Think I've answered this myself jonesc@localhost /data/download > rpm -qlp gcc-c++-3.4.5-2.i386.rpm warning: gcc-c++-3.4.5-2.i386.rpm: Header V3 DSA signature: NOKEY, key ID 443e1821 /usr/bin/c++ /usr/bin/c++filt /usr/bin/g++ /usr/bin/i386-redhat-linux-c++ /usr/bin/i386-redhat-linux-g++ /usr/lib/gcc /usr/lib/gcc/i386-redhat-linux /usr/lib/gcc/i386-redhat-linux/3.4.3 /usr/lib/gcc/i386-redhat-linux/3.4.5 /usr/libexec/gcc /usr/libexec/gcc/i386-redhat-linux /usr/libexec/gcc/i386-redhat-linux/3.4.3 /usr/libexec/gcc/i386-redhat-linux/3.4.3/cc1plus /usr/libexec/gcc/i386-redhat-linux/3.4.5 /usr/share/doc/gcc-c++-3.4.5 /usr/share/doc/gcc-c++-3.4.5/ChangeLog /usr/share/doc/gcc-c++-3.4.5/ChangeLog.1 /usr/share/doc/gcc-c++-3.4.5/ChangeLog.2 /usr/share/doc/gcc-c++-3.4.5/ChangeLog.3 /usr/share/doc/gcc-c++-3.4.5/ChangeLog.egcs /usr/share/man/man1/g++.1.gz so not a good idea to install (probably will fail), unless I remove my current default gcc 4.1.1 first, which I don't want to do. Think I'll stick with a private source build into a custom location. Seems safer. Chris
