64 bit emacs 25.1 on AIX

64 bit emacs 25.1 on AIX

[Perry Smith]

Hi,

I’m trying to build emacs 25.1 using gcc 4.5.2 in 64 bit mode.  I have gotten to the point that temacs is created.  It does not dump (or unexec) but that is something I was hoping I could work on when I have time.

What I’d like to do for a temporary measure is just use temacs.  It does load up a bunch of stuff but I tend to just keep my emacs running so the time penalty isn’t really a big deal to me.

The first stumbling block was I needed to change PATH_DUMPLOADSEARCH.  I did that.

Now, I’ve discovered that loadup.el sets exec-path to nil.

Rather than track down and figure out all these things, I thought I would just ask: “what is the recommended way to use temacs rather than the preloaded emacs?"

Thank you,
Perry Smith

The temacs procedure has bitrotted a bit, I'm afraid. Ken Raeburn is 
working on this, as one idea for fixing the Emacs dump problem is to 
always run in temacs mode. See the scratch/raeburn-startup branch in the 
Emacs git repository. Although this is not ready for prime-time, it may 
be good enough for your purposes. The latest email I recall receiving 
from Ken on this subject is archived here:

AFAIR, temacs was ever only used for testing and debugging Emacs.
