Can't make the gtk3 version work with latest CEF

[antoyo]

Hi.
I'm trying to run the linux gtk3 example, but I get a blank window.
When I'm trying with latest cef (with the update to the version file), here's the output:

gcc -std=c99 -Wall -Werror -o Release/cefcapi-gtk3 -I. -I.. -Wl,-rpath,. -L./Release examples/main_linux.c -lX11 -lcef `pkg-config --libs --cflags gtk+-3.0`
cd Release/ && ./cefcapi-gtk3 && cd ../

When I try with the version specified in the readme, I get this error:

(cefcapi-gtk3:4837): Gtk-ERROR **: 13:17:04.138: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported

(The gtk2 version works fine with the older cef version.)

I'm on ArchLinux and use gtk+ 3.24.

Thanks for your help.

Only branch 3202 was tested as specified in README. You have to build CEF from sources with "use_gtk3=true" GN define to use GTK 3.

Update: FYI, latest version of CEF works with any version of GTK, so that define is not required.

Why don't you write the steps or command to make that happen ?

@vipertecpro See https://bitbucket.org/chromiumembedded/cef/wiki/AutomatedBuildSetup.md#markdown-header-linux-configuration . Modify GN_DEFINES to add "use_gtk3=true".

Okay, go it thanks that really helped.
