How to port CDC for PowerPC

Question

hi,
     I have downloaded the j2me_cdcfp-1_0_1-fcs-doc-b12-linux-i686-14_May_2002.zip and
j2me_cdcfp-1_0_1-fcs-src-b12-linux-i686-14_May_2002.zip
I was able to build the cvm for Linux-i686, since there is no other source for CDC for Powerpc.
I tried top Cross compile it for Powerpc using the exsting *.mk file in linux-powerpc.
I have changed the GNUmakefile to support the powerpc with arch=powerpc. it poped the following Error
issued the following command in ./build/linux-powerpc
------------------------ ERROR --------------------------

i understand that the assembler say that your trying to complie the powerpc on i686 machine.
how can i cross compile it for Powerpc using linux-i686 machine, and use for embedded application
thanks in advance

Hello Syed MA,
if you are looking for a CDC compliant Java Virtual Machine, IBM have written one that works on Linux on PowerPC (and on other processors too).
Have a look at http://www-3.ibm.com/software/wireless/wme/
It supports CDC and the Foundation Profile. I beleive that buying this rather than building your own is probably better in the long run as the IBM one has been certified as CDC compliant (passed the TCK tests).
Running your own Technology Compatability Kit tests (TCK) is very expensive.
I think the IBM virtual machine costs about €6.00 per unit to deploy but is free for developers.
Give me a shout if you need any more advice.
Matt :)
