Original GitHub issue: https://github.com/debauchee/barrier/issues/52

Operating Systems

Gentoo Linux

Barrier Version

2.1.0

Steps to reproduce bug

cd /path/to/barrier
mkdir build
cd build
cmake -DBARRIER_BUILD_GUI=OFF -DBARRIER_BUILD_INSTALLER=OFF ../

If I do not have any provider of dns_sd.h installed (such as mdnsresponder or avahi with mdnsrespondercompat) cmake aborts with: "Missing header: dns_sd.h"

Expected result: cmake will succeed as long as BARRIER_BUILD_GUI=OFF, despite the lack of a provider of dns_sd.h on my system. With BARRIER_BUILD_GUI=ON cmake will complain about missing dns_sd.h

Other info

The only files that include dns_sd.h are under src/gui/src, thus it seems that dns_sd is only a requirement when building the GUI. This also reflects the state of things for old versions of synergy.

Further I ended up installing avahi and building with GUI and I checked the output of ldd on the resulting binaries:
barrier-ldd.txt
Only the GUI executable "barrier" shows any dependency on libdns_sd.so.1, libavahi-client.so.3 and libavahi-common.so.3

I could be wrong, but I think barrier needs dns_sd.h whether you're building the GUI or not.

synergy-1.9 doesn't, and judging from the barrier source code and the resulting binaries it shouldn't need it as well.
