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

Hi Stuart,

Quite a few actually by calling $ ./ltib, but it is failing at glib, in pkg-config.

ok so I reverted to the version in LTIB, which is 0.21.  I can see a glib copy with it, version 1.2.8.

Yes. There is some FIXME labels in it, and there is the variable 'cross_compiling' in there that I have assigned to 'no'.  That made it work, the error is gone.  Now there is a different one in the same module, but it is progressing:)

checking size of char... configure: error: cannot compute sizeof (char), 77
See `config.log' for more details.

Got to continue fixing the configure script I guess. Thanks.

Thank you,

Hi Francois,

I didn't really follow that completely what you are saying.

The pkg-config in LTIB is setup to work with cross compile.  It's a
"special" patched version in /opt/ltib/usr/bin/pkg-config that is able
to use a relative path to figure out include/libs.

Am I right in thinking the problem you have is you're trying to build a
package and are getting this error:

>> checking for growing stack pointer... configure: error: in
>> `/ltib/ltib-modelo-20100709/rpm/BUILD/pkg-config-0.28/glib':
>> *configure: error: cannot run test program while cross compiling*
>> See `config.log' for more details

If so, then I don't think pkg-config (being called from configure) is
the problem.  As I tried to say before you need to fix the configure
script in the package you are adding so that it does not have to run the
cross compiled test.

What package are you trying to build?

Regards, Stuart
