Qt3 Installation on Ubuntu 7.04

[jflowers]

I am trying to install qt3 version 3.3.8 from source code because a program I want to install requires Qt3. After unpacking the files I run configure and everything appears fine. When I run make the following error occurs:

elease-shared/moc_qmotifstyle.o -L/usr/X11R6/lib -lXext -lX11 -lm -ldl
/usr/bin/ld: cannot find -lXext
collect2: ld returned 1 exit status
make[2]: *** [../lib/libqt.so.3.3.8] Error 1
make[2]: Leaving directory `/usr/local/qt/src'
make[1]: *** [sub-src] Error 2
make[1]: Leaving directory `/usr/local/qt'
make: *** [init] Error 2

I can not figure out what is wrong. I appreciate your help.

Try installing libxext-dev:

sudo apt-get install libxext-dev

I'd suggest you do the same with Qt 3 (install packages libqt3-* and qt3-* instead of compiling it by hand).
