- Subject: Building Relocatable GCC
I'm trying compile a version of gcc-4.5 on linux x86 for linux x86 which
is relocatable but I'm having difficulty.
Does anyone have an example of how to build such a relocatable gcc?
I've been building binutils, and gcc-4.5 over and over
with many different options. After reading the docs I thought the key
configure options are the --with-sysroot=/my/root and --prefix=/my/root
for both binutils and gcc with those options and it should be
relocatable but I've had no luck. For most of my attempts I can compile
binutils fine but gcc compilation fails saying it cannot file system
headers in /my/root/usr/include.. Am I missing a step somewhere? I've
even tried the bringing in eglibc/libc into the mix and trying to create
a cross-compiler from linux x86 to linux x86 but that was even worse.
>From the googling that I've done it doesn't seem like it's that
difficult. I think I'm missing some critical step somewhere
Cheers,
