[gentoo-user] Gentoo glibc-2.3.2 install help

[CJ Keist]

Hello all,
     First time user of Gentoo.  We're wanting to run Matlab R14 SP2 
64bit mode.  According to Matlab site they support the Linux kernel 
2.6.x and glibc-2.3.2.  Non of the current linux distro (i.e. Fedora) 
has that old of glibc.  So looking at Gentoo thinking I can build the 
Gentoo system based on glibc-2.3.2.
     I'm doing a stage 1 install, and not quite understanding this 
portage tree stuff.  I have tried to put the following in 
/etc/portage/package.mask:

     >=sys-libs/glibc-2.3.3

and /etc/portage/package.unmask

     =sys-libs/glibc-2.3.2-r12

but bootstrapping the system is failing with deps on glibc newer than 
what I want.  Am I going about this wrong????

Have people reported any problems with newer versions of glibc?  If not, you should at least try a current stable version.

If you want to run an old version of glibc then it's probably easier if you use an old portage tree.  Maybe you can use an old gentoo release cd.

Yes,
     Running Matlab on current release will just core dump.  Also tried 
the fix on Matlab site where you modify the .matlab7rc.sh file.  So I'm 
thinking it has to be a problem with the new glibc on current releases. 
  This is on Fedora 3 and 4 as well.  Fedora 2 sort of works but not well.

That's pretty ridiculous if you ask me.  Will they let you build it from source?

No, Matlab is 3rd part software package. It's not free.

Some software companies allow licensed users to build non-free software from sources.  It's the least they can do.

You could try messing with LD_ASSUME_KERNEL

http://people.redhat.com/drepper/assumekernel.html

I think you'll have to set it to 2.4.1

So, install the glibc that comes with portage, and forget trying to 
install an older glibc.

I think your best bet is to install Gentoo with the current
glibc, and then download, configure, compile, and install
the 2.3.2 version to /usr/local yourself.  You should then
be able to start Matlab with
"LD_LIBRARY_PATH=/usr/local/lib" and have it pick up the
older glibc instead of the current.

This should also work on any Linux, not just Gentoo.
