[Axiom-developer] [MACOSX] What is unexec and why does it fail ?

[Pierre Doucy]

Hi all,

Attempting to compile Axiom on my Mac, I get the following error :

[...]
44 invoking make in
/Users/pdoucy/Documents/Travail/Axiom/axiom--MACOSX--1--patch-1/src/boot
with parms:
SYS= MACOSX
LSP= /Users/pdoucy/Documents/Travail/Axiom/axiom--MACOSX--1--patch-1/lsp

Error 1
make[2]: *** [bootdir] Error 2
make[1]: *** [srcdir] Error 2
make: *** [all] Error 2

As it looked like a memory problem, I changed my gcl configure options to:

./configure --enable-vssize=65536*4 --enable-maxpage=256*1024
--enable-machine=powerpc-macosx --enable-dlopen --disable-locbfd

but still get the same error.
After some googling, I haven't been able to find any clear doc about
what unexec is, and what it does.
Can anyone explain me what it is supposed to do, and why it might fail
in such a manner ?

Thank you in advance.
