Non Qt application linking Qt library
-
Hello,
I have a Qt based library. And I want to link with non Qt application.
When I link it, the linkers get mad about Qt libraries. It expects me to link Qt libraries as well.
Is this an expected behaviour?
Can I not just link only the library I want?
Thanks,

Could it be possible you share your Qt library project file? I guess your library will depend at least on Qt Core

Hi,
Here is the pro file content.
QT += core gui greaterThan(QT_MAJOR_VERSION, 4): QT += widgets TARGET = uicore TEMPLATE = lib CONFIG += staticlib # Find the built application here.. DESTDIR = ../lib
Yes, as you mentioned, my library depends on Qt Core and Qt Gui.
I understand that my library needs these Qt libraries.
But, I am trying to avoid linking Qt libraries for the non Qt application.

I understand that for 'staticlib' to work, you first have to build Qt statically. You may want to take a look at this post.
And please also consider that using Qt statically is very likely that require a commercial license for Qt. There's much debate about LGPL and static linking, you may need some legal advice in that case. I guess this post is a good starting point to understand the possible cases
