It seems that while /usr/include/unistd.h has getattrlist, but it

SB2 is not fully supported on OS X. It was possible to compile sb2 for
it, but sb2 haven't been used on OS X, AFAIK.
The technical reason why the OS X port was never finished is quite
simple: Even if OS X is "mostly mechanically compatible" with sb2's
requirements (i.e. OS X has the DYLD_INSERT_LIBRARIES feature, which
should be practically the same as LD_PRELOAD, etc), sb2 isn't all you
need: Both SB2 and Qemu are needed for embedded linux develompent. And
since sb2 uses the user-mode version of Qemu, that one should be able
to run elsewhere that just on Linux. It couldn't be used like that.
The things that were missing from Qemu were related to Qemu's system
call and thread support. Qemu _converts_ system calls from one HW
architecture to another, but didn't _translate_ syscalls between
different OS flavors. So, it really depended on being executed on Linux.
This was the situation at least ca. 2 years ago; someone from the Qemu
team might know if there has been any changes since that.
I put band-aid by rename of getattrlist in scratchbox2 as
sb_getattrlist, but after that I got another duplicate definition
error on glob as well.
All wrapped functions are defined in one interface specification file,
preload/interface.master. You'll need to change the prototypes for OS
X there.
And please use the latest sources from http://maemo.gitorious.org/scratchbox2/
, the old repository at freedesktop.org is not up-to-date, and won't
be updated anymore.
