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 += widgets
HEADERS = interfaces.h \
mainwindow.h \
paintarea.h \
plugindialog.h
SOURCES = main.cpp \
mainwindow.cpp \
paintarea.cpp \
plugindialog.cpp
LIBS = -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_basictoolsd
INCLUDEPATH += $$PWD/
DEPENDPATH += $$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.
