problem compiling with qtopia core 4.2.2
Message 1 in thread
Hi list!
I have a problem compiling applications with qtopia core 4.2.2 on linux.
With qtopia core 4.1.4, everything works correctly.
I configured qtopia core as follows
./configure --prefix=/usr/local/Trolltech/QtopiaCore-4.2.2-x86 -embedded
x86 -debug-and-release -no-qt3support -pch -qvfb
it installs fine and I am able to start the demos. But if I compile one of
my applications, I get the following linker errors:
g++ -Wl,-rpath,/usr/local/Trolltech/QtopiaCore-4.2.2-x86/lib -o

What did I do wrong? Do I miss some of the enviroment-variables?
I use gentoo linux with kde 3.5, kernel 2.6.18 and gcc 4.1.1
Thanks in advance for any hints!
Bye,
Andy

I believe that the application also needs to link against libQtNetwork.so
as well, but this should be handled automatically if you are using qmake.
You may be able to work around the issue by adding
QT += network
to your application's .pro file, but I'd also keep looking for a solution
to the underlying problem, too.
