Universal binary packages on Mac OS X

[Adam Ciarciński <adam%NetBSD.org@localhost>]

Hi,

I have succeeded building universal binary (fat) packages from pkgsrc  
on Mac OS X, and I would like to share some thoughts on this matter:


*** Bootstrapping fails on libfetch. I had to change bsd.lib.mk to:
.c.o:
        ${COMPILE.c} ${.IMPSRC}
otherwise, with the default "${LD} -r", fat library is stripped down  
to one architecture. I wonder why don't we leave this target that way?  
For other systems, too.


*** digest-20080510 builds as universal binary, but doesn't work  
correctly for SHA1 algorithm, since it sees my PowerPC as little- 
endian architecture. I guess the endianess is taken from 'configure',  
and should be derived from #includes. (For other packages, I noticed  
the 'configure' script discovers endianess as 'universal'.)


*** "-MT filename.o" option has to be discarded from gcc. I noticed,  
in couple of packages, the -MT filename is the same as the target (- 
o), so it doesn't change anything. Or does it? I have changed mk/ 
wrapper/arg-pp-darwin-gcc to consume the option, but maybe there is a  
better way to do it.


*** some packages, like graphics/jpeg, have minor problems, but can be  
easily fixed. Others, like devel/SDL, can't detect/use AltiVec, but  
build and work anyway.


Kind regards,
Adam
