about compiling in Debian Linux

[rushtosri]

Hi,

I am running Debian Linux

could somebody please tell me how to compile the qt "hello world" program in the tutorial?

I am obviously missing something simple but I can't get g++ to find the library!!

Shri.

Hi,



Try putting the explicit path to the lib directory (and header files if needed) e.g. :



g++ hello.c -o hello.o -I/usr/lib/qt-1.45/include -L/usr/lib/qt-1.45/lib -lqt



or



g++ hello.c -o hello.o -I/usr/lib/qt-2.3.1/include -L/usr/lib/qt-2.3.1/lib -lqt



(depending on version of headers/modules you have)



-I is path the include headers (.h files)

-L is path to qt libs

-l is name of library containg code needed without the 'lib' - e.g. libqt = qt.



Your paths may differ but you get the idea no doubt. You can also set the QTDIR environment variable like :



setenv QTDIR /opt/qt-2.3.1 (whatever is appropriate for debian)
