binutils 2.20/gcc-4.5.1 build pass 2 reverts to targeting the host system

anakinwy · 11-10-2010, 06:11 PM

I've been trying to build a cross compiler for an i486 linux based system by following LFS 6.7 and I have successfully built pass 1 of all the tools. However, when I begin the processing of second pass builds the make process will revert the target back the host system (i'm using Ubuntu 10.10 in a VM environment) which is i686-pc-linux-gnu

Can anyone help me with this?

As a second part of the question. Is there a stripped down version of the tutorial that I could follow to build a cross-compiling toolchain and glibc library for the target system rather than rebuilding the entire filesystem? I only really need to replace the glibc and the toolchain because the exisiting system is perfectly ok.

Thanks

Hi,

If you want to build a cross compiler, shouldn't you be focusing on CLFS instead of LFS?

Quote from the CLFS home page:

CLFS teaches people how to build a cross compiler

Building CLFS teaches you how to make a cross-compiler and the necessary tools, to build a basic system on a different architecture. For example you would be able to build a Sparc toolchain on an x86 machine, and utilize that toolchain to build a Linux system from source code.

Hope this helps.

Just found it .... looks like it'll do what I need except that the compiled application that i built using the new toolchain points to a directory on my system for the dynamic libraries it needs.

Can I adjust the cross-compile toolchain so I can use it to compile things which point at the proper location of the library on the final target when I deploy the application (/usr/lib)?
