I tried to compile the api3 branch on my Arch Linux System, but got a lot of errors like this:

gcc -g -o dump1090 dump1090.o anet.o interactive.o mode_ac.o mode_s.o net_io.o crc.o demod_2000.o demod_2400.o demod_8000.o stats.o cpr.o icao_filter.o track.o util.o convert.o dump1090.h -L./ -lsdrplay_api -lpthread -lm -lrtlsdr  -lrt `pkg-config --libs librtlsdr`

I have searching in the internet and tried a lot but was not able to fix the Problem.

Please see my post on issue API3 version compile error #6 It tries to explain the error, but we need a programmer to fix it.

If you have a Raspberry Pi or an older OS that you can boot to, see API3 version compile error #6 I managed to get it to work.

Thank you for the information, but I think the problem has to be fixed in the source code by the owner.

How did you do it? The source code branch cloned by this command hasn't been changed in 2 years. git clone https://github.com/SDRplay/dump1090 -b api3

Recently, I had the same multiple definition errors when compiling this code with gcc 10.2.1 The older version in Debian buster did not have the problem.

Sorry for the delay on sorting this...

The repo has been cleaned up and now the master branch supports API3 and should build correctly. The README.md has been updated with better instructions and the Makefile has some additional comments.

Best regards,
