Subject: [PATCH 1/6] Eliminate protobuf AddDescriptors() call.
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|
|
|
|
Eliminating protobuf's AddDescriptors() calls enabled
|
|
forward-compatibility with libprotobuf. That allows to
|
|
run OLA on recent Linux distrubutions.
|
|
|
|
Tested on x86_64 running Fedora 27 with protobuf 3.3.1
|
|
in combination with QLC+ and a uDMX controller.
|
|
|
|
See #1192.
