undefined reference to `qt_version_tag'

SGaist

Hi and welcome to devnet,

Do you have the Qt development packages from your distribution installed ?
Are you sure Eclipse is using the correct version of Qt ?

GastonMelo

I solved the qt_version_tag. But how can I uninstall Qt?

SGaist

The one from the installer ? Use the MaintenanceTool you find at the root of your Qt installation.

GastonMelo

I cant find it. I search for MaintenaceTool and cant find it. How do I install Qt? by console:
./qt-unified-linux-x64-3.0.6-online.run. Other way?

@GastonMelo said in undefined reference to `qt_version_tag':

./qt-unified-linux-x64-3.0.6-online.run

If you installed with that installer, you should really have a MaintenanceTool. For me it is in /opt/Qt, but that depends on your installation path.

The directory looks like that:

$ ll /opt/Qt

Nope. My installation folder is /home/user/Qt.

SGaist

And what exactly do you have in there ?

GastonMelo

i can tell you that not the MaintenanceTool. I search all folder (the hiddens too) and I cant find that file.

SGaist

Hence my question: what do you have in that folder ?

GastonMelo

I have this folders:

5.13.0
dist
Docs
Examples
Licenses
Tools

and this files:
components.xml
update.rcc

and the Qt.png icon

@GastonMelo strange. so it seems deleting the whole folder is only possible solution.

Btw: 5.13 is not official released yet (will be in few weeks), so better use 5.12.x for now.
