bit (x86_64) Ubuntu 8.04 desktop. I have installed all the 32-bit libraries (/lib32 and /usr/lib32) through getlibs and "apt-get install ia32-libs". But I am getting the following error while configuring the qt project as:

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?
thanx (1 Reply)
I'm looking to cover a corner case for an upcoming test cycle. Is there a way to boot a RedHat Advanced Server 4 (update 3) installed on a Power PC machine to use a 32 bit kernel? This would be similar to what is done here -> https://www.unix.com/aix/26204-aix-platform.html

I've been trying to compile an application that works on AIX 5L in 32 bit mode on an AIX 5L 64 bit mode machine. In doing so I get a lot of undefined symbol errors.
Below is a sample of what the output looks like.....
