I find this a little worrying. The previous two versions of nhc were quite painless to build on all sorts of systems, including Solaris and OpenBSD: this is not an advantage that should be given up easily!

I am sorry that you are having these problems, but it is inevitable that different operating systems have slightly different properties, and we cannot possibly test on all of them. Nevertheless, we do aim for nhc98 to be as painless as possible to build on any Unix-like machine. Your bug reports are very valuable in helping us to achieve that aim.

It looks like your machine's version of 'ar' might differ from GNU ar. Those symbols are defined in the source file src/hat/tools/FunTable.c, which is compiled by $(CC) and added to the hatlib.a archive by the command ar -rc $(OBJDIR)/hatlib.a $(THOROBJS) The error messages refer to `observe.c', which is also a member of the archive. Perhaps you can use nm .../targets/ix86-OpenBSD/obj/hattools/hatlib.a to determine whether the file Funtable.o exists in the archive, and whether it does indeed define the symbols which are claimed to be missing. Send me any interesting information you find. Regards, Malcolm
