Compilation Failure ubuntu Impish

[wx4cb]

followed all the directions as per buster, changed the debian.control file to have debhelper instead of dh-systemd.

seems to compile ok for the most part, but i get the following errors art the end of the compile

i have rtl-sdr compiled from source so it appears it's looking for the rtl package which isnt obviously installed ?

Yeah, you need a correctly packaged version of librtlsdr-dev installed to do a package build of dump1090. If you also have a compiled-from-source version present, that will interfere with the build.

i found a work aroudn for this. basically to get shlib to ignore failed dependencies and got it installed and running

[mutability]

Sure. Be aware that the error is intentional; if you disable the check then you'll end up with a package that has linked against a library that the package management system knows nothing about, and so you'll run into unexpected runtime problems if that library is ever changed or removed (or if you try to install the built package on a different system)
