With support for Red Hat Enterprise Linux 4 introduced by ColdFusion MX 7.01, a C++ compatibility pack warning may be erroneously presented during ColdFusion installation. The ColdFusion MX installation script uses the command rpm --query compat-libstdc++ to ascertain if the C++ compatibility pack is installed on the system. The actual RPM package name is not compat-libstdc++ so the rpm command does not return a successful result and the CFMX installation script produces warning.

To more accurately determine the status of a C++ compatibility pack on the system, the ColdFusion MX installation script should either query all packages and use the grep command as a filter or query the exact package name. For example, the command rpm -qa | grep compat-libstdc++ queries all packages and filters or greps on the string compat-libstdc++. On my RHEL4 system, this command produced two results, compat-libstdc++-33-3.2.3-47.3 and compat-libstdc++-296-2.96-132.7.2.
