[comp.unix.ultrix] Problems with gcc-1.37.1 on VAX/Ultrix3.1

jpe@egr.duke.edu (John P. Eisenmenger) (07/03/90)

I am having trouble building a working version of gcc 1.37.1 on a VAX
running Ultrix 3.1.  I built gcc as if I were on a BSD VAX.  I changed
only the CPP_PREDEFINES to define "ultrix" and "bsd4_2" like Ultrix's
cpp.  The build was successful through the stage2 test and everything
looked great.

The problem is that sometimes gcc will generate code that dies with
an "illegal instruction" message (Most notably in some X11R4 clients
and the g++ library test).  I haven't begun looking into it yet, as
I'm hoping for a quick response from someone else's trials.

Are there other changes that need to be made for building on a VAX
running Ultrix?

Thanks in advance for all responses.
