bbclass providing some level of scratchbox compatibility

Hi,
I am using OE to build binaries that can be run from within Maemo
scratchbox.

The binaries I create are for the native architecture (the one of the
host CPU) not the emulated one. Such binaries need a special rpath. What
the bbclass does is simply putting that special rpath in LD_RUN_PATH
before configuring and compiling. This has the effect that all built
binaries have it in.

Together with a halfway compatible toolchain (CS gcc3.4.4, glibc2.3.x)
that allows me to run those binaries in Maemo's scratchbox.

I am using this for Jalimo[0] and would like to push it upstream. I am
open for suggestions.

File a bug?

Regards
Robert

# By adding this class to your build all binaries get the special rpath
# "/scratchbox/host_shared/lib/:/scratchbox/tools/lib/"
# Doing so makes libraries and programs runnable inside the Scratchbox
# environment as native binaries (not for the CPU that Scratchbox is
# emulating).

do_configure_prepend () {
  export LD_RUN_PATH="/scratchbox/host_shared/lib:/scratchbox/tools/lib"
}

do_compile_prepend () {
  export LD_RUN_PATH="/scratchbox/host_shared/lib:/scratchbox/tools/lib"
}
