yum install gcc issue

[MikeL_4]

I am trying to install gcc for an Oracle requirement and the yum install is failing with following:

If I try to install what dependencies it says it's missing, it tells me they are already installed....

Not sure where to go from here to get gcc installed, any assistance would be appreciated....

Shalom,

There is a problem with the dependency database that yum is using.

I've seen this happen from a number of causes.

Normally its comes from a third party product installed that is complicating dependency calculations.

It is not likely a problem with gcc itself.

Best way around this is to uninstall some of these dependencies its confused about or go carefully through the output and remove the third party rpm triggering the problem.

After uninstall, re-install will be handled by yum.

yum clean all

Sometimes helps.

yum is supposed to solve these problems but every once in a while gets a bit confused.

Mike,

Yum can get confused about versions and dependencies because packages can be installed from several repositories, and this can in turn cause depency failures.

First try running a "yum -y update" to ensure you have all the latest packages installed. Next install "yumex" the graphical version of Yum (yum -y yumex) and try searching for the missing depencies by name. If none of this helps visit sites such as "http://rpmfind.net/" and try searching for these specific packages and see if you can individually install these prereqs. If you manage this then try to re-install gcc.

Another slightly more risky approach is to see if you already have newer/different versions of the prereqs installed is to use the "rpm -Uvh --nodeps" or "--force" to install gcc. WARNING THIS IS RISKY AND CAN BRAKE YOUR SYSTEM.

Finally download all the packages individually and experiment with manually installing packages using "rpm -Uvh" e.g.

rpm -Uvh ./x ./y ./z

as this can sometimes satisfy the prereqs.

Good luck,
Andrew

Thanks for your help, was able to trace down what was actually failing and needed and resolved issue...

Thanks

Hi Mike,

I seem to have the same problem.

Could you please let me know what you worked out was the root of the problem and what you did to fix it.

Cheers

I removed the rpm that was failing the upgrade, and dependencies.. Then installed as new install and it pulled in dependencies and loaded clean..
