I'm trying to install the kde-frameworks from the BLFS book and when trying to install the kcodecs package I get this error:

/opt/qt5/bin/lconvert: error while loading shared libraries: libQt5Xml.so.5: cannot open shared object file: No such file or directory
make[2]: *** [CMakeFiles/translations_99.dir/build.make:61: zh_HK/kcodecs5_qt.qm] Error 127
make[1]: *** [CMakeFiles/Makefile2:68: CMakeFiles/translations_99.dir/all] Error 2
make: *** [Makefile:130: all] Error 2

I know that it is a problem with lconvert not finding libQt5Xml.so.5 but when I checked /opt/qt5/lib/ libQt5Xml.so.5 was present I also tried "export LD_LIBRARY_PATH=/opt/qt54/lib" but this didn't solve the problem.

If anyone could help that would be much appreciated. Thanks.

Try typing...

And see if it's in the default search path. If it's not, you need to go back and add it to ld.so.conf or as a file in ld.so.conf.d.

Thanks that solved that problem but after it gets past this I get this error:
/opt/qt5/bin/uic: relocation error: /opt/qt5/bin/uic: symbol qt_hash_seed, version Qt_5 not defined in file libQt5Core.so.5 with link time reference
Sorry this is my first time building a desktop interface with LFS.
Thanks for any help.

You seem to have two different Qt5 versions on your system, with one being in ld.so.conf, other being referenced in PATH.

Is there a way I can work around or remove a version?

Just remove references to it from /etc/ld.so.conf and /etc/profile.d, or fix them to reference newest one, only.
