undefined reference to qt_static _plugin

jsulm

@NIXIN Sorry, my post was wrong.
"Link your application with your plugin library using LIBS in the .pro file." - so, using LIBS is correct. But you're using it wrongly, it should be:

LIBS    += -L"/home/uidm9805/Qt Projects/static_plugin_qmake/build/plugin_qmake" -lplugin_qmake

Better to use relative paths, see http://doc.qt.io/qt-5/qtwidgets-tools-plugandpaint-app-example.html

@jsulm I tried using LIBS += the way you suggested, however still it is not working...
getting same errors again

jsulm

@NIXIN Can you show your LIBS line from your pro file?

NIXIN

@jsulm

TEMPLATE = app
QT      += widgets

HEADERS  = interface.h

SOURCES += main.cpp

#LIBS    += "/home/uidm9805/Qt Projects/static_plugin_qmake/build/plugin_qmake/libplugin_qmake.a"

LIBS    += -L"/home/uidm9805/Qt Projects/static_plugin_qmake/build/plugin_qmake" -lplugin_qmake

jsulm

@NIXIN You should check the linker call as you have a space in your path which can cause issues (you should avoid spaces in paths).

NIXIN

@jsulm I tried same thing with this example http://doc.qt.io/qt-5/qtwidgets-tools-plugandpaint-app-example.html and its working fine there

LIBS += "/home/uidm9805/Qt Projects/plugandpaint/build/plugandpaint/plugins/libpnp_basictools.a"

don't know why this project is behaving in odd manner

jsulm

@NIXIN Is your plug-in really located here: /home/uidm9805/Qt Projects/static_plugin_qmake/build/plugin_qmake? And was it build with exact same compiler and Qt version?

NIXIN

@jsulm yes plugin is located in the given path and compiler versions are same

NIXIN

can anybody help me with this issue??

NIXIN

After lot of hit and trial, I got the mistake I was doing

Q_IMPORT_PLUGIN(plugin_qmake)

this line should have the class name of plugin

Q_IMPORT_PLUGIN(PluginQmake)

now it works fine....
