Building InDesign CS4 plug-ins once for both MAC PPC and MAC Intel

Hi All,

I would like to know if there is a possibility to build the indesign plugins once for both PPC and Intel on MAC. Right now I'm forced to build my plugins twice: on the PPC machine and on the Intel Machine.

I tried to build the SDK example Basic Persist Interface on my MAC Intel machine and then i placed it on my MAC PPC and it failed to load.

is there any configuration I need to specify so the XCode linker will link for both machines?

I'm using:

InDesign CS4

Leopard 10.5.8

XCode 3.0

Architectures: i386

Valid Architectures: ppc67 ppc7400 ppc 970 i386 x86_64 ppc

Instruction  Sheduling Power pc G4

thanks,

Itamar
