compiling gcc 2.95.3 under ubuntu 10.04.2, x86_64

compiling gcc 2.95.3 under ubuntu 10.04.2, x86_64

[Roman Suvorov]

Hello everyone,
Not sure if this is the right place to ask this question, feel free to point me in the right direction.
I'm looking into the evolution of Linux kernel and this requires me to build some ancient releases (as old as 2.4.0) from source using GCC. I have gcc 4.4.3-4ubuntu5 installed on my lab machine but it's incompatible with these old sources, and the "lowest common denominator" would be gcc 2.95.3, so I've been trying to compile it from source - so far with little success.
It's hard but not impossible - done before by this guy: http://www.trevorpounds.com/blog/?p=111&cpage=1#comment-102. I followed all of his suggestions but so far hasn't had much luck - most recent attempt dies with the following message:
/usr/bin/ld.bfd.real: error in pic/cstrmain.o(.eh_frame); no .eh_frame_hdr table will be created.

The URL above contains a link to my stdout/stderr logs too. Has anyone here tried compiling such an old version of GCC? Any advice/help would be greatly appreciated.

Regards,
Roman.

Redirect to gcc-help.

It's going to be hard.  gcc 2.95 doesn't support using x86_64 as a host,
so you're going to have to build in in a 32-bit virtual machine or by
using mock.

You'll have other problems too.  gcc back then wasn't so standards-
clean as it is now; we have a lot of warnings and better diagnostics
that have allowed us to clean up gcc.  I don't know why you got that
particular message, and as I said I can't look at your logs.  I might
have a try myself to build gcc 2.95 later today.

Andrew.

You can have success with only minor patching when you stage a 3.x
release inbetween and use that to compile 2.95.  At least that is how
I created my 2.95 build ;)

Hi Richard,
Could you please provide some more instructions on how you got your 2.95 build using GCC 3?

I just tried using GCC 3.4.6 (from http://packages.ubuntu.com/hardy/amd64/gcc-3.4-base/download) and build from source using this command:
CC=../gcc-3.4/bin/gcc-3.4 CFLAGS=-D_FORTIFY_SOURCE=0 ./configure --prefix=~/gcc-2.95.3 --enable-languages=c,c++ --enable-threads=posix --enable-shared --host i386-pc-linux-gnu
It dies right away because it can't find cc1. I got the cc1 executable from the corresponding cpp 3.4.6 package (http://packages.ubuntu.com/hardy/amd64/cpp-3.4/download) and placed it in the same bin directory as the gcc-3.4 executable, but still nothing.
As you can probably guess I've never build GCC from source before.. but I can right away spot that the target host is i386 - I'm assuming that's due to the fact that GCC 2.95 doesn't even support x86_64?

Regards,
Roman.
