Guys, I'm trying to learn how to solve these include errors. At first glance, it looks like the build isn't accepting my: export CMAKE_INCLUDE_PATH=/opt/qt/include:/opt/qt/include/tqt:/opt/trinity/include The error I'm dealing with is: [ 7%] Building CXX object kdialogd3/CMakeFiles/kdialogd3.dir/kdialogd.o cd /home/david/tblds/trinity-app-kgtk-qt3/src/kgtk-qt3/kdialogd3 && /usr/bin/c++ -march=x86-64 -mtune=generic -O2 -pipe -Wnon-virtual-dtor -Wno-long-long -ansi -Wundef -Wcast-align -Wconversion -Wchar-subscripts -Wall -W -Wpointer-arith -Wwrite-strings -Wformat-security -fno-exceptions -fno-check-new -fno-common -O2 -I/home/david/tblds/trinity-app-kgtk-qt3/src/kgtk-qt3 -I/home/david/tblds/trinity-app-kgtk-qt3/src/kgtk-qt3/kdialogd3 -I/home/david/tblds/trinity-app-kgtk-qt3/src/kgtk-qt3/common -I/opt/trinity/include -I/opt/qt/include -o CMakeFiles/kdialogd3.dir/kdialogd.o -c /home/david/tblds/trinity-app-kgtk-qt3/src/kgtk-qt3/kdialogd3/kdialogd.cpp In file included from /home/david/tblds/trinity-app-kgtk-qt3/src/kgtk-qt3/kdialogd3/kdialogd.h:4:0, from /home/david/tblds/trinity-app-kgtk-qt3/src/kgtk-qt3/kdialogd3/kdialogd.cpp:3: /opt/trinity/include/kfile.h:21:19: fatal error: tqdir.h: No such file or directory compilation terminated. I think the short answer is the cmake files have not been tailored to Trinity, but I'm trying to figure out how to do that. The chain of the error seems simple, /opt/trinity/include/kfile.h includes: #include <tqdir.h> which is in /opt/trinity/include/tqt, so in order for it to be seen as a standard <file.h> include instead of a "tqt/file.h" include, the Trinity cmake setup must do something to tell the compiler to look in /opt/trinity/include/tqt as a standard include directory. I thought that was what I was doing with CMAKE_INCLUDE_PATH=.... What else do we need to do in the cmake files? Thanks :) -- David C. Rankin, J.D.,P.E.
