Building on Mac (Intel) [patch]

[David Reitter]

Building on Intel Macs works fine except for two issues.

The first one is minor and solved by the patch below. Building fails  
with --self-contained otherwise for obvious reasons.

The second issue I'm having is more problematic:
Building fails regularly due to what seems to be a problem with my  
site-load.el and dumping in the bootstrap phase. I usually get   
(during temacs -batch -l loadup bootstrap):

Writing LC_TWOLEVEL_HINTS command
Writing LC_UNIXTHREAD     command
unexec: not enough room for load commands for new __DATA segments
make[2]: *** [bootstrap-emacs] Error 1
make[1]: *** [bootstrap-build] Error 2

or, depending on how much is in site-load, this:

Writing segment __DATA           at 0xa6e000 - 0x1276000 (sz: 0x808000)
Writing segment __IMPORT         at 0x1276000 - 0x1279000 (sz:    
0xunexec: not enough room for load commands for new __DATA segments
3000)
Writing segment __LINKEDIT       at 0x1279000 - 0x1578438 (sz: 0x2ff438)

My SITELOAD_PURESIZE_EXTRA is set to 2000000. Increasing or  
decreasing the value doesn't help.

I can reproduce the problem with a minimal site-load.el as follows:

(load "emacs-lisp/debug")
(load "emacs-lisp/byte-opt")

... and calling "temacs ... bootstrap" directly.

Without either of the above site-load.el, things seem to work  
smoothly with about the following result:

56 unused bytes follow Mach-O header
75052 pure bytes used

So it looks to me like there is not enough pure space allocated  
during the bootstrap phase and SITELOAD_PURESIZE_EXTRA is ignored.  
Maybe PURESIZE_RATIO plays a role.

I have been using the full site-load.el without problems for hundreds  
of compiles with PPC OS X.

Any suggestions as to what to check next?
