system error when upgrade glibc in a cluster with Red Hat linux
 

Hello,

I would like to upgrade glibc to glibc-2.7. I downloaded glibc-2.7.tar.gz as well as glibc-linuxthreads2.5.tar.gz, and try following commands:

#tar -zxvf glibc-2.7.tar.gz
#cd glibc-2.7
#tar -zxvf ../glibc-linuxthreads-2.5.tar.gz
#cd ..
#export CFLAGS="-g -O2 -march=i486"
#./glibc-2.7/configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin --disable-sanity-checks
#make
#make install

However, the system returns error when I set configure as below

[root@console test]# ./glibc-2.7/configure --prefix=/usr --disable-profile --ena
ble-add-ons --with-headers=/usr/include --with-binutils=/usr/bin --disable--sanity-checks

I do not know how to solve this problem. Could anyone help me?

Thanks a lot!

Welcome to LQ.

Sorry, but glibc cannot be replaced.
( Glibc is your OS ( together with the kernel.))
All installed packages depend on the original version. ( 2.5 ? )


About your issues : A non working gcc. # yum install gcc-c++
will install all the packages, required for gcc to work properly.
