Hi,  
  
  
  
I am getting the following error when trying to run SDK 3.0 R2 (for Linux) binaries on my Intel machine running Ubuntu 12.04 and has Nvidia video card.  
  
  
  
/opt/Imagination/PowerVR/GraphicsSDK/SDK\_3.0/Binaries/Linux\_x86\_32/X11/Examples/Beginner/01\_HelloAPI/OGLES2HelloAPI  
  
eglBindAPI failed (-1076696740).  
  
  
  
glxinfo |grep render  
  
direct rendering: Yes  
  
OpenGL renderer string: Quadro 600/PCIe/SSE2  
  
GL\_NV\_conditional\_render, GL\_NV\_copy\_depth\_to\_color, GL\_NV\_copy\_image,  
  
GL\_NV\_parameter\_buffer\_object2, GL\_NV\_path\_rendering,  
  
GL\_NVX\_conditional\_render, GL\_NVX\_gpu\_memory\_info, GL\_OES\_depth24,  
  
GL\_OES\_fbo\_render\_mipmap, GL\_OES\_get\_program\_binary, GL\_OES\_mapbuffer,  
  
  
  
This is after I have set:  
  
setenv LD\_LIBRARY\_PATH /opt/Imagination/PowerVR/GraphicsSDK/SDK\_3.0/Builds/OGLES2/Linux\_x86\_32/Lib/  
  
ls $LD\_LIBRARY\_PATH  
  
libEGL.so libGLESv2.so  
  
  
  
Can you please recommend what can I do (besides building them) in order to run them?  
  
Thanks!

Hi Rasko  
  
  
  
The libraries in the /Builds/ directory are stub libraries for used for linking. The actual libraries you should be pointing towards are located in /GraphicsSDK/PVRVFrame/EmulationLibs/, so you need to set LD\_LIBRARY\_PATH to something like /opt/Imagination/PowerVR/GraphicsSDK/PVRVFrame/EmulationLibs/Linux\_x86\_32

Thank you, Chris for the quick response.  
  
  
  
ls /opt/Imagination/PowerVR/GraphicsSDK/PVRVFrame/EmulationLibs/Linux\_x86\_32/  
  
libEGL.so libGLES\_CM.so libGLESv2.so  
  
  
  
Is there any additional installation user guide for this?  
  
I haven’t managed to find it in the user guide:  
  
ls /opt/Imagination/PowerVR/GraphicsSDK/SDK\_3.0/Documentation/SDKUserGuideContent/  
  
SDKUserGuideOGLES2LinuxARMv7 SDKUserGuideOGLESLinuxARMv7  
  
SDKUserGuideOGLES2LinuxX86PCEmulation SDKUserGuideOGLESLinuxX86PCEmulation  
  
  
  
Any way, all demos are working now. Thank you!

There is a short installation guide for the emulation libraries in the document located in:  
  
/GraphicsSDK/PVRVFrame/Documentation/.  
  
  
  
The confusion with the stub libraries isn’t currently addressed so I’ve asked our documentation team to take a look and make some amendments. Thanks for your help!
