Hi, Peter

I just committed changes to gnu libtool to allow the -isysroot flag through
to gcc unmolested. However I did do some work on older libtool-1.5.x
...
CC="cc -arch ppc -arch i386 -isysroot=/path"
CXX="c++ -arch ppc -arch i386 -isysroot=/path"
CPP="cc -E"
CXXCPP="g++ -E"

Note that you need an automake newer than Apple ships. Latest is 1.9.6, I
think 1.8.2 or so started adding the --tag argument for glibtool.

imagine something like this

$SDK_DARWIN8
here libSystem.dylib with _newsymbol

$SDK_DARWIN7
here libSystem.dylib

if don't want that your configure script catchs _newsymbol
you have to make something like that

./configure CC="${CC} $SDK_DARWIN7/usr/lib/libSystem.dylib"

i've made my own tool
now i can compile against these targets from (Tiger-ppc)

gcc-3.5 ( without lmx )

-> /Developer/SDKs/Darwin7u.sdk  arch x86
-> /Developer/SDKs/Darwin7u.sdk  arch ppc
(including X11 FAT)

gcc-4

-> /Developer/SDKs/Darwin8u.sdk arch x86
-> /Developer/SDKs/Darwin8u.sdk arch ppc
(including X11 FAT)

gcc-4

-> /Developer/SDKs/Darwin8u.sdk arch x86
-> /Developer/SDKs/Darwin8u.sdk arch ppc

_m.o foo.c
imac:~/foo peter$ cc -fno-pic -c -o foo_nopic.o foo.c
...
ld: foo_nopic.o has local relocation entries in non-writable section

yes i've tested but it wasn't clear
i've misunderstood about PIC (position independent code)
in fact,  i made this (automatically without really understand)
it's for my culture :)

ok , so i can  sum like that

--NOT NEED PIC--

ar rc libMy.a *.non-pic.o

gcc -dynamiclib *.pic.o \
-install_name /usr/local/lib/ libMyOther.1.dylib \
-compatibility_version 1
-current_version 1.3
-o libMyOther.1.0.dylib \
-lz ./libMy.a

--NEED PIC--

ar rc libMy.a *.pic.o

gcc \
-dynamiclib \
-undefined suppress \
-flat_namespace \
-single_module \
-all_load ./libMy.a \
-install_name /usr/local/lib/libMy.1.dylib \
-compatibility_version 1
-current_version 1.3
-o libMy.1.0.dylib \
-lz
