I want to learn this example about working with plugins but I am getting:-1: error: cannot find -lpnp_basictoolsin issues window.
I try to build https://doc.qt.io/qt-5/qtwidgets-tools-plugandpaintplugins-basictools-example.html assuming that this Lib is needed, but when I try tomake installthis plugin I get errors of GNU Makemake -f Makefile.Release install make[1]: Entering directory `C:/Qt/Examples/Qt-5.5/widgets/tools/plugandpaintplugins/build-basictools-Desktop_Qt_5_5_1_MinGW_32bit-Release' copy /y ..\..\plugandpaint\plugins\libpnp_basictools.a C:\Qt\Examples\Qt-5.5\widgets\tools\plugandpaint\plugins\libpnp_basictools.a ЌҐў®§¬®¦® бЄ®ЇЁа®ў вм д ©« Ї®ўҐае б ¬®Ј® ᥡп. ‘Є®ЇЁа®ў ® д ©«®ў: 0. make[1]: Leaving directory `C:/Qt/Examples/Qt-5.5/widgets/tools/plugandpaintplugins/build-basictools-Desktop_Qt_5_5_1_MinGW_32bit-Release'what problem it might be?

Hi,
What is that error message saying ?
-
impossible to copy files over existing. files copied: 0but if I take away existing:

Looks a bit like a permission issue
-
Yes, I do.
Did you first build the Plug and Paint plugins ?
-
-
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.- open plug and paing basic tools project
2, build it succesfully - go to folder with the build and run
make installand it returns errors. (compile output)

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

-
Do you have enough space left ?
-
@SGaist I have never faced with such a problem....
yes, I do have space....
If I delete all files from target directoryC:\Qt\Examples\Qt-5.5\widgets\tools\plugandpaint\pluginsand runmake installI 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.dllhowever Plug and Paint example is not being compiled, still
cannot find -lpnp_basictools
Please show yourmake installoutput and what files in target directory. -
Are you doing it from the command line or Qt Creator ?
-
Where are you calling make install ?
-
Which cmd ?
-
IIRC you should have a MinGW ready command line shortcut in the Qt Start menu entry.
