Hi Samuel, re: > Dave and I have been trying to use 'yum update gcc-c++' or > 'yum install gcc-c++' with no success. To find out exactly which package to install using yum, do the following on your fully configured RedHat Enterprise 5 workstation: rpm -qf `which cpp` This will list out the full name of the package that needs to be installed on the machine(s) that don't have complete development environments. > The machine seems to be up-to-date as far as it's packages, but a simple > 'cpp hello.cpp' doesn't even work. it gives "cpp: error trying to exec > 'cc1plus': execvp: No such file or directory" This is more involved than C++ not being installed. It is as if C++ is installed, but some piece of the installation is missing/bad. > We were wondering if that's an option for Redhat Enterprise 5 64 bit edition I am assuming so, but I have no way of guaranteeing this as we do not have a RedHat Enterprise 5 system in-house that we can use to verify the exact procedure needed. Can you give me access to the machine on which you are having problems? If the machine is not accessible from outside of the CUP campus, this may require that you (re)give me access to shu.cup.edu after enabling shu.cup.edu to have access to the machine in question.
