Plugin cannot be loaded

[HowardWhile]

Hi there,
When I import the plugin and restart qt creator, I got an error message like this...

/home/user/.local/share/data/QtProject/qtcreator/plugins/9.0.1/lib/qtcreator/plugins/libROSProjectManager.so: Cannot load library /home/user/.local/share/data/QtProject/qtcreator/plugins/9.0.1/lib/qtcreator/plugins/libROSProjectManager.so: (/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by /home/user/.local/share/data/QtProject/qtcreator/plugins/9.0.1/lib/qtcreator/plugins/libROSProjectManager.so))

This is my system infomation
Ubuntu 20.04
Qt Creator 9.0.1
ros_qtc_plugin 9.0

I have tried below versions and only ros_qtc_plugin 9.0 have problem.

• Qt Creator 6.0.2 + ros_qtc_plugin 0.5.0
• Qt Creator 7.0.2 + ros_qtc_plugin 0.6.0
• Qt Creator 8.0.2 + ros_qtc_plugin 8.1
• Qt Creator 9.0.1 + ros_qtc_plugin 9.0

Maybe I have to make & install GLIBC or update my ubuntu?

I assume you use the "official" binary distribution of Qt Creator installed by the Qt installer and the plugin from the binary release artefacts?

The problem is here version `GLIBC_2.32' not found, which is probably caused by the different systems where Qt Creator and the plugin are compiled. The binary distribution of the plugin is compiled on ubuntu-latest, which is Ubuntu 22.04 at the moment.

I have to look into how to resolve this problem. This is possible since the official binary Qt Creator distribution also works on different Linux distributions.

In the meantime, I suggest you use the Qt Creator snap package which contains Qt Creator and a compatible plugin.

Thanks for your advice.

Now I use the following environment:
Ubuntu 22.04
Qt Creator 9.0.1
ros_qtc_plugin 9.0

Can be used normally~

I downgraded the Ubuntu version in the CI pipeline (#477). If you still want to use the latest version from the online installer you can try the Linux build artefact from that PR.

There will be a new release once this is merged and you will be able to use the official installation instructions again.
