Qxt with Qt5.0 MingW: qtAddLibrary() is deprecated. Use qtAddModule() or QT+= instead

[ujwala]

Hi,

I am currently using QT 4.8 and MingW compiler for my application. I am using third party libraries (Qxt & QWT). Now I want to port our application to Qt5. Qxt library is successfully build.

Steps followed for building Qxt:

qmake
mingw32-make
mingw32-make install

qmake
mingw32-make
mingw32-make install

To copy to clipboard, switch view to plain text mode 

qxt.prf and qxtvars.prf file are copied to C:\Qt\Qt5.0.2\5.0.2\mingw47_32\mkspecs\features

In application's .pro file I have mentioned

CONFIG  += qxt 
QXT     += core gui

CONFIG  += qxt 
QXT     += core gui

To copy to clipboard, switch view to plain text mode 

When I compiled it I am getting the errors

Project WARNING: qtAddLibrary() is deprecated. Use qtAddModule() or QT+= instead.
Project ERROR: No module matching library 'QxtGui' found.

Project WARNING: qtAddLibrary() is deprecated. Use qtAddModule() or QT+= instead.
Project ERROR: No module matching library 'QxtGui' found.

Could you please guide me resolving this issue?

Thanks in advance.

QT += qxt 
QXT     += core gui

QT += qxt 
QXT     += core gui

I expect the CONFIG line is not required.

Thanks Chris.

I tried your solution but getting following error:

QT += qxt
QXT     += core gui

QT += qxt
QXT     += core gui

Then qxt.prf is not in the folder that the version of qmake you are using is looking. It should have been put in the correct place (for the version of Qt that owned the qmake you used) automatically when you ran "mingw32-make install" during the Qxt build.

Edit: Execute:

qmake -query

qmake -query

and look for the QMAKE_MKSPECS entry. The "features" folder should be immediately under that folder and contain qxt.prf.

Hi Chris,

I tried qmake -query command I got following output where QMAKE_MKSPECS entry was not present

After compilation I got following error:
