Hello,   
I am new to graphics development. I have a board with mpc5121e processor(with mbx core). I want to compile demos in the sdk for my card(embedded linux). I followed the instructions for linux. I copied the necessary so files into OGLESlinuxPPCLib ; and run " make PLATFORM=LinuxPPC". It compiles most of the object files but at some point it gives the following errors:

I think it cannot find the X11 libraries although i defined X11ROOT = /usr/include/X11 in the .mak file. Actually , the question is that why does it ask for X11 libraries? There is no X11 in my embedded board. What should i do to fix that problem?  
  
Thanks in advance…

Hi,

&nbsp;
  

Firstly, sorry it has taken so long to respond. 
  

&nbsp;
  

I know when we&nbsp;provided the SDK to freescale the platform for the SDK&nbsp;was&nbsp;defined to be 'LinuxMPC512' (not LinuxPPC) so it is possible you're using the wrong platform but it is also possible that&nbsp;it has been changed by freescale.
  

&nbsp;
  

Assuming the platform is correct as far as I can tell it should only build for X11 if X11BUILD is defined. Is it possible this has been defined?
  

&nbsp;
  

Thanks,
