Eric,

Thanks for the review!

And thank you for the specific pointers as well, they probably saved
me a lot of time.

Now, I decided to go for a slightly different approach that seemed
more straightforward. The ‘lame’ example seems to be aimed more at
the build architecture than the target's. My understanding of such
intricacies is still quite limited so someone please double-check.

Unless someone's using their Raspberry Pi to cross-compile for their
i7, I suspect the difference is theoretical.

I'm afraid you lost me here.

   $ grep lbz2 Makefile
   LIBS = -llzo2 -lbz2 -lz -lm -lpthread

In fact, the ./configure check is (probably incorrectly) non-fatal so
the build doesn't fail until you call ‘make’.

Building with ‘bzip2’ results in a correctly statically-linked
BZ2_bzBuffToBuffCompress(), so I don't see what other type of (input)
this could be. Surely not native?

That would totally break the i7 gal's build.

Will do!

Kind regards,
