There is no GLES2 support in Gnash beyond a few minor bits of code. It was a GSoC project that had limited progress. The GLES1 support is also incomplete. It is based on an ancient patch to Gnash 0.8.5, all I did was fix the old patch so it would compile. Patches to get the GLES1 code working would be appreciated.

And another thing. I realized EGL is not found.
HAVE_EGL_EGL_H is not set. This triggers a #error in libdevice/egl/eglDevice.h

false positive on gles1. There is a libGLESv1_CM.so.

macros/gles.m4 has a few faults.
Again, I am using teh raspberry pi and specifying the path to gles2 lib by --with-gles2-includes=/opt/vc/include --with-gles2-lib=/opt/vc/lib
In its current state, GLES2_LIB is empty while the gles2 headers were found and include paths properly set inside GLES2_CFLAGS in all Makefiles generated by configure. I have seen a few logical issues in the macros/gles.m4

lines 199,200
the for-loop uses j, but the check for existing files uses $i.
Aditionally the code in line 200 checks for files named like GLESv2.a(wrong for me) instead of libGLESv2.a(right for me).
Same things lines 210,211.

When these 2 thigns are fixed, the code will act weird. there is a list of libraries given as gleslist1 or gleslist2.
line 190: gleslist2="EGL GLESv2"
As far as I am concerned, both libEGL and libGLESv2 are needed. Now the code in lines 210-215 will find libEGL and then finish. In the Makefiles GLES2_LIB will only contain -lEGL. So -lGLESv2 is missing.

Besides, I dont know what gles1 is used for but the raspberry pi is supposed to support gles1 too. There are include files for it, no GLES/egl.h though. and there is no libGLESv1.so. Instead, libGLESv2.so contains also gles1.
