Qt communication error
I am setting up qt-x11 with the following parameters
./configure -prefix / iTalk / qtx11 -prefix-install -bindir / iTalk / qtx11-install / bin -libdir / iTalk / qtx11-install / lib -docdir / iTalk / qtx11-install / doc -headerdir / iTalk / qtx11- install / include -datadir / iTalk / qtx11-install / data -examplesdir / iTalk / qtx11-install / examples -demosdir / iTalk / qtx11-install / demos -debug.
Now I am getting the following errors on Fedora Core 6.
Could you tell me where is the problem?

You are missing references to FontConfig .
./configure
accepts a radio button -no-fontconfig
, but it would be better to figure out why ./configure
doesn't include the FontConfig correctly. (The logs you've posted aren't far back enough to even figure out what a bad link means.)

This is similar to a known issue on Red Hat based systems and the older version of FontConfig they are using. There are good troubleshooting instructions at http://theitdepartment.wordpress.com/2009/03/15/centos-qt-fcfreetypequeryface/ .

The thing is, the version of fontconfig provided by the red hat is too old and the symbol is missing (I read that it is the minor version number which is low and that causes the missing symbol). If you just update fontconfig it doesn't work for me because it finds the old version, but when I change the makefile to reference the new libfontconfig.so it works directly. In your .pro file add the following line: LIB + = / path / to / your / NewFontConfiglib.so.XX Also, simple yum update doesn't work, it says package is updated, I read the post that shows how to add newer. Later I decided that I needed to create a stand-alone application, so I started building a static version of Qt and got into the same problem ..... I was not sure how to change this makefile, although I came across this post.so hopefully this will work. Take a look at this post:CentOS 5.2 + Qt 4.5 + FcFreeTypeQueryFace
