AW: [mythtv-users] Compiling error on SuSE 8.1 with QT3.3.0

[Philippe C. Cattin]

This is what worked for me on SuSE 8.2 & 9.0. This approach needs no 
fiddeling around with makefiles!

1. get the newest qt3.3 (don't use the 3.3beta as several things won't 
work in myth with the beta version).

   wget ftp://ftp.trolltech.com/qt/source/qt-x11-free-3.3.0.tar.bz2

2. unpack it

    tar -jxf qt-x11-free-3.3.0.tar.bz2

3. cd qt-x11-free-3.3.0

4. ./configure -prefix /usr/local/qt3.3 -qt-gif -thread -qt-sql-mysql 
-I/usr/include/mysql

   I prefer installing the new Qt in /usr/local/qt3.3. the -I is needed 
so that the compiler finds all the header files.

5. make

6. su
    [passwort]

7. make install

at this point you have the newest version of Qt installed in 
/usr/local/qt3.3 and all that is left to do is changing the environment 
variables. since I use tcsh I change it in ~/.tcshrc

   setenv QTDIR /usr/local/qt3.3
   setenv PATH $PATH':$QTDIR/bin'

then make shure you use the new version of Qt during compilation

   source ~/.tcshrc

after a make distclean, ./configure and make in your mythtv everything 
should work as expected.

to ensure that your binaries are realy using the new Qt library you can 
check it with ldd, e.g.:

   ldd /usr/local/lib/mythtv/plugins/libmythmusic.so | grep -i Qt

regards, Philippe
