plugin example app launch problem :-1: error: cannot find -lpnp_basictools

SGaist

Where are you calling make install ?

Kofr

@SGaist cmd

cd C:\Qt\Examples\Qt-5.5\widgets\tools\build-plugandpaintplugins-Desktop_Qt_5_5_1_MinGW_32bit-Release
make install

SGaist

Which cmd ?

WINDOWS Command prompt
is it wrong way to use external gnu make?

SGaist

IIRC you should have a MinGW ready command line shortcut in the Qt Start menu entry.

@SGaist I instaled Qt 5.6, now I install plugins succesfully but it does not matter as all plugins already built stays in Plug & Paint example folder /plugins.
However when building Plug & Paint example is says :-1: error: cannot find -lpnp_basictools
even if /plugins contains

17.03.2016  18:22    <DIR>          .

Why Run of plugandpaint in QtCreator may give this message?

SGaist

Because it can't find the plugin files.

One thing you could to is add the path to them to the example .pro file.

Kofr

@SGaist great thx for you for assist.
I change default .pro config

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
}

to

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/plugins/ -lpnp_basictools
else:win32:CONFIG(debug, debug|release): LIBS += -L$$PWD/plugins/ -lpnp_basictoolsd
else:unix: LIBS += -L$$PWD/plugins/ -lpnp_basictools

INCLUDEPATH += $$PWD/plugins
DEPENDPATH += $$PWD/plugins

win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/plugins/libpnp_basictools.a
else:win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/plugins/libpnp_basictoolsd.a
else:win32:!win32-g++:CONFIG(release, debug|release): PRE_TARGETDEPS += $$PWD/plugins/pnp_basictools.lib
else:win32:!win32-g++:CONFIG(debug, debug|release): PRE_TARGETDEPS += $$PWD/plugins/pnp_basictoolsd.lib
else:unix: PRE_TARGETDEPS += $$PWD/plugins/libpnp_basictools.a

generated with QtCreator tool, and it works
I am not really sure why it works when default code did not.

I have the same problem running on Ubuntu, on windows 8 otherwise i have no problems :\ , if i build first the plugin and after the application it works just fine
