Hi,
I recently upgraded to Ubuntu 11.10 and experienced problems installing ROOT. The forum gave some answers how to configure and compile, which worked fine, but I am also in need for the QT support for an online displays. This is what I did:
./configure --enable-roofit --enable-minuit2 --enable-builtin-freetype --enable-qt
make -j2 -k LDFLAGS=“-Wl,–no-as-needed”
It builds ROOT just fine including the libGQt.so library needed for the QT implementation. So I cleaned and tried to compile my QT program:
make distclean
make clean
qmake
make
I am now getting the following error:
/home/philip/bin/root/lib/libGQt.so: undefined reference to TRint::TRint(char const*, int*, char**, void*, int, bool)' /home/philip/bin/root/lib/libGQt.so: undefined reference to TCanvas::TCanvas(char const*, int, int, int)’
/home/philip/bin/root/lib/libGQt.so: undefined reference to `TImage::Create()’
Does anybody have an idea what is going wrong?
Thanks a lot,
Philip
