Issue with running Cobalt built with linux-x64x11 config

I'm trying to run current Cobalt trunk (12.81256) on Ubuntu 16.04. but it fails:

[0814/100203:FATAL:graphics_system.cc(130)] Check failed: 1 == num_configs (1 vs. 0)

I found that issue with EGL configuration comes from using:

EGL_BIND_TO_TEXTURE_RGBA, EGL_TRUE

Without it eglChooseConfig will return 1 configuration.

But then it will fail again, after call to

eglCreateWindowSurface()

in cobalt/renderer/backend/egl/display.cc

[0814/111151:FATAL:display.cc(53)] Check failed: 0x3000 == eglGetError() (12288 vs. 12297)

Since this is EGL_BAD_MATCH error, chosen EGL config is not good, but neither was the original one.

I tried with setting

'gl_type%': 'system_gles2',

in starboard/linux/shared/gyp_configuration.gypi, but results were the same.

Am I missing something?

Steps for reproduction of crash:

Build:

cobalt/build/gyp_cobalt -C debug linux-x64x11
ninja -C out/linux-x64x11_debug cobalt

Run:

./out/linux-x64x11_debug/cobalt

Is there maybe some dependency on EGL or GLES libraries?

Solution

Issue is related to which libEGL and libGLES libraries are used.

Following libraries were used on my system:

libEGL.so.1 => /usr/lib/nvidia-375/libEGL.so.1 (0x00007f66bbebc000)
libGLESv2.so.2 => /usr/lib/nvidia-375/libGLESv2.so.2 (0x00007f66bbcad000)

When using libraries from mesa:

LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/mesa-egl ./cobalt

Cobalt will start and work.

Thanks Daniel and Andrew for help.
