Oracle 11gR2 install fails due to missing packages in RHEL 5.7
 

Installing Oracle 11.2.0.1 on RHEL 5.7 (kernel 2.6.18-274.el5 and prerequisite checks shows the following packages missing:
- gcc-4.1.2
- elfutils-libelf-devel-0.125
- glibc-devel-2.5
- glibc-headers-2.5
- gcc-c++-4.1.2
- libaio-devel-0.3.106
- unixODBC-devel-2.2.11
When recompiling these RPMs, receiving message that additional packages are required. For example, an attempt was made to recompile
the gcc-4.* ( rpm -Uvh gcc-4.*) results in following:
warning: gcc-4.1.2-50.el5.src.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
error: Failed dependencies:
glibc-devel >= 2.2.90-12 is needed by gcc-4.1.2-51.el5.x86_64

Cannot find glibc-devel-2.2.90.12
Additionally, recompiling other packages results in additional packages required.

Can anyone provide a complete list of the packages required and where they might be downloaded from?

Any help is much appreciated.

yum will be easy to resolve all the dependencies, if your RHEL is registered then you can user their repository
