Hi all, On a pristine new build of Ubuntu 18.04 on a Pentium Intel(R) Pentium(R) CPU G4560 @ 3.50GHz (which has no AVX/AVX2 extensions because the bloke in the PC shop has no idea what does and doesn't) anyway, Downloading LPCnet git clone https://github.com/drowe67/LPCNet the build requires codec2 BUT, codec2 also requires LPCnet. git clone -b brad-2020 https://github.com/drowe67/codec2 Do make install here, then go back, do LPCnet, go back to Codec2 mod the CMakeLists.txt file, add the location of LPCnet (about line 133, add a "set" line) mkdir new_build_dir and make install again.
git clone -b brad-2020 https://github.com/drowe67/freedv-gui And it looks to be working but with no AVX/AVX2 the CPU load is heavy, 115% though in 700D mode it's 105% according to "top". Running with remote display ( ssh -Y user@host ) "top" reports only 50% CPU usage on the Pentium G4560 box, mode 2020. And, the box draws 32 Watts. Not bad. It's an Asus H110M-A m/b with 8Gb ram and a 2Tb hard disk. Next to connect the radio. The audio device, A VOLANS VL-UA01 Keep smiling Alan VK2ZIW On Sun, 19 May 2019 21:38:18 +1000, Al Beard wrote > Hi all, > > Apologies, some of my problems have been in compiling the codec2 2020 > library, not specifying where LPCnet was located.
