Configure error

Configure error

[Gary Thomas]

A package I imported from OE (long ago) no longer builds
with this error:
| ERROR: This autoconf log indicates errors, it looked at host includes.

It's not obvious to me what the problem is nor how to fix it.
Can someone help with this, please?

See the logs at
    http://www.mlbassoc.com/poky/ConfigureFailure/config.log
    http://www.mlbassoc.com/poky/ConfigureFailure/log.do_configure

Thanks

The check looks at the config.log.  It is looking for instances where unsafe
compilation or include usage occurs.  In this case it wasn't actually host
includes.. so there is a bug in the error message.  From the config.log:

In the above snippet you'll see 'warning: library search path "/lib" is unsafe
for cross-compilation'.  This indicates that the package passed in a -L/lib, and
the linker caught this and issued a warning.

The fix is to figure out why the configuration file attempted to pass -L/lib,
and stop it from occurring.

Please file a bug on the log message being confusing and I'll attempt to get
that fixed.. (or a patch)  ;)

Done, thanks.  http://bugzilla.pokylinux.org/show_bug.cgi?id=702

Now to figure out how to fix it :-)
