Re: [Ltib] Can we use /opt/freescale/ltib/usr/bin/pkg-config in spec files invoking autotools ?

[Stuart Hughes]

Hi Franz,

You need to look at the package itself (in configure) to see how it is 
doing the test that's failing.  Often you'll find packages that are not 
cross-compiler aware.  If that is the case, you have to pre-stuff the 
result with something like:

ac_cv.... ./configure

Take a look at some of the existing .spec files to get an idea.

Note also, you should also pass  --host in your configure line (see 
template.spec).  It should be something like:

%Build
./configure --prefix=%{_prefix} --host=$CFGHOST --build=%{_build}
make

Regards, Stuart
