Hi, Running autogen.sh&&./configure --enable-mpqc --enable-mopac2&&make fails for me (gcc-3.4.5, mpqc-2.3.0). Attached patch fixes the problem. Note that the new PrefixKeyVal constructor synthax was already present in mpqc-2.0.0. Cheers, Jean -------------- next part -------------- A non-text attachment was scrubbed...
