[Q] Is the 10.4u SDK distributed for the Intel Mac and the PPC Mac different?



Hello.

I tried compiling the postgreSQL library. As I desribed in my previous post, on Intel Mac, there are some problems like "_fnctl $UNIX2003 can't be found.". I tried investigating the library file using the nm. But they are reference like _fnctl without $UNIX2003.

So, I tried compiling universal library, especially the i386 part, on my iMac 17" PPC (Sunflower model.)
I found some interesting things.
An intel binary built on an Intel Mac is 420KB, while the same intel binary built on a PPC Mac is 392KB.


The build command is the same on both.

export CFLAGS="-O -g -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -mmacosx-version-min=10.4"
export LDFLAGS="-arch i386"
sudo ./configure --prefix=/opt/local --disable-dependency-tracking.


I couldn't provide it with -arch ppc -arch i386 at the same time. Then erros will be thrown while compilation.
So, I tried buiding the separately and will combine them using lipo.


Is there any difference between the same 10.4u SDK? (Actually I think I heard it before from somewhere... )

Thank you.
