Another Linux build issue

[Joseph Newing]

Still trying to build libqxt on linux using Qt5, this is using the latest master ec51438

compiling x11/qxtapplication_x11.cpp
In file included from x11/qxtapplication_x11.cpp:33:0:

[Arkadiusz Piekarz]

If you look at qxtapplication.h, it says:

// native event filter support is not required for Qt5 because Qt5
// QCoreApplication already supports installation of native event filters

Function void removeNativeEventFilter(QxtNativeEventFilter* filter) is defined only for Qt lower than 5, so I think we can put similar #ifdefs around qxtApp->removeNativeEventFilter(this) in QxtNativeEventFilter destructor.

There are more compilation errors related to X11 and QPA, code should be changed to use a new class QxtX11Data, currently in qxtglobalshortcut.cpp (btw that class should be moved to separate file).

This issue is still there as of:

$ git show commit 9068e83def488d9e3bcdb734cf242ce64c024214 Merge: 1726032 70c2c0f Author: Arvid Picciani [e-mail] Date: Wed Oct 23 12:38:31 2013 +0200

I'm using Qt5.1.1 on Ubuntu 13.10 64_bit Linux.

You can compile this against Qt5.2.0 using the -qws switch in ./configure. This isn't a solution, but if you don't need the X11 related parts (I only use the JSON parser and the rpc functions), then it is a workaround for now.

Without the -qws switch I get the same issue as above on the latest MASTER commit.

any progress on this?
