            Bug ID: 178937
           Summary: [WPE] Add some error reporting during EGL
                    display/context creation
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit WPE
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aperez at igalia.com
                CC: bugs-noreply at webkitgtk.org

Currently it is very hard to determine what went wrong when EGL fails
to create valid contexts for us, with only the following being written
into standard error (see bug #178896 for one instance of this):

    PlatformDisplayWPE: could not create the EGL display.

It would be a good idea to add some calls to “eglGetError()” and write
some more information to standard error on failure. Admittedly, using
“eglGetError()” won't get us particularly chatty messages, but it would
be better than the current situation.
