Mali Graphics Debugger - GL Vendor,Renderer,Version all Unknown

Hi,

Sorry about the delay in response. Looking at the error you have presented: "DlOpenInterceptor: FATAL: Could not find libdl.so.2".

It looks like the interceptor can't find libdl.so.2 on your system. The interceptor uses this library to open the Mali Driver with a call to dlopen. If you run the command ldd libinterceptor.so it will list the libraries that are needed to use the application and I believe that it won't be able to show you the path to libdl.so.2.

There can be two reasons for this. The first (unlikely) is that there is no libdl.so on your system. The second is that your libdl library isn't called libdl.so.2. It maybe be called libdl.so or libdl.so.1. In the second case what you need to do is find the location and name of your libdl library. Then create a symbolic link between your libdl library and the one mgd is expecting.

ln -s locationOfYourRealLibdl.so libdl.so.2

Hope this helps,
Stephen

Hi,

I'm having same issues with Asus Tinkerboard that daemon cannot identify the Mali GPU:

ERROR: DeviceInfo: Unable to load GPU information (GL_VENDOR, GL_RENDERER, GL_VERSION) for this device.
ERROR: DeviceInfo: eglInitialize, EGL error: 0x3008

I've added export LD_LIBRARY_PATH=/usr/lib and libraries are symbolic links to libMali.so (because that's what rockchip provides). 

lrwxrwxrwx 1 root root 10 Jan 1 1970 libEGL.so -> libMali.so
lrwxrwxrwx 1 root root 10 Jan 1 1970 libEGL.so.1 -> libMali.so
lrwxrwxrwx 1 root root 16 Jan 1 1970 libFLAC.so.8 -> libFLAC.so.8.3.0
-rwxr-xr-x 1 root root 366880 Jan 1 1970 libFLAC.so.8.3.0
lrwxrwxrwx 1 root root 10 Jan 1 1970 libGLESv1_CM.so -> libMali.so
lrwxrwxrwx 1 root root 10 Jan 1 1970 libGLESv1_CM.so.1 -> libMali.so
lrwxrwxrwx 1 root root 10 Jan 1 1970 libGLESv2.so -> libMali.so
lrwxrwxrwx 1 root root 10 Jan 1 1970 libGLESv2.so.2 -> libMali.so
-rwxr-xr-x 1 root root 17602544 Jan 1 1970 libMali.so

All OpenGL ES 2.0 applications work corretly, but daemon don't recognice Mali GPU and connection from GUI fails.

Br,
