Re: [Ltib] Sourcery G++ Lite 2010.09-55 for Power GNU/Linux toolchain

[Stuart Hughes]

Hi Aaron,

It's a while since I looked at this, but the -B switch, does pretty much
the same thing are your direct version.  The odd looking trailing // is
necessary as otherwise (much) older toolchains will fail (it's a bug in
the toolchains).

Once possibility is that for some reason the environment variable:
DEV_IMAGE does not get set properly, which would explain accessing
/usr/lib.  Alternately maybe the the path is not found using -B.

Unfortunately I don't have time to look into this at the moment.  Could
you try the following:

Put the code back as it was, but add:
        print "rootfs stating area: $ENV{DEV_IMAGE}\n";
near the top of the spoof_wrapper file.

If that looks okay, can you try building the helloworld test rpm with -v
added to the compiler line, along the lines of:

./ltib -p helloworld -m prep

Edit rpm/BUILD/helloworld-1.1/Makefile and change the line:

CFLAGS   = -Wall
to:
CFLAGS   = -Wall -v

and then run:
./ltib -p helloworld 2>&1 | tee helloworld_log.txt

If you look at the file you may be able to see whether the right paths
are being found for the linking.

Regards, Stuart
