I can confirm that this helps - thanks a lot! > Then there's > still some error (declaration of 'float t' shadows template parameter), but > I don't know how to fix that one. I think I fixed this by removing the code copy of CImg.h and using the Debian packaged version instead. But the QDebug issue came back and may be I need another trick to tweak src/qtbeads/CMakeLists.txt that the -I directive is inserted properly: ... cd /build/beads-1.1.13+dfsg/obj-x86_64-linux-gnu/src/qtbeads && /usr/bin/c++ -DHAVE_PTHREAD_H -DQT_NO_DEBUG_OUTPUT -I/build/beads-1.1.13+dfsg/src/X11_INCLUDE_DIR -I/build/beads-1.1.13+dfsg In file included from /build/beads-1.1.13+dfsg/src/images/imageIntensity.cpp:1:0: /build/beads-1.1.13+dfsg/src/images/imageIntensity.h:4:10: fatal error: QDebug: No such file or directory #include <QDebug> ^~~~~~~~ compilation terminated. src/qtbeads/CMakeFiles/qtbeads.dir/build.make:145: recipe for target 'src/qtbeads/CMakeFiles/qtbeads.dir/__/images/imageIntensity.cpp.o' failed make[3]: *** [src/qtbeads/CMakeFiles/qtbeads.dir/__/images/imageIntensity.cpp.o] Error 1 ... I have the feeling that this might be the last hint I need. ;-) Thanks for all your help Andreas. [1] https://anonscm.debian.org/git/debian-med/beads.git -- http://fam-tille.de
