Hi > We are trying to port a newly developed device driver for powerPC . > We are unable to compile it for powerpc driver on Host platform. > Please give us the way to compile the device driver You need to cross compile, which means having a ggc for powerpc in addition to the gcc you have for your developpement machine. I do not know whether you will find it on the net, usualy you have to recompile gcc (and "ld" and "ar" and so on, the whole gcc toolchain I think) with specific options
Then you will have a powerpc-linux-gcc (for example) which will be able to compile for powerpc then, you will have some modifications to do in the makefiles: look for this string: "CROSS_COMPILE" and set it to "powerpc-linux-" (or whatever is the prefix for you gcc). I also created a ".arch" file at the base of the source tree, containing "ppc" and some other modifications in makefiles, but I cannot tell you wich... and wether they are usefull. You'll have to try. Then add "ARCH=ppc" option to the make command when you want to compile your kernel for powerpc. Have fun. +++ ---- Nathael PAJANI Ing?nieur CPE Lyon nathael.pajani at cpe.fr
