How to add qsvg

**Aceman2000** · 3rd February 2008, 11:44

Problem solved!

I'm not sure what solved it, so here's a list of what I did:

-uninstall Qt, remove any remaining files by hand
-reinstall Qt
-edit the g++ mkspecs (add -static to lflags)
-configure -static -release -no-qt3support -no-exceptions -no-qmake -fast
-make sub-corelib,sub-gui,sub-network,sub-svg, and sub-plugins (maybe I forgot one)

My .pro file's relevant lines are now

QT += svg
QTPLUGIN += qsvg
LIBS += -L$$[QT_INSTALL_PLUGINS]/iconengines
LIBS += $$[QT_INSTALL_PLUGINS]/iconengines/libqsvg.a

With this, my program compiles and shows the icons when run.

Thanks!

Huh? What for? Running configure -static should have taken care of that.

Because this says so

As far as I remember it was required to kill dependency to mingwm10.dll. Notice that -static is added to QMAKE_LFLAGS. All what "configure -static" does is that it adds "CONFIG += static" which is not enough to kill the aforementioned dependency.

It's just for convenience, so that you don't have to add it to your projects. But ok, if J-P says it's "required" then let's agree it is

Heh, but you would have to add it to Qt project as well, wouldn't you?

Only if you didn't want MinGW dependencies. And let's face it, most Windows machines do have that library installed.

I'm afraid I have to disagree with that. Usually you have mingwm10.dll available if and only if you have MinGW installed AND its bin folder added to PATH.

I agree, at first (long time ago) my program didn't even execute (complaining about mingwm10.dll), only when I ran it from a Qt command prompt (which 'fixed' PATH).
