Make the docker-related logic for doing a local packaged build on Linux match
with the Jenkins CI build for Linux.
Also fix the problems with packaged builds for Linux (local or CI) where
gstreamer errors were displayed in the terminal shortly after app start/login
and there was no sound output.
Replaces PR #105.
Implement a `pkg-macos` target that ultimately results in `Status.dmg` being
written to `pkg/`. Due to [limitations][limits] of the OpenSSL `.dylib`s in
`/usr/lib/` on macOS, `libssl.a` and `libcrypto.a` are statically linked into
`bin/nim_status_client` from a [Homebrew][brew] "bottle" that is compatible
with macOS 10.13 (the oldest macOS version compatible with Qt v5.14).
`pkg-macos` creates an `.app` bundle layout in `tmp/macos/dist` based partly on
information in a very helpful [StackOverflow answer][so-answer]. Note the part
of the answer (toward the end) that explains a problem with the working
directory and how to fix it. That's the reason for the `nim_status_client.sh`
script introduced in this commit (it gets copied into the bundle). It's also
the reason for having `Info.plist` copied into the bundle before `macdeployqt`
is run (see below) and then overwriting it with `Info.runner.plist` before
creating the `.dmg` file. The app icons file `status-icon.icns` was taken from
`deployment/macos/` in the [status-react][sr] repo.
The [`macdeployqt`][macdeployqt] tool is used to copy the needed portions of Qt
into the bundle; it automatically updates `rpath`, etc. so the
`nim_status_client` executable in the bundle can locate the libs within the
bundle.
`macdeployqt` is run twice, for the "outer" and "inner" `.app` bundles,
because of an apparent bug in `macdeployqt` that results in QtWebEngine related
resources not being processed correctly on the first pass. This results in some
bloat in the final bundle but it seems unavoidable at present.
The [create-dmg][cdmg] tool is used to package the bundle into a `.dmg`
file. There are two reasons for this:
1. It produces a nice looking icon for the `.dmg` that overlays the Status logo
on an external disk icon.
2. `Info.plist` needs to be overwritten after running `macdeployqt` (see
explanation above) but before creating the `.dmg` file. If we passed the `-dmg`
cli option to `macdeployqt` to have it generate the `.dmg` file then it
wouldn't be possible to overwrite `Info.plist`.
So there is a cosmetic reason and a practical reason for using another
tool. Probably the biggest downside is that `create-dmg` is implemented in
Node.js so it needs to be installed with `npm`; that's the reason this commit
introduces `package.json`, etc. Note that zero code from `node_modules` ends up
in the `.app` bundle or the `.dmg` file.
Code signing of the macOS `.app` bundle and `.dmg` is attempted if the
environment variable `MACOS_CODESIGN_IDENT` is defined. In that case, the
environment variable `MACOS_KEYCHAIN_OPT` may optionally be defined with the
path to a preferred keychain database file.
Refactor a number of sections in the Makefile for consistency's sake, e.g. the
`appimage` target becomes `pkg-linux` and ultimately results in
`NimStatusClient-x86_64.AppImage` being written to `pkg/`.
Make a number of changes to bring the Linux packaging steps up-to-date and use
the `-qmlimport` cli option of `linuxdeployqt` to simplify resolution of Qt
plugins.
Note that `make pkg` will correctly resolve to `make pkg-linux` or `make
pkg-macos` depending on the OS in use.
Consistently use lower-case "c" in the name of *components* directories and
imports.
