What happens if you comment those lines out (and >> then re-run autogen.sh)? Note that Makefile.am for rpcgen and >> rpcdebug also have these lines, but they may not need to be built when >> cross-compiling? When all is said and done, rpcgen needs to run on the build host, not on the target. I thought this was here for building on platforms that don't have rpcgen installed... (I think we should consider removing rpcgen from nfs-utils, in favor of requiring the officially installed rpcgen to be available). Does nfs-utils actually install rpcgen on the target? If it does, then ignore me. >> >> K.C. > Hi Kevin, > > You're absolutely right.
