Solved 'plugin and paint' example cannot open file "plugin\pnp_basictoolsd.lib" error
-
I am learning from official Qt5.0.2 examples. I have plugandpaint and plugandpaintplugin example copied into my workspace and built them ok. The lib and dll files are created in the right location as expected. But when I run the pluginandpaint example, I got above error. By looking at the directory, the files are there.
Look at the following pro file, I don't know where and what I can add the path:
@#! [0]
QT += widgetsHEADERS = interfaces.h
mainwindow.h
paintarea.h
plugindialog.h
SOURCES = main.cpp
mainwindow.cpp
paintarea.cpp
plugindialog.cppLIBS = -Lplugins -lpnp_basictools
if(!debug_and_release|build_pass):CONFIG(debug, debug|release) {
mac:LIBS = $$member(LIBS, 0) $$member(LIBS, 1)_debug
win32:LIBS = $$member(LIBS, 0) $$member(LIBS, 1)d
}
#! [0]install
target.path = $$[QT_INSTALL_EXAMPLES]/widgets/tools/plugandpaint
INSTALLS += target
@Then I tried "Add Library" from Creator. The 'Internal library' doesn't allow me to add any files. The "External library" added the following into the pro file:
@win32:CONFIG(release, debug|release): LIBS += -L$$PWD/plugins/ -lpnp_basictoolsd
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/plugins/ -lpnp_basictoolsdd
else:unix: LIBS += -L$$PWD/plugins/ -lpnp_basictoolsdINCLUDEPATH += $$PWD/
DEPENDPATH += $$PWD/@After "Clean", "Run qmake" and "Rebuild", I got the same error:
@error: LNK1104: cannot open file 'plugins\pnp_basictoolsd.lib'@
But the folder and file do exist there. That 'plugins' folder is in the same level as the pro file.
Where and how I can config to let the Qt knows the lib needed?
I am using Qt 5.0.2 and windows 7 professional. I didn't change anything on the examples.
EDIT:
No magic, keep playing with it and eventually you will find Creator will wake up and do right thing for you.

"keep playing with it" - strange solution)
this solved for me:- build a .lib from "Plug & Paint Basic Tools Example" which has basictools.pro and basictoolsplugin.cpp
- put this .lib so that "Plug & Paint Example" (which has plugandpaint.pro) can see that .lib
- now you can build&run it
