Well I suppose it all depends on which part of the docos is correct. :-) Quoting:- http://distcc.samba.org/faq.html#mixed-gcc Different gcc versions? if the host machine is using gcc 3.2, can the other machines use an older version of gcc ? 2.9.x for example ? distcc doesn't care. However, in some circumstances, particularly for C++, gcc object files compiled with one version of gcc are not compatible with those compiled by another. This is true even if they are built on the same machine. It is usually best to make sure that every compiler name maps to a reasonably similar version on every machine. You can either make sure that gcc is the same everywhere, or use a version-qualified compiler name, such as gcc-3.2 or i386-redhat-linux-gcc-3.2.2. Which seems to make good sense to me. So all the helpers / installer need to have the same version of gcc. The 'gcc --version' command tels me I have the current one for Gentoo, it is "gcc (GCC) 3.2.2" I would therefore be, imho, a very good idea it all the machines used in the cluster had that version installed. -- C.
