undefined reference to GMOUSEVMT_OnlyOne

Hi,

I'm facing the following error while building the widget demo.I'm building demo for Linux-Frame buffer.

Please someone help me to resolve it.

.build/obj/GFXLIB/src/ginput/ginput_mouse.o: In function `_gmouseInit':
/home/user/Downloads/ugfx_2.5/src/ginput/ginput_mouse.c:653: undefined reference to `GMOUSEVMT_OnlyOne'
/home/user/Downloads/ugfx_2.5/src/ginput/ginput_mouse.c:654: undefined reference to `GMOUSEVMT_OnlyOne'
collect2: error: ld returned 1 exit status
make: *** [.build/example] Error 1

The Linux-Framebuffer board files only contain drivers & board files for passive display output. They don't contain anything that handles mouse/touch inputs. If your touchscreen/mouse is accessible through the Linux input event system, you can simply use the Linux-Framebuffer-Touch board files which will automatically include the /drivers/ginput/touch/Linux-Event driver.

You can find more information about this here: https://wiki.ugfx.io/index.php/Linux#Touchscreen_.2F_Mouse
And a complete tutorial here: https://wiki.ugfx.io/index.php/Raspberry_Pi

Also, this new Linux-Framebuffer-Touch board file has been added just a few days ago. You might want to click the "Follow" button on the µGFX-Development blog to stay up-to-date about these kind of new things, updates & bug fixes: 

I hope that helps. Let us know if you have any other questions.
