arts 3.5.12 FTBFS

I don't know what happened. I modified my build scripts to install Trinity in /opt/trinity. I was planning to install Trinity alongside 3.5.10, which is installed in /usr. This is part of my preparation for building on newer Slackware systems. Here is the tail end of the build log: ====================================== (cd .libs && rm -f libgmcop.la && ln -s ../libgmcop.la libgmcop.la) make[2]: Leaving directory `/dev/shm/dependencies/arts/gmcop' Making all in qtmcop make[2]: Entering directory `/dev/shm/dependencies/arts/qtmcop' /usr/lib/qt/bin/moc ./qiomanager_p.h qiomanager_p.moc Qt meta object compiler moc: Too many input files specified Usage: moc [options] <header-file> -o file Write output to file rather than stdout -f[file] Force #include, optional file name -p path Path prefix for included file -i Do not generate an #include statement -k Do not stop on errors -nw Do not display warnings -v Display version of moc make[2]: *** [qiomanager_p.moc] Error 1 make[2]: Leaving directory `/dev/shm/dependencies/arts/qtmcop' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/dev/shm/dependencies/arts' make: *** [all] Error 2 ====================================== Several days ago I built 3.5.12 with no failures. So I did something wrong, but I don't know what. This is a repeatable failure. I checked that I have qt-3.3.8b installed and not 3.3.8c. Automake is the correct version. tqtinterface-3.5.12 builds without errors and is installed in /usr. Thanks. Darrell
