Well, it looks like I can answer my own question. I found the following
passage in the gnu assembler manual:
-
The way the required alignment is specified varies from system to system.
For the a29k, hppa, m68k, m88k, w65, sparc, Xtensa, and Renesas / SuperH

Hi everybody,
I am trying to build gnuradio-core on Darwin 8.6.1 on an Intel processor
(MacBook Pro). (Has anybody done this yet? I couldn't find any references
through Google). I started with Jon Jacky's excellent instructions and got
all the prerequisites straightened out (I think).
Where I get

I've been attempting to get my LFRX daughterboard working on a USRP
board. Most of the gnuradio-examples I've tried don't work on the LFRX

Ok, just
Since there's been a lot of talk about GUIs and graphical programming,
I'll describe some of the work I've been doing. I'm using a graphical
modeling tool called Ptolemy to allow design of gnuradio systems.
Here is the basic approach:
1) Automatically scan gnuradio source tree and build XML

Hello,
I was just wondering if anyone has used GNURadio for any non-radio
applications, specifically phone line modulation/demodulation.
It shouldn't be too difficult to design a daughter board for the USRP to
sample phone line voltage (with an appropriate line interface circuit of
course). Afte
Hello!
Reading the post about Googles's SoC it reminded me of an idea had for
quite a while:
Imagine a graphical interface to Gnuradio where all python blocks are
represented by some widget, with name, parameters, description/doc and
the like. On the left side fo an widget you've some dockin

Yes, if it's based on gr_block and you call consume or consume_each
in general_work.
