my os is win7 64bit ,cpu:core i7

Just run go run demo.go ?

[Razakhel]

Mine doesn't work either. It tells me that gdk_pixbuf_get_pixels with length can't be found in the dynamic links library .

[mattn]

@Eiwhaz What version of gtk do you use?

[Razakhel]

I'm using the 2.22-64bits version, the all-in-one bundle. I tried the 3.X before I saw that you asked for the 2.X for Linux, thus I thought we were needing it as well for Windows (I maybe should have said first that I was trying to get it work on Windows indeed). The 3.X didn't work either, though I don't recall the error messages.

[mattn]

2.22 doesn't have gdk_pixbuf_get_pixels

https://developer.gnome.org/gdk-pixbuf/stable/gdk-pixbuf-The-GdkPixbuf-Structure.html#gdk-pixbuf-get-pixels-with-length

Since 2.26

Same problem here. I first installed using "make example", then tried "go run demo.go", but I get a fatal error:

I have tried some of the other examples, but I get fatal errors on all of them.
