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

SGaist · 15 Mar 2016, 21:00

Where are you calling make install ?

Kofr · S SGaist 15 Mar 2016, 20:57

@SGaist cmd

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

SGaist · 15 Mar 2016, 23:11

Which cmd ?

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

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>          .
17.03.2016  18:22    <DIR>          ..

17.03.2016  18:22           824 956 pnp_extrafiltersd.dll

Why Run of plugandpaint in QtCreator may give this message?

SGaist · 19 Mar 2016, 19:34

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 · S SGaist 18 Mar 2016, 21:59

@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.
