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

Kofr

@SGaist I have never faced with such a problem....
yes, I do have space....
If I delete all files from target directory C:\Qt\Examples\Qt-5.5\widgets\tools\plugandpaint\plugins and run make install I get the listing as in my previous post with errors of gnu make, but in the target directory will be files:

15.03.2016  21:50            32 922 libpnp_basictools.a
15.03.2016  21:50             2 216 libpnp_extrafilters.a
15.03.2016  21:50            23 552 pnp_extrafilters.dll

however Plug and Paint example is not being compiled, still cannot find -lpnp_basictools
Please show your make install output and what files in target directory.

SGaist

Are you doing it from the command line or Qt Creator ?

Kofr

@SGaist building plugins with qt creator, installing by make install

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 ?

Kofr

@SGaist said:

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.

Kofr

@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>          .
17.03.2016  18:22    <DIR>          ..
17.03.2016  20:58            32 706 libpnp_basictools.a
17.03.2016  02:38           920 206 libpnp_basictoolsd.a
17.03.2016  02:34             2 216 libpnp_extrafilters.a
17.03.2016  18:22             2 226 libpnp_extrafiltersd.a
17.03.2016  20:58            23 552 pnp_extrafilters.dll
17.03.2016  18:22           824 956 pnp_extrafiltersd.dll

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.
