Re: [Ltib] Disabling glib package test - Freescale M54418

[Stuart Hughes]

Hi Francios,

Without looking at the code you're looking at I can't say.  I'd suggest
looking at the source, identifying why gcc is complaining and then
seeing if there's an update to the package that fixes this.

One possibility is that you cannot simply comment out the cross-compile
test.  You may need to set the result that the test would have set, had
it been run.  Often the tests are probing the system to see what it can
use, maybe the error you have is as a consequence of not running that
configure test.

Regards, Stuart
