Hello. I tried to work hello-ktx sample according to README in this project. But it doesn't work and output this error.

My os version is CentOS Linux release 7.6.1810 (Core)

Please give me a hint. Thanks

Maybe not documented here, but documented in upstream libui: https://github.com/andlabs/libui/blob/master/README.md#runtime-requirements Linux version requires GTK+ 3.10 or newer

If it is installed - what is output of pkg-config --libs gtk3 ?

komkomh commented 5 years ago

Hello

Thank you your quick response. I checked my gtk3 version.

pkg-config --modversion gtk+-3.0

3.22.30

pkg-config --libs gtk+-3.0

-lgtk-3 -lgdk-3 -latk-1.0 -lgio-2.0 -lpangocairo-1.0 -lgdk_pixbuf-2.0 -lcairo-gobject -lpango-1.0 -lcairo -lgobject-2.0 -lglib-2.0

Ok, it's installed properly. Well, now - where is it installed on CentOS? If - I can guess - in /usr/lib64 - please try add it to library path, and rebuild:

Thank you! I was able to solve the problem. I'm sorry for the basic questions.

msink commented 5 years ago

So -L/usr/lib64 helped on CentOS? If yes - I'll add it to next published version.

komkomh commented 5 years ago

Yes, I found gtk3 in -L/usr/lib64
