/opt/qtsdk-2010.02/qt/lib/libQtGui.so: undefined reference to `FcFreeTypeQueryFace'

If you get this error under RHEL or CentOS 5.x: /home/esutton/qtsdk-2010.02/qt/lib/libQtGui.so: undefined reference to `FcFreeTypeQueryFace' collect2: ld returned 1 exit status Apparently libQtGui.so fails trying to use the libfontconfig `FcFreeTypeQueryFace' method. Prior to version 2.4.2 it either did not exist or perhaps the signature was changed in version 2.4.2. Not sure which, but an updated version needs to be installed to: '''/usr/lib/libfontconfig.so.1''' How to Fix Download sources and configure to install where it expects to find it:
cd /usr/src wget
http://fontconfig.org/release/fontconfig-2.4.2.tar.gz
tar -zxf fontconfig-2.4.2.tar.gz
cd fontconfig-2.4.2
./configure -prefix=/usr
make
make install
<- Run as root or use sudo After doing this, you do not need to add the fontconfig library location to your Qt project’s .pro file. LIBS += -L/opt/fontconfig-2.4.2/lib This has worked for me on RHEL 5.3. I hope this helps! -Ed
