bbclass providing some level of scratchbox compatibility

bbclass providing some level of scratchbox compatibility

[Robert Schuster]

[-- Attachment #1.1: Type: text/plain, Size: 1235 bytes --]

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

Looks nice, but shouldn't we put the generated binaries (e.g. packages,
tarballs) in a special dir in deploy so there's no risk of confusing the
m with non-rpathed ones?
