Hi David,
After I upgraded to the latest distribution of Debian, I could install
Codec2 and run the test files.
I also installed sox to get play command.
When I tried to install LPC-net, I got several errors, starting with a
warning at nnet.c:49:2 Compyling without vectorization
and then when building liblpcnetfreedv.so: undefined reference to
'c2const_create'
after that the building stopped.
After all - not so bad for my limited Linux knowledge, I think.
Regards
Gerhard OE3GBB
