Fwd: [distcc] how to get separate compile tasks

[Yanchun Wang]

Thank you for your answer. Then if i send a same command, for example "make
–j4 CC=distcc –f makefile.x86_linux",
to all servers over the LAN, (and the program source files to be compiled
are stored on a shared disk. )
Servers call these commands. Then distributed multithreading compiling can
be realized. Correct?
