Serghei, After building qt3 in a pristine build environment, I thought I would build the rest of trinity there while I had the chance. So far, the dependencies have built without issue: trinity-qt3-3.3.8c-1-x86_64.pkg.tar.xz trinity-pyqt3-3.18.1-9-x86_64.pkg.tar.xz (poppler-qt3 still fails) trinity-dbus-1-qt3-0.9-7.2-x86_64.pkg.tar.xz trinity-tqtinterface-1230411-1-x86_64.pkg.tar.xz Building arts, I have run into another .moc file that isn't generated. This time it is qiomanager_p.moc. The build gets to 100% and then dies with: [100%] Building CXX object qtmcop/CMakeFiles/qtmcop-shared.dir/qiomanager.cc.o cd /build/src/build/qtmcop && /usr/bin/c++ -Dqtmcop_shared_EXPORTS -DHAVE_CONFIG_H -DQT_NO_ASCII_CAST -DQT_CLEAN_NAMESPACE -DQT_NO_STL -DQT_NO_COMPAT -DQT_NO_TRANSLATION -DQT_THREAD_SUPPORT -D_REENTRANT -march=x86-64 -mtune=generic -O2 -pipe -fPIC -I/opt/qt/include -I/opt/qt/include/tqt -I/build/src/build/qtmcop -I/build/src/build/mcop -I/build/src/arts/mcop -include tqt.h -o CMakeFiles/qtmcop-shared.dir/qiomanager.cc.o -c /build/src/arts/qtmcop/qiomanager.cc /build/src/arts/qtmcop/qiomanager.cc:299:28: fatal error: qiomanager_p.moc: No such file or directory compilation terminated. make[2]: *** [qtmcop/CMakeFiles/qtmcop-shared.dir/qiomanager.cc.o] Error 1 make[2]: Leaving directory `/build/src/build' make[1]: *** [qtmcop/CMakeFiles/qtmcop-shared.dir/all] Error 2 make[1]: Leaving directory `/build/src/build' make: *** [all] Error 2 ==> ERROR: A failure occurred in build(). Aborting... Checking the build directory -- no qiomanager_p.moc was every generated. Could you take a look and see if this is like the kdevelop issue :) -- David C. Rankin, J.D.,P.E.
