Process
From http://redmine.emweb.be/boards/2/topics/1057 :
Richel, There is/was a bug in ubuntu's patches to gcc causing the compiler to crash on Wt: https://bugs.launchpad.net/ubuntu/+source/gcc-4.4/+bug/647597 Unfortunately, the latest Wt release does not compile well on Ubuntu. You have two options: If you use the git version of Wt, this buggy compiler will be detected and a work-around is used. Upgrade your compiler BR, Wim.
Solution/workaround
Add the following lines to the project file:
LIBS += -L/usr/lib -lwt -lwthttp QMAKE_CXXFLAGS += -DNDEBUG
This results in the following complete project file:
