    First build the Plug and Paint Plugins example and then the Plug and Paint example itself.

      @SGaist , dear, there is question about plug and paint example. I tried to build pluging on another pc with fresh windows and the same errors with error of make install, Please correct me if I do wrong.

      1. open plug and paing basic tools project
        2, build it succesfully
      2. go to folder with the build and run make install and it returns errors. (compile output)
      C:/Qt/Tools/mingw492_32/bin/../lib/gcc/i686-w64-mingw32/4.9.2/../../../../i686-w64-mingw32/bin/ld.exe: cannot find -lpnp_basictools
      collect2.exe: error: ld returned 1 exit status
      Makefile.Release:94: recipe for target 'release\plugandpaint.exe' failed

      Error while building/deploying project plugandpaint (kit: Desktop Qt 5.5.1 MinGW 32bit)
      When executing step "Make"
      

      am I missing something some steps??

        First build/install the project that can be found in examples/widgets/tools/plugandpaintplugins/and only after that build your Plug And Paint example.

          @SGaist
          what make install shows

          cd basictools\ && ( if not exist Makefile C:\Qt\5.5\mingw492_32\bin\qmake.exe C:\Qt\Examples\Qt-5.5\widgets\tools\plugandpaintplugins\basictools\basictools.pro -spec win32-g++ -o Makefile ) && make -f Makefile install

          I think there is some problems with paths, but I do not understand what is wrong.

              @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.

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

                          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

                              Why Run of plugandpaint in QtCreator may give this message?

                                Because it can't find the plugin files.

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

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