Hi everyone!
I've been using Lazarus with Qt5 for quite a while and everything
worked flawlessly, but after a month of break I returned to my
projects and I faced this error. I can't build any of them.
Whatever I wanna build, I'm getting:
Quote/usr/bin/ld: /lib64//libQt5Pas.so: undefined reference to
`QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>)@Qt_5'
I'm using Gentoo Linux, Qt-5.15.5 and Lazarus 2.2.2. As I remember I
recently updated Qt but I don't remember what was the previous
version.

libQt5Pas seems to be where it's supposed to be:
Quote#ls /lib64/libQt5Pas*
/lib64/libQt5Pas.so  /lib64/libQt5Pas.so.1  /lib64/libQt5Pas.so.1.2.9
and it worked like this for months.

I tried to rebuild Lazarus but the result is the same:
Quote$ LCL_PLATFORM="qt5" make clean all
.
.
.
(9015) Linking ../lazarus
/usr/bin/ld: /lib64//libQt5Pas.so: undefined reference to
`QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>)@Qt_5'

I was searching for some newer libQt5Pas version but no luck. I also
tried installing libQt5Pas from pg_overlay but nothing has changed.

Any clue?

Thanks in advance!
