However, for question 2, I'm not yet sure.
The only requirement wrt rpcgen, is that it must be the Linux GLibC rpcgen binary. This is because our post-processing script to fix various compiler warnings only works with the code generated from that. Hence we do not want a configure time use of rpcgen, and should include the generated files in 'make dist'. Since our release tar.gz archives are always generated on a RHEL box, we don't need them in GIT. > >> The remote_generate_stubs.pl generated headers with prototypes and > >> dispatch tables for the RPC exposed functions: > >> daemon/(remote|qemu)_dispatch_(args|table|prototypes|ret).h > > Here, there's only one question: > 1. do we want a configure-time dependency on perl?
