Re: [xml] Apple/Darwin Multiple Architecture OS-X

["Eric S. Eberhard" <flash vicspdi com>]

For those that care I did find a solution ...

I slightly modified the Makefile to allow an architecture to be 
set.  I then made a script to set the environment to "-arch i386" and 
compil and copy the .a to another name, then compil again using 
"-arch ppc" and copy the .a to another name, then use lipo and ranlib 
to put it all back together.  Works great -- script is:

rm 
.libs_i386/* 

rm 
.libs_ppc/* 

rm 
.libs/* 

(export ARCH=i386 ; make clean ; 
make)
mv .libs/* 
.libs_i386 

(export ARCH=ppc ; make clean ; 
make)
mv .libs/* 
.libs_ppc 

cp .libs_i386/libxml2.a 
.libs/i386.a
cp .libs_ppc/libxml2.a 
.libs/ppc.a
(cd .libs ; lipo i386.a ppc.a -create -output ese.a ; ranlib ese.a ; 
libtool ese.a -o libxml2.a)

and change to Makefile is one line -- add ARCH to CFLAGS for example:

CFLAGS = -arch $(ARCH) -O2 -Wall

It does seem to work on both platforms with my application just 
find.  I also had to add "-dead_strip" to LDFLAGS for example:

libxml2_la_LDFLAGS = -dead_strip -version-info 7:11:5

This flag keeps unused name references from causing trouble.

It would seem appropriate to have configure somehow handle this but I 
don't really know how to do this.  Any volunteers?
