Qt4 RPMs for Centos 5

Filed under: Centos,Installation,qt — Tags: , — jfreivald @ 11:03 am

UPDATE; New post for the new packages: http://joseph.freivald.com/linux/2010/06/09/qt-4-6-3-and-qt-creator-1-3-1-1-updates-for-centos-5-5/

UPDATE: Nokia released Qt 4.6.0 and qt-creator 1.3.0 today.  The new RPMs are compiled and stored in the repository.  ‘yum update’ should be sufficient to grab the new ones.  I also changed the directory to reflect Centos 5.4 instead of 5.3.  Let me know of any issues.

Want to get the Qt SDK working on Centos 5.3?

Quick instructions:

rpm -ivh http://software.freivald.com/centos/software.freivald.com-1.0.0-1.noarch.rpm
yum update fontconfig fontconfig-devel qt4 qt4-devel qt4-doc qt4-postgresql qt4-odbc qt4-sqlite qt-creator

Verify that the versions are coming from software.freivald.com and install. 🙂

Longer story:

All of the RPM’s described in this post are in a yum repository that you can access by installing this RPM.  It includes both x86_64 and i386 repositories that are automatically selected based on your architecture.

The first problem: the FcFreeTypeQueryFace problem that is very well described here, with a manual compile and upgrade way around it.  I thought I would go one step further and create an RPM.  Here is what I did:

I started with this source file from fontconfig.org and this SRPM from redhat.com, modified the spec file from the SRPM because of a changed config file location, and created these RPM files for you to install.

The second problem:  the QtSDK is built against several other libraries that are newer than provided with CentOS 5.3.  Rather than update those libraries, I’ve opted to compile RPMs for qt4 and qt-creator for CentOS 5.3. There are all new packages for them in the repository. They upgrade the shipped version (4.2.1) to the new version. They should be binary compatible, since theoretically Qt only breaks binary backwards compatibility on a major revision number change, but I don’t have any real way to test this. Feel free to post any problems you encounter.

The third problem: qt-creator isn’t included with the qt4 source.  I created it as its own package.  ‘yum install qt-creator’ to install it by itself.

Hopefully after installing the repository package, a

yum update

and everything should ‘just work’.

Oh, and feel free to use the ‘joewidgets’ and ‘joewidgets-devel’ packages.  They include some widgets that I use for other projects, primarily a back-port of the KLed widget to QLed that removed KDE dependancies, and a multi-state button with configurable colors for each state.  The ‘devel’ package includes designer plugins that also work in qt-creator.  Source for those are published in the srpms directory.
