[okl4-developer] Help regarding the OKL4 port to the Qemu Emulator

[Nicholas FitzRoy-Dale]

Hi Amrit,

Thanks for confirming that your build problem occurs for Versatile  
too. To definitely confirm that the problem is toolchain-related,  
could you please download the official OKL4 3.0 source from the OKL  
wiki and verify that you get the same problem building for Versatile?  
(I am assuming that you tested the Versatile build from the htcdream  
fork).

Doing this will confirm that there is a toolchain problem (if you get  
the same error) or allow me to narrow down the bug (if you don't get  
the same error).
