-----------------------+----------------------------------------------------
ECL 11.1.1.p0 spkg does not build on MacOSX PPC (G4) running MacOSX 10.5,
and using XCode 3.1.4 (the lastest XCode for this platform).
Symptoms: a crash half-way the build, at the log point
{{{
;;; About to load cmp/load.lsp
;;;
;;; Now we are in shape to do something useful.
;;; End of bare.lsp
}}}
it can be:
{{{
Internal or unrecoverable error in:
not a lisp data object
[2: No such file or directory]
}}}
or
{{{
Detected access to an invalid or protected memory address.
Available restarts:
1. (CONTINUE) Ignore signal
}}}
or
{{{
64 is an illegal index to "Variable in COMMON-LISP package:
The last-but-one top-level forme".
No restarts available.
}}}
or perhaps something else like this. This is apparently due to an ECL bug
having to do with altivec instructions.
Configuring with
{{{
./configure CFLAGS="-mno-altivec -mabi=no-altivec"
}}}
makes the ECL build OK. See
