Hi Michael,
A short while ago, I installed 3.7.2.1 from your macports
implementation. The install went without trouble, and
I've been composing and running flowgraphs from GRC
with no issues.
I recently tried to port one of my custom blocks up to
the 3.7 api, and I encountered problems. In order
to try and eliminate as much as possible, I tried creating
a new gr-howto module, as per the tutorial. It succeeds
the cmake but fails make during the link stage.
The first few errors emitted are
==================

square_ff_impl.cc.o
...
====================
It would seem to be a boost problem. Port shows me as
having boost 1.55.0 installed.
The same exact module makes fine on a different system
running 3.7.2.1 under Ubuntu 12.04lts.
Any ideas? Thanks!
