Help: Large File Support (> 1GB) / Solaris 8 |

Hello Emacs Users - I have a need to read in large files and need
some advice. First, from the FAQ:
Old versions (i.e., anything before 19.29) of Emacs had problems
editing files larger than 8 megabytes. As of version 19.29, the
maximum buffer size is at least 2^27-1, or 134,217,727 bytes, or 132
MBytes. Emacs 20 can be compiled on some 64-bit systems in a way
that enlarges the buffer size up to 576,460,752,303,423,487 bytes,
or 549,755,813 GBytes.
It's the phrase "in a way" that has got me puzzled. My compile
platform is a Solaris 8 sparc box, with the Sun WSPro
compilers. I have followed the guidance in etc/MACHINES:
To build a 64-bit Emacs (with larger maximum buffer size and
including large file support) on a Solaris system which supports
64-bit executables, use the Sun compiler, configuring something like
this (see the cc documentation for information on 64-bit
compilation): env CC="cc -xarch=v9" ./configure
Yet I still cannot break a barrier of 256MB, even though I have
a very cleanly compiled version of emacs 21.2, that are 64bit
executables:
$ file emacs*
emacs: ELF 64-bit MSB executable SPARCV9 Version 1
emacs-21.2: ELF 64-bit MSB executable SPARCV9 Version 1
emacsclient: ELF 64-bit MSB executable SPARCV9 Version 1
549,755,813 GBytes? I'd be happy with 1 GB at this point. Any
help is appreciated. Thanks in advance,
Luke
