Headless build does not enable OSC correctly (aarch64)

[riban-bw]

Building an aarch64 headless will create standalone executeables that do not properly enable OSC control.

See issue #557 for details of build process but in summary:

sudo apt install tmux build-essential git libdbus-1-dev libgl1-mesa-dev liblo-dev libmagic-dev libsndfile1-dev libx11-dev libxcursor-dev libxext-dev libxrandr-dev python3 libarchive-dev libjansson-dev libsamplerate0-dev libspeexdsp-dev libdbus-1-dev libgl1-mesa-dev liblo-dev libmagic-dev libsndfile1-dev libx11-dev libxcursor-dev libxext-dev libxrandr-dev cmake wget
git clone --recursive https://github.com/DISTRHO/Cardinal.git
cd Cardinal
make -j4 HEADLESS=true SYSDEPS=true STATIC_BUILD=true # intermediate step required due to build issue https://github.com/DISTRHO/Cardinal/issues/557
make -j4 HEADLESS=true SYSDEPS=true # Rebuild stand alone executables fixing issue connecting to audio server (jack/alsa)
sudo make install

Running Cardinal results in:

It is expected that OSC is enabled and IP port open but logging shows:

OSC Remote control is available on request

This is due to the use of STATIC_BUILD which undefines CARDINAL_INIT_OSC_THREAD. So I need to find a way to build without the intermediate step in #557.

For now I have removed the undefine from CardinalCommon.cpp and see UDP port 2228 available. OSC here I come...

this is an invalid issue, static build is an internal macro not for public use, it skips the use of things that would make a glibc static build impossible (which means jack support and liblo/osc/network stuff).

a static build failing to use network things is just expected, it is what it is intended to do after all.

the issue should be about solving the build problem, lets keep discussion on that. this ticket by itself is invalid, and thus I will close that now
