[xml] Apple/Darwin Multiple Architecture OS-X

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

I am using a very old libxml2:  2.5.11 mostly because it has worked 
well for me for a long time.  I have it working on Windows, Linux, 
AIX.  I am having a very hard time with the Apple.

My application -- which links to libxml2.a on the other platforms -- 
is compiled for both Apple architectures (i386 and ppc) and loaded in 
to "fat" libraries (meaning both architectures are loaded into the 
single library).

libxml2 installed and configured just fine on the apple and make a 
.dylib and a .a that by all appearances are OK.

Apparently linking fat files with thin files does not work at 
all.  And the libxml2 files are indeed thin files with the ppc 
architecture (this is a ppc machine).

So I did the obvious ... I modified the Makefile with "-arch i386 
-arch ppc" in LDFLAGS.

And I get the following error when trying to link:

gcc: -E, -S, -save-temps and -M options are not allowed with multiple 
-arch flags

This would seem simple enough ... remove those flags.  Yet they are 
not in my compil/link!  See the actual gcc line it is using:

gcc -DHAVE_CONFIG_H -I. -I. -I. -I./include -I./include -D_REENTRANT 
-g -O2 -Wall -arch i386 -arch ppc -c SAX.c -MT SAX.lo -MD -MP -MF 
.deps/SAX.TPlo  -fno-common -DPIC -o .libs/SAX.lo

I am hoping there is a configure option I can use ... but I am not 
finding it.  Or some other way to build libxml2.a or equivalent (I 
prefer static library with dead-strip and both architectures).

Does anyone know how I can do this :-) ?

Thanks!
