gcc 3.0 / glibc 2.2.3 cross-toolchain

gcc 3.0 / glibc 2.2.3 cross-toolchain

[Bradley D. LaRonde]

I have spent quite a bit of time trying to get a gcc 3.0 / glibc 2.2.3
cross-toolchain working.  I am not a Toolchain Builder, but I really wanted
to try this combo and I don't see any way around building it myself.

I've had some success.  Everything seems to build fine.  However, when I try
to run a simple "hello world" dynamically linked with glibc, I get this:

    <myprogram>: error while loading shared libraries: failed to map
    segment from shared object: cannot load shared object file: Invalid
argument

I think it is trying to load libc.so.6, which is in my root in /lib/,
symlinked to libc-2.2.3.so, and so is ld.so.1, symlinked to ld-2.2.3.so.

I feel like I am pretty close, but I am starting to get discouraged and
could really use some help.  I really am clueless about what
should/shouldn't work.  I'm trying to do this based on bits and pieces of
information that I've collected from countless sources.  I have heard that
gcc 3.0 isn't really "working", but I still want to try.

Here is what I've used:

   * binutils-2.11.90.0.25.tar.gz (extracted from H. J. Lu's
     srpm on oss.sgi.com; I've tried others also)
   * gcc-3.0.tar.gz (released version - no patches)
   * glibc-linuxthreads-2.2.3.tar.gz (released version - no
     patches; glibc didn't want to configure without this)
   * glibc-2.2.3.tar.gz (released version)

plus a tiny patch to glibc that looks like:

You're missing the patch to change MAP_BASE_ADDR.  You need that. 
Something as simple as changing it to 0 will work for you, since you're
building everything yourself.

If you want debugging info, of course, it's much more complicated :)

I tried applying the patch that H. J. Lu posted on linux-mips that contains
that fix, but then glibc would compile.  I'll try it again - maybe I messed
something up.  If that doesn't work, I'll try the simple fix.  Thanks.

Re: gcc 3.0 / glibc 2.2.3 cross-toolchain

[Bradley D. LaRonde]

Woohoo!  It works!  Thanks!  I was using H. J. Lu's first patch and that was
broken.  I found the second patch and it worked, except it left the first
line in rtld-ldscript.in, when it really should have removed the file
entirely.  Looks like it's right in the glibc CVS though.

Re: gcc 3.0 / glibc 2.2.3 cross-toolchain

[Bradley D. LaRonde]

I've chronicled my cross-toolchain mips-adventures at:

http://www.ltc.com/~brad/mips/mipsel-linux-cross-toolchain-building.txt

I included a copy of the glibc patch that has the MAP_BASE_ADDR fix in it in
the same directory, namely:

http://www.ltc.com/~brad/mips/

Re: gcc 3.0 / glibc 2.2.3 cross-toolchain

[Bradley D. LaRonde]

I've chronicled my cross-toolchain mips-adventures at:

http://www.ltc.com/~brad/mips/mipsel-linux-cross-toolchain-building.txt

I included a copy of the glibc patch that has the MAP_BASE_ADDR fix in it in
the same directory, namely:

http://www.ltc.com/~brad/mips/

Brad

I offered something along these lines a while ago. I even started a little site.
Unfortunately I don't have enough time to keep up with current toolchain
patches, etc. myself, but if people send me patches, along with comments,
I'll post them at my site.

It would be great to have a patch repository, for example just a directory on 
the FTP of oss.sgi.com
