I just synced my local copy of the lyx repo and compilation now fails with Qt related issues.
Here is the first error: [ 4%] Building CXX object src/support/CMakeFiles/support.dir/Systemcall.cpp.o cd /home/stefano/builds/lyx-devel/lyx/build/src/support && /usr/bin/c++ -DQT_CORE_LIB -Wall -Wunused-parameter -fno-strict-aliasing -Wall -Wunused-parameter -fno-strict-aliasing -O0 -g3 -D_DEBUG -fPIC -I/home/stefano/builds/lyx-devel/lyx/build -I/home/stefano/builds/lyx-devel/lyx/src -I/home/stefano/builds/lyx-devel/lyx/boost -I/home/stefano/builds/lyx-devel/lyx/src/support -I/home/stefano/builds/lyx-devel/lyx/build/src/support -I/home/stefano/builds/lyx-devel/lyx/src/support/mythes -I/usr/include/qt -I/usr/include/qt/QtCore -I/usr/lib/qt/mkspecs/linux-g++ -DBOOST_USER_CONFIG="<config.h>" -o CMakeFiles/support.dir/Systemcall.cpp.o -c /home/stefano/builds/lyx-devel/lyx/src/support/Systemcall.cpp In file included from /home/stefano/builds/lyx-devel/lyx/src/support/Systemcall.cpp:631:0: /home/stefano/builds/lyx-devel/lyx/src/support/moc_SystemcallPrivate.cpp:13:2: error: #error "This file was generated using the moc from 4.8.5. It" #error "This file was generated using the moc from 4.8.5. It" Isn't the build process still relying on Qt 4? The cmake build comes preset to use the moc from version 4 (Qt 4.8.5) (it looks in /usr/lib/bin/qt4/moc). Or perhaps is my system to blame? Arch defaults to QT5.
