As someone who has a habit of finding issues in my own builds, let
me start with a question or two for Roger:
What version of LFS is this (I think in some earlier posts you were
building on old systems, but maybe I'm mistaken) ?
Do you already have an earlier version of Qt5 installed ?
IFF you have an older version of Qt5, AND it is in /opt/qt5 (or
somewhere else outside /usr and /usr/local), I suggest moving it to
/opt/qt5-some-identifier and NOT putting that in /etc/ld.so.conf.
On a non-kde system, dropping out of Xorg and rerunning startx was
enough to make the old version unused. But in some situations I
guess you might need to reboot.
I had to do that after building 5.12.0 for the first time, and then
discovering that qtwebengine-5.12.0 did not build and falkon was
broken. In the end, I had three versions of /opt/qt5 - the one in
use, the old 5.11 (from a backup), and the broken version with
5.12.0 and webengine from 5.11. Clearly, that takes space - but in
a reasonably large system partition it can be done.
And after all that, have another try at building 5.12.0.
At one time, I tried building Qt5 (and even kde, if I built that) in
/usr, but the book's recommendation to use /opt - plus the way in
which I hide static libs so that I know when they are used (parts of
kde use several, both from Qt and from other parts of kde, and now
webengine needs a static lib as documented in the book) - has made
me give up on that.
