Unable to build under Ubuntu 20

I'm assuming that 'uhd' version is incompatible. Currently in my system it is libuhd3.15.0. Any ideas which version is compatible?

Hi Juliusz, I had a little time to play with this, this evening, and I didn't get as far as you did.  I'm using Ubuntu 20.10.  Are you using 20.04?  I ran into a problem duo to moving to GCC 10.  The new default to -fno-common is causing a lot of problems with the softrock directory at least.  Here is a link to some data on that. <https://gcc.gnu.org/gcc-10/porting_to.html>  I haven't fixed the issue.  I'm not enough of a C expert to say if the best fix is to add -fcommon or to add externs to the definitions in the header files.  I lean toward the latter.   Here is a sample of the issues I'm getting. /usr/bin/ld: softrock-listener.o:/home/frohro/Projects/ghpsdr3-alex/trunk/src/softrock/receiver.h:60: multiple definition of `receiver'; softrock-client.o:/home/frohro/Projects/ghpsdr3-alex/trunk/src/softrock/receiver.h:60: first defined here I was able to fix the errors in the softrock directory by putting "extern" in the .h files and then declaring them in a .c file. There are a whole bunch more similar errors in the dspserver directory, but it's bedtime, so I won't have time to do those fixes tonight. It looks like most of the developers of this system are no longer using it.  Even I haven't tried to compile it since Ubuntu 18.04. 73, Rob KL7NA

Hi Rob!

Yeah... I'm using Ubuntu 20.04 so did not encountered problems with gcc which you have described. Gcc version here is 9.3.0. The only issue I've experienced was (besides one described here ;)) this one -> #55.

I'm sad because I had hope to use ghpsdr3 under Linux with Apache Labs Anan 10 SDR, but it looks like that whether you are not a Windows user It is only expensive paper clip...

Hi Juliusz, I am working on my version of ghpsdr to get my ANAN10-E working. I have got it mostly working with firmware version 1.50.  It's not ready for release yet due to some bugs I need to track down.  I do however recommend John Melton's G0ORX latest software for Linux LINHPSDR and PIHPSDR available on GitHub. 73 Rick KD0OSS

Hi Juliusz, I finished fixing all the -fno-common problems, and it builds fine for me now.  I'm not having your trouble with my new install of Ubuntu 20.10.  I committed the changes to the repository <https://github.com/alexlee188/ghpsdr3-alex>. Perhaps you could tell me the process you went through to build it. 73, Rob KL7NA
