Re: Cross-building on Mac OS X with -isysroot

-isysroot=dir: Use dir as the logical root directory for headers. For example,
if the compiler would normally search for headers in /usr/include, it will
instead search dir/usr/include.
On Mac OS X this flag is used to point to a SDK directory with complete set of
compilers, headers and libraries, frameworks, etc., for example:
CPPFLAGS+= -isysroot /Developer/SDKs/MacOSX10.5.sdk
I use an environment where Xcode is installed without "UNIX Development" set of
tools and I need -isysroot to compile NetBSD and PkgSrc.
