[Ltib] Re: add -DZ_PREFIX

[Stuart Hughes]

Hi Henry,

I'm busy with other work today, but I wanted to let you know that the
changes to make pkg-config work properly didn't go into LTIB until
mid-May.  To save yourself a lot of wasted effort, it's worth using the
later one you have.  If you need the older kernel, you can either build
it in the other instance and save it to /tftpboot/... or you can
re-active the older spec file (I think it's still there), this involves
updating config/platform/imx31/main.lkc and adding it into the kernel
choice list etc (it's in the FAQ I think). Is there any reason for not
using the later BSP/kernel?

The includes stuff will be fixed by pkg-config.  pkg-config is a host
support package and so should be installed by ltib
in /opt/freescale/ltib/usr/bin/pkg-config when you installed the later
BSP.  If it's not there, rm .host_wait_warning* in the later BSP and
then re-run ./ltib.

I will answer your other emails when I can get back to them.

Regards, Stuart
