Has anyone done any work with compiling CODEC2 onto dsPIC?
I do not want to waste any time reinventing the wheel if someone has
already done this.
Many thanks,

Hello,
I have just checked in a bug fix (svn rev 1162) in the modem QPSK
mapping pointed out by Bill Cowley:
http://www.rowetel.com/blog/?p=2851#comment-65484
This means that the modem will be incompatible with the previous modem
code, but has a significantly improved bit error rate. So if you are
building FreeDV from source using rev 1162 or later it won't talk to
previous versions of FreeDV, such as the current V0.91 beta release.
When we do a new release we will need to work out a way to help people
thru this incompatibility.
Cheers,
David

Hello Samuel,
Codec 2 uses floating point so at this stage won't run efficiently on a
fixed point DSP.
Cheers,
David

David,
I think the community is still small and localized enough that we can
have a flag day. We will announce that after a certain date we expect
everyone to use the new binary on the air.
This time. We need a better method next time.
Thanks
Bruce

Hello Everyone,
Just following up on my 12/24/2012 thread but I just updated the FreeDV
sources but it seems that the most current FreeDV sources still won't
compile on my Linux setup. Any ideas on how to get past the libctb test
for a 64bit Centos6 distro? I'm still getting:

I've tried both:
export CXXPATH="/usr/include/ctb-0.16/"
and
export LDPATH="/usr/include/ctb-0.16/"
and then re-running ./configure without any improvements. Could this
be a 64bit issue?
Any ideas?
Ps. Below is from my previous email as well. It might matter but I'm
not sure

Take the opportunity now to make the change. Once FreeDV & CODEC2 hit Dayton
and hopefully spread widely, it will be much harder to switch over.
