@ -49,14 +49,23 @@ you can figure out how the next command should look like. In my case it's:
.. code-block:: bash
pkgscripts-ng/EnvDeploy -p armada38x -v 6.2
cp /etc/ssl/certs/ca-certificates.crt /build_env/*/etc/ssl/certs/
Now we can build an SPK package:
The second command is very important, or the package build will fail on SSL
errors. Now we can build an SPK package:
.. code-block:: bash
pkgscripts-ng/PkgCreate.py -p armada38x -v 6.2 -S --build-opt=-J --print-log -c WireGuard
There should now be an SPK in ``/result_spk``
There should now be an SPK in ``/result_spk``. You can now exit the docker
container and extract the SPKs:
.. code-block:: bash
sudo docker cp synobuild:/result_spk/WireGuard-0.0.20190227/WireGuard-armada38x-0.0.20190227.spk .
