3 years ago 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.
