QT5 LNet installation error: Forward declaration not solved #7

Open alanphys opened 4 years ago

alanphys commented 4 years ago

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 {$ifdef LCLQT5} {$i lclgtkeventer.inc} // identical code ;) {$endif} before end statement in lclnet.pas

Regards Alan

Hey, I think the preprocessor ifdefs changed in newer lazarus and need to be updated. You need to use the QT "lcl" eventer for this tho otherwise it won't work as the main "event loop" won't connect.

I find it interesting that the gtk one worked for you.

Yes, the new version defines LCLQT5. I'm not seeing an lclqteventer.inc. I just copied your existing LCLQT declaration which uses the lclgtkeventer.inc.

So far everything seems to be running OK, but I am only using the TLHTTPServer component. Regards Alan
