This is normal for objects that don't have any code or data because the sources were reduced to nothing by `#ifdef DEBUG' or similar. cc generates objects that are empty except for a couple the labels `___gnu_compiled_c' and `gcc2_compiled.' and `make' runs `ld -r -x' to remove usless and useful labels (silently so that you can't see what it is doing). >/usr/lib/librpcsvc.a >nm: yppasswd_xdr.o: no name list. >nm: spray_xdr.o: no name list. >nm: sm_inter_xdr.o: no name list. >nm: rwall_xdr.o: no name list. >nm: rstat_xdr.o: no name list. >nm: rquota_xdr.o: no name list. >nm: rnusers_xdr.o: no name list. >nm: rex_xdr.o: no name list. >nm: nlm_prot_xdr.o: no name list. >nm: nfs_prot_xdr.o: no name list. >nm: mount_xdr.o: no name list. >nm: klm_prot_xdr.o: no name list. However, most of these shouldn't be null. Check the machine-generated sources for them. Here only rwall_xdr.o and rwall_xdr.c are null. Bruce
