Re: [Simh] Booting the vax750 simulator.
Interesting, I'd never played with lk for Ultrix. It appears that it comes with VAX C, which is part of the base Ultrix packages. VAX Fortran was definitely a separate, paid addon. lk can indeed produce load maps, with lk -M. It also seems that at some point someone thought this would be a good idea to add to regular ld, but never really got very far - ld -M produces what the manual calls a primitive load map, which is really nothing more than a list of object files being linked. -Henry On 7 July 2015 at 14:57, Clem Cole cl...@ccc.com wrote: Mark, No problem -- Indeed, nm -n has been my friend for years. That said, I was replying to Henry's comment about the lack of a link map/output file for Ultrix. Indeed, my experience over the years is that there are times when a link map can be handy and I remember that Ultrix (as opposed to pure joy could create them). I faintly remember when the feature request came into Unix-land asking that the Unix ld be changed to add them and the reply was to use the VMS linker that had been modified to grok a.out (for Fortran - I had forgotten why it was done - Paul reminded me - at the time it was felt that it was easier to port the DEC linker than try to add the features Fortran needed to BSD's ld). I just had forgotten the details, but as I expected; he who authored the hack, did indeed remember them. The key is that if you have lk from the Fortran kit, it can be used to create a.out files. That said, I wonder if their are features supported by ld that lk did not (and might be used by the kernel linkage). I suspect lk ld but not a complete super-set. My experience with the language team is that they would have only done enough to make the DEC languages (and in particular) VAX Fortran work. I have faint memories of playing with lk (but had forgotten the command name and anything much else other than it existed). BTW: when he came over he tells me lk was further hacked to support Elf in later version, he started saying well if you used the itanium VMS port you can get a VMS to create linux binaries. - I said that was more than I though people cared about I think for this exercise.
