I'm using msvc 11.0 and when trying to compile and run ex_shader.cpp I get:

Could not create display.
Assertion failed: display, file allegro-git\src\shader.c

I've tested a couple of other examples and they worked fine.

I was able to create the display by commenting out ALLEGRO_PROGRAMMABLE_PIPELINE but then it couldn't create the shader. I assume it's because I commented out that flag.

Edit: I have no idea how that "en" got there in the title.

Well, I'm using the binaries from the 5.1.6 release thread, I've tried to compile it myself before but I haven't had any success. I've had problems with both CMake and getting the dependencies to compile

Oh, I thought he meant when compiling allegro(which I haven't been able to do), and not the ex_shader.cpp. I've uploaded the allegro.log for ex_shader.cpp

Edit: Oops, uploaded the log for ex_shader_multitex.c I've uploaded the log for ex_shader as allegro2.log

I'm gonna take a wild guess and say that this:

shader.c:465  _al_create_default_shader        [   0.11030] No suitable shader platform found for creating the default shader.

might be the problem?

Alright, thanks
