Problem
Trying to install lnet in Lazarus from the online package manager and
from git gives

lclnet.pas(45,15) Error: Forward declaration not solved
"HandleIgnoreError(TLHandle);"
lclnet.pas(46,15) Error: Forward declaration not solved
"HandleIgnoreWrite(TLHandle);"
lclnet.pas(47,15) Error: Forward declaration not solved
"HandleIgnoreRead(TLHandle);"
lclnet.pas(48,15) Error: Forward declaration not solved
"InternalUnplugHandle(TLHandle);"
lclnet.pas(50,15) Error: Forward declaration not solved
"HandleEvents(Int64;LongWord);"
lclnet.pas(58,14) Error: Forward declaration not solved
"AddHandle(TLHandle):Boolean;"

System
Fedora 30
KDE 5/QT 5.12.4
Lazarus 2.0.6
LNet 0.66

Cause
QT5 not defined in lclnet.pas

Workaround
Add
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i {$ifdef
LCLQT5}{$i lclgtkeventer.inc} // identical code {$endif} 
before end statement in lclnet.pas

I have listed this as an issue on the GitHub site:
