use different glibc version

Currently I have glibc which does not support epoll, so I installed new glibc at non default lation which supports epoll. I have python program which uses this epoll.

I tried to set LD_LIBRARY_PATH

export LD_LIBRARY_PATH="/home/glibc/lib:$LD_LIBRARY_PATH"

then I run ls, it gave me errors

ls: /home/glibc/lib/tls/libc.so.6: version 'GLIBC_2.4' not found (required by /lib/libpam.so.0)

ls: /home/glibc/lib/tls/libc.so.6: version 'GLIBC_2.4' not found (required by /lib/libpam_misc.so.0)

Also when I tried to run python I got

python: relocation error: /home/glibc/lib/tls/libc.so.6: symbol _dl_out_of_memory, version GLIBC_PRIVATE not defined in file ld-linux.so.2 with link time reference

How can I use newly installed glibc instead of default one?

If you compiled glibc yourself you should have testrun.sh script in your build directory. This is simpler and more reliable than using ld-linux.so:

build/testrun.sh ls

You need to use an explicit invocation of the dynamic linker, so something like this:

/home/glibc/lib/ld-linux-x86-64.so.2 --library-path /home/glibc/lib /usr/bin/python

(But the fact that the GLIBC_2.4 symbol version is not available suggests that something is very wrong with the new glibc, or it is actually not very new at all, predating glibc 2.4.)
