slackernetuk commented 2 months ago

Expected Behavior

A default panel should start under X11

Current Behavior

Cannot load library /usr/lib64/lxqt-panel/libmount.so: (/usr/lib64/lxqt-panel/libmount.so: undefined symbol: _ZN27LXQtPanelPluginConfigDialog16staticMetaObjectE)"
/usr/bin/lxqt-panel: symbol lookup error: /usr/lib64/lxqt-panel/libvolume.so: undefined symbol: _ZNK14PluginSettings5groupEv

Possible Solution

Rebuild LXQt 2.0 in order, no change.

Have you installed solid V6? It's among required packages.

Yes, solid-6.1.0 is installed.

In your build order lxqt-globalkeys is missing, but the panel shouldn't build without it.

Sorry my order list is a bit messy, here is my complete order:

I'll rebuild LXQT, because I forgot to build kguiaddons. And hopefully it will work. :-)

Edit: No luck, lxqt-panel crashed.

The problem is that the plugins don't see the symbols that are defined in the lxqt-panel binary itself. Chances are the linker is not exporting symbols from the binary because it isn't a library. Adding -rdynamic to the linker flags should help.

PR 2053 fixes it.
