embedded libraries for PDP-11, was Re: [HECnet] DECUS RSX C compiler

Will there be compiler compatibility issues there? (like with anything done in assembler, asm/C interface etc?) You could use the DECUS C libc, but you need to rewrite part of it. I bet the calling convention for gcc isn't the same as for DECUS C. Also, DECUS C does not expect to run on bare metal, so some basic I/O functionality needs to be written as well. But this is all pretty simple if you know your assembler.

Ultrix-11 tapes are available on Minnie

by gregg.drwho8＠gmail.com

Hello! Does anyone have any experience with the collection of tapes that contain Ultrix-11 there? I have them, and, ah, I'm still working out the details behind everything. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

DECnet on 4.3BSD/TOPS-20 and other questions

I need to get a newer shell to build pkg-config or pkgconf (pkg-config compatible thing, probably easier to use it) so I can get glib built. But I doubt pkg-config will ever build., so the plan stops there unfortunately It seems GNU configure scripts are..picky about shells. They hate pdksh, tcsh, proper ksh, and it seems pkgconf needs a modern bash. I've tried to build several shells as of yet no luck. Seems sys/time.h needs a bit of work for the history functions of bash3 to build. Maybe I can backport that from FreeBSD? Probably too many dependencies for that. I managed to get locale.h and sys/cdefs.h ported back to build with older GCC, i don't trust it but it built :-). But it would probably be a bit easier on a different 4.3BSD flavour.
