Other than that, I have no ideas - unfortunately the qwenview releases don't have any information on what changed, and I could not find any Release Notes. A couple of comments. First, gwenview works fine for me on a BLFS-10.0 system. Second, you can check the symbols in a binary with the nm utility. In this case I ran nm /opt/kf5/bin/gwenview|grep ByteArray|grep Plug and got no hits, so some library is asking for the OP's zombie symbol. I'm not going to search the 151 libraries that ldd reports for gwenview. I do not know the OP's setup, but one reason we suggest putting qt, kf5, and xorg into /opt is to make it easier to rebuild components and not mix old and new versions in the /usr hierarchy. -- Bruce -- http://lists.linuxfromscratch.org/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page

Upon researching it seems cfisio is apart of that which is installed at 3.19 I'm at a loss lol On Mon, Sep 14, 2020, 8:18 AM Elias Rudberg wrote: > On Mon, 2020-09-14 at 07:09 -0400, Linux Lover via blfs-support wrote: > > Followed instructions > > http://www.linuxfromscratch.org/blfs/view/svn/kde/gwenview5.html > > > > Compiled just fine, however upon launching I get an error > > > > gwenview: symbol lookup error: > > gwenview: undefined symbol: > > _ZNK10FitsPlugin12capabilitiesEP9QIODeviceRK10QByteArray > > > > Any ideas?
