r12998 gated the RPCGEN_* recipes in common/dataio/Makefile on
USE_RPCGEN=yes, so with no libtirpc they were never run. As well as the
*_xdr.c modules, rpcgen emits form_x.h, which compilers/4glc/rules
includes - nothing to do with XDR - so a fresh checkout failed with:
No rule to make target '../../common/dataio/form_x.h',
needed by 'rules/generated/y.tab.o'
An existing working copy still built, because form_x.h was already
present as an untracked build artifact.
- common/dataio/Makefile: the RPCGEN_* recipes are unconditional again;
only the libXDRPACKER_* targets stay gated on USE_RPCGEN.
- m4/aubit_tools.m4: rpcgen is therefore required for a source build
even with --with-rpc=none. Fail at configure time with a message
naming the package (Debian: rpcsvc-proto) rather than at the obscure
make error above. Only errors when form_x.h is not already present,
so a tarball shipping the generated files still configures.
- configure: regenerated.
Verified on a clean 'svn export' of the tree: ./configure && make now
completes ("Thank you for using Aubit 4gl compiler"), 57 plug-ins built,
no XDR plug-ins (correct without libtirpc), and the LVARCHAR round-trip
tests pass against a live Informix instance using only that build.
