Hello,
I must test a software with a older version of the glibc. I
run
the
2.11.1 now but for one tool I need a previous version
(2.6.1).
How can I compile the glibc without changing my system
glibc. I
would
like to set the previous glibc with the LD_PATH.
Can I run two different versions or is a better solution to
downgrade
the system glib?
I think that the only way you can do this is to create a
chroot
jail,
in which you build everything using the old version of glibc
(in a
very
similar way to building a new Gentoo system) and run your
application in
that.
no, you can install glibc in /usr/local and then tell apps to
either
use the
libs in /usr/local or /usr.
It is just not easy because it easily breaks stuff in horrrible
to
fix ways.
Okay, can I downgrade my glibc? My Gentoo isn't a big system, it's
a
server
installation, so I can recompile the whole system. I had forgotten
to
mask the
glibc on the last update. I have add a line to the portage.mask
but
emerge says
that it can't compile the older version, because will damage the
system.
Would LD_PRELOAD solve your problem? - worked for me when needing to
run
a legacy redhat app in the past on a more up-to-date gentoo system.
I think that can solve my problem, because it's only this one lib all
other libs
work very well.
There is also a LD_LIBRARY_PATH variable. Get a binary copy of the
libs
you need and put em somewhere convenient and let the rest of the
system
stay as is.
I don't have the glibc binary. I can't emerge it and if I try to
compile from the sources.
The configure script says: These critical programs are missing or too
old: as ld
How I can compile the from the sources
(http://ftp.gnu.org/gnu/glibc/glibc-2.10.1.tar.gz) ?
You can use ebuild to build a package, but not install it - then just
un-compress it and grab the wanted libs.
I will try it on my system first, because I can lean something new.
Or if you tell us what arch,
someone (me if its compatible) can create a binary pkg for you using
quickpkg. It might also be on the livecd/install medium as well -
dont
have one here to check.
I run my Gentoo on amd64 (intel xeon), thank's for help.
two glibcs with different version
