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

[Amit Mahajan]

Hi Amrit

I have not read the mails properly but i guess you are having problems while
building OKL4.

SOme days back i tried building OKL4 and linux over OKL4 on my hardy ubuntu
and ran it in qemu.

I have prepared a doc for the steps and requirements for the same, it may
helpful. Please check the doc attached.

Thanks and Regards
Amit Mahajan


First they will ignore you, then they will laugh at you, then they will
fight with  be helpful you, then you win.
