Build fails on network home directories mounted over AFP + Parallel make doesn't work

Build fails on network home directories mounted over AFP + Parallel make doesn't work

[Alastair Houghton]

Hi there,

Just a note to let you know that Emacs currently (latest sources from  
CVS) won't build on Mac OS X if the sources are in a folder mounted  
remotely via AFP.  The problem seems to be related to an attempt to  
create a hard link (from "emacs" to "emacs-<version>") during the  
build process.

Additionally, GNU Make's parallel make feature prevents Emacs from  
building successfully (typically this results in "require" failures  
when loading Elisp files).

Both are easily worked around; builds on local disks on OS X work  
fine, and using non-parallel make also works.

Kind regards,

Alastair.

Thanks, but please show the transcript of a build session where the
problems due to parallelism are clearly visible.  We need to fix this
problem.

I can't reproduce it after doing a new cvs update, so it looks like  
whatever was going wrong has already been fixed.  It was reliably  
reproducible before the update using -j2 on a dual-processor PowerPC  
Mac.

I'll remember in future to include a build transcript if I have to  
report this kind of bug again.

Kind regards,

Alastair.

I couldn't reproduce that with -j16 when building for ia64-linux, using
the current CVS sources.

And I can build on MS-Windows using -j and -jN with N from 2 to 10.
That's why I asked for a transcript.
