compile freebsd on ubuntu

[王伟]

Dear friend:

    I  am compiling the freebsd kernal on ubuntu with this command :

    sudo bmake -j1 buildworld KERNCONF=MODEDKERNEL COMPILER_TYPE=gcc TARGET=amd64 TARGET_ARCH=amd64

    beacuse make cannot work so i use the bmake but it take the error that:

        rpcgen: execvp cpp: No such file or directory *** [key_prot.h] Error code 1

    how can i fix this error

    i download the system code from the github, and compile it on the workpalce.

    the full log is that:
