Problems during setup Mali Graphics Debugger on Android 4.1

guozhu

System Info

graphics: Mali-400MP, android version: 4.1.1, Mali Graphics Debugger: 2.0

when I try to setup the Mali Graphics Debugger  on android device following the user guide.

the libGLES_mgd say it can't load the libGLES_mali.so (because this library isn't here, but libEGL_mali.so and the other two).

files in /system/lib/egl/ :

shell@android:/system/lib/egl # ls

egl.cfg

libEGL_mali.so

libGLES_android.so

libGLES_mgd.so

libGLESv1_CM_mali.so

libGLESv2_mali.so

but the mgd only try to load libGLES_mali.so (/vendor/lib/egl/ have been mapped to /system/lib/egl/):

I/libGLES_mgd(30489): libGLES_mgd is in a system folder

E/libGLES_mgd(30489): Failed to parse process mappings.

D/libEGL  (30489): loaded /vendor/lib/egl/libGLES_mgd.so

any suggestion is appreciated

    You will have a real GLES library somewhere on your device - this is normally called libGLES_mali.so, but it is possible for a system integrator to rename it to something libGLES_<foo>.so. I think you need to set up a symlink at /vendor/lib/egl/libGLES_mali.so which points to the real library.

    > libEGL_mali.so and the other two


    One possibility is that the device driver for your platform has not been built as a single library, but has three separate libraries - if this is the case I would suggest asking your platform provided for a monolithic driver build (added advantage is that it is normally faster too).

    HTH,
