On the error lines, you can try replacing "unsigned" with "const char *". That should at least fix those errors. If that for some reason doesn't work, you can replace it with "unsigned long long", but that will make l4linux no longer compile for x86_32.

i tried to run l4linux over foc_x86_32 platefrom it ran well. now after building the build directory for foc_x86_64 i am agian trying to run the run script of l4linux from the build directory then i am getting this error 

I have changed the <spec>.conf and of the ports-foc and other  tarhget.mk for my

foc_x86_64 but it is not working the error is :

the same thing works fine for foc_x86_32
