Re: [Ltib] Calling Native toolchain as well as target toolchain inmakefile.

[Stuart Hughes]

Hi Mark,

Using $BUILDCC is the right way to call up the host based compiler.
However you'll need to look at the Makefiles for libgpg-error to see if
it is cross compiler aware (e.g. has some provision for building some
parts with one compiler and some another).  If it has, then use whatever
it requires, often this is CC_FOR_BUILD="$BUILDCC" (note the quote but
sometimes it's HOSTCC="$BUILDCC", it depends on the package.  If the
package is not cross compiler aware then you'll need to make a patch so
that it is.

One thing, normally Makefile.am should not need to be worried about as
this only gets processed when you run 'automake' ? 

Have you got a spec file you can send me for this package?  If you can't
get it working easily let me know, maybe I can take a look.

Regards, Stuart
