[R-SIG-Mac] Build package failed on MacOS Leopard

[Fán Lóng]

Hi there,

When I build my R package with below command on leopard, MacOS 10.5,
it reports that the ppc architecture library file is missing. I was
wondering how can I build this package only with i386 arch, and don't
build the ppc architecture.

Below is my build command and build result:

----------------
R CMD build –binary my_package_src_dir
R_ARCH=/i386 R CMD INSTALL --with-package-versions my_package_tarball
