Precondition:
my system is RHEL5.5
and my QT SDK is qt-sdk-linux-x86-opensource-2010.04.bin
Error:
FcFree TypeQuery Face
Solution:
download fontconfig-2.4.2.tar.gz
tar zxvf it and configure and make, but do not make install it.
here is the configure cmd string:
./configure --sysconfdir=/etc --prefix=/usr --mandir=/usr/share/manmy QT SDK is intalled here:
/opt/ins/qt4/qtsdk-2010.04/lib

[root@localhost lib]#
but the
libfontconfig.so.1 in my system is out of date and not valid for QT SDK.
so, I download the newer one and make it.
no need to uninstall previous older one.
just backup it and link the newer one to /usr/lib
/usr/lib

here is the cmd:

/opt/pro/uti/fontconfig/fontconfig-2.4.2/src/.libs/libfontconfig.so.1
and you need to link it to /usr/lib/libfontconfig.so.1
close QT SDK and reboot it to build your project. that's okay.
If you really want to update rpm, just download fontconfig-2.4.2-3.fc7.i386.rpm
and fontconfig-devel-2.4.2-3.fc7.i386.rpm.
install them without dependence check:
rpm -Uvh --nodeps fontconfig-2.4.2-3.fc7.i386.rpm
rpm -Uvh --nodeps fontconfig-devel-2.4.2-3.fc7.i386.rpm
that's all.
Good luck.

Second, How to integrate QT SDK into Eclipse
![](http://www.cppblog.com/images/cppblog_com/jonsenelizee/2010-08-20-010447_1024x699_scrot.png)
Just download qtjambi-eclipse-integration-linux32-4.5.2_01.tar.gz
cd into your eclipse dir and tar xvf it under dropins as me.
/opt/ins/cpp/eclipse/dropins

Good luck.
