VM build error of the week:

Alan Grimes
This is with the current SVN sources and a freshly generated interpreter
from a clean, fully updated, 3.8 image.

I have not been able to build a VM in 6 months or so...
What happened to the good old days when the VM would always build and
the only errors were a result of my own ill-advised hacks?

FFI needs to work in order to support Croquet... =\

Re: VM build error of the week:

johnmci
Actually if you generate a new VM using the latest VMMaker, ask Tim,  
you will find it will generate
a backwards compatible entry point so that older versions of the FFI  
plugin will still work

However I'm not sure you've generated a new vm and ffi plugin because  
of the warning messages
you have received below

  #warning * interp.h not found -- defaulting to a 32-bit VM
The unix vm config process builds this file.


#warning * update your image-side VM sources to the latest
#warning * version to avoid this message

VM documentation.

Alan Grimes
In reply to this post by Alan Grimes
Last time I complained about the lack of VM API documentation someone
mentioned an obscure out-of print book that documents an obsolete
version of the interface...

Well, I need it.

Mr. Boyce has offered me a sweet comission to port the thing to an OS
that Doesn't Completely Suck(tm)

This means I need the inf0z...

=\

I'm looking at Duncasse's archive but I'm not sure which title I'm
looking for...

It's neither out of print nor obsolete:

Comment:

Gcc 3.1.0 had problems with its optimizer such that it inserted
worthless register loads into the instruction stream -- maybe that bug
is back.....

With gcc 3.1, the performance saw a substantial improvment when it was
compiled with -O0 -- that was not the case this time...

With -O1, however, there was a substantial improvment, though still much
worse than my workhorse VM...

Re: Benchmarks of Ian's 3.7 beta with gcc 3.4.4

Andreas.Raab
And the lesson is: Stick with the compiler that produces the best code,
not the highest version number. I'm still using 2.95.2 on Windows and as
long as there isn't a GCC version which is at least at par with 2.95 on
x86 (all other versions I've tried where substantially slower) I won't
switch ;-)

Cheers,
