Description
im trying to build qtcreator 8.0.1 on NixOS Linux
the challenge with NixOS Linux: most files are in the /nix/store prefix, not in the /usr prefix, so maybe i need to patch some file paths in qtcreator
when i start qtcreator, many plugins fail to load
finally, the QmlProjectManager plugin causes a segfault
how can i get debug output from qtcreator plugins? i tried
QT_LOGGING_RULES='*.debug=true' qtcreator QT_LOGGING_RULES='default.debug=true' qtcreator
only *.debug=true increases the debug level, but i dont see debug output from plugins
i added some debug prints to qt-creator-opensource-src-8.0.1/src/libs/extensionsystem/pluginmanager.cpp
Utils::reverseForeach(queue, [this](PluginSpec *spec) {
loadPlugin(spec, PluginSpec::Running);
if (spec->state() == PluginSpec::Running) {
delayedInitializeQueue.push(spec);
} else {
// Plugin initialization failed, so cleanup after it
qDebug() << "PluginManagerPrivate::loadPlugins spec" << spec << spec->name() << spec->version() << "spec->d->kill()";
spec->d->kill();
}
});
here are the plugins that fail to load:
PluginManagerPrivate::loadPlugins spec 0x15bb620 "Welcome" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x15ab540 "WebAssembly" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x15adae0 "Valgrind" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x1563a70 "UpdateInfo" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x153f570 "Todo" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x1588d10 "TaskList" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x1604950 "Subversion" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x159c6b0 "StudioWelcome" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x159cc70 "SilverSearcher" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x15a0fb0 "SerialTerminal" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x1591a00 "ScxmlEditor" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x1522870 "Qnx" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x15433a0 "QmlProfiler" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x156d020 "QmlDesigner" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x1533e90 "QmlPreview" "8.0.1" spec->d->kill() PluginManagerPrivate::loadPlugins spec 0x1583090 "QmlProjectManager" "8.0.1" spec->d->kill() Segmentation fault (core dumped)
