+# Cross-compile from Linux
+
+## Intro
+
+Following these instructions you will be able to cross-compile qTox to Windows.
+
+This script can be used by qTox power users to cross-compile qTox themselves,as
+ well as by qTox developers to make sure their local changes don't break
+cross-compilation to Windows.
+
+Note that the compilation script doesn't build the updater and doesn't produce
+an installer.
+
+## Usage
+
+[Install Docker](https://docs.docker.com/engine/installation/linux/).
+
+You should have 3 directories available (names don't have to match the given
+ones):
+
+1. `workspace` -- a directory that will contain a cache of qTox dependencies
+and the final qTox cross-compilation build. You should create this directory.
+2. `script` -- a directory that contains the `build.sh` script. You can use
+this directory for this, there is no need to create a new one.
+3. `qtox` -- a root directory of a qTox repository. This directory contains
+qTox source code that will be cross-compiled. You can use the root of this qTox
+repository, there is no need to create a new one.
+
+These directories will be mounted inside a Docker container at `/workspace`,
+`/script` and `/qtox`.
+
+The contents of `qtox` and `script` directories wouldn't be modified. The
+`build.sh` script actually makes a copy of `qtox` directory and works on that
+copy.
+
+Once you sort out the directories, you are ready to run the `build.sh` script
+in a Docker container.
+
+Note that the `build.sh` script takes 2 arguments: architecture and build type.
+Valid values for the architecture are `i686` for 32-bit and `x86_64` for
+64-bit. Valid values for the build type are `release` and `debug`. All case
+sensitive.
+
+Now, to start the cross-compilation, for example, for a 32-bit release qTox, run
+
+```sh
+sudo docker run --rm \
+                -v /absolute/path/to/your/workspace:/workspace \
+                -v /absolute/path/to/your/script:/script \
+                -v /absolute/path/to/your/qtox:/qtox \
+                ubuntu:16.04 \
+                /bin/bash /script/build.sh i686 release
+```
+
+If you are a qTox developer, you might want to instead run
+
+```sh
+# Get shell inside Ubuntu 16.04 container so that you can poke around if needed
+sudo docker run -it \
+                --rm \
+                -v /absolute/path/to/your/workspace:/workspace \
+                -v /absolute/path/to/your/script:/script \
+                -v /absolute/path/to/your/qtox:/qtox \
+                ubuntu:16.04 \
+                 /bin/bash
+# Run the script
+bash /script/build.sh i686 release
+```
+
+This will cross-compile all of the qTox dependencies and qTox itself, storing
+them in the `workspace` directory. The first time you run it for each
+architecture, it will take a long time for the cross-compilation to finish, as
+qTox has a lot of dependencies that need to be cross-compiled. It takes my
+Intel Core i7 processor about 125 minutes for the cross-compilation to get done
+on a single core, and about 30 minutes using all 8 hyperthreads. But once you
+do it once for each architecture, the dependencies will get cached inside the
+`workspace` directory, and the next time you build qTox, the `build.sh` script
+will skip recompiling them, going straight to compiling qTox, which is a lot
+faster -- about 8 minutes on a single core and 2 minutes using 8 hyperthreads.
+
+The structure of `workspace` directory that the `build.sh` script will create
+is as follows:
+
+```
+workspace
+├── i686
+│   ├── dep-cache
+│   │   ├── libffmpeg
+│   │   ├── libfilteraudio
+│   │   ├── libopenal
+│   │   ├── libopenssl
+│   │   ├── libopus
+│   │   ├── libqrencode
+│   │   ├── libqt5
+│   │   ├── libsodium
+│   │   ├── libsqlcipher
+│   │   ├── libtoxcore
+│   │   └── libvpx
+│   └── qtox
+│       ├── debug
+│       └── release
+└── x86_64
+    ├── dep-cache
+    │   ├── libffmpeg
+    │   ├── libfilteraudio
+    │   ├── libopenal
+    │   ├── libopenssl
+    │   ├── libopus
+    │   ├── libqrencode
+    │   ├── libqt5
+    │   ├── libsodium
+    │   ├── libsqlcipher
+    │   ├── libtoxcore
+    │   └── libvpx
+    └── qtox
+        ├── debug
+        └── release
+```
+
+The `dep-cache` directory is where all cross-compiled qTox dependencies will be
+cached for the future runs. You can remove any directory inside `deps`, which
+will result in the `build.sh` re-compiling the missing dependency.
+
+The `qtox` directory, split into `debug` and `release`, is where the
+cross-compiled qTox will be stored.

+# Known issues:
+# - Doesn't build qTox updater, because it wasn't ported to cmake yet and
+#   because it requires static Qt, which means we'd need to build Qt twice,
+#   and building Qt takes really long time.
+#
+# - Doesn't create an installer because there is no NSIS 3 in Ubuntu. We could
+#   switch to Debian instead and backport it from Experimental, which is what
+#   we do on Jenkins, but since we don't build an updater, we might as well
+#   just do the nightly qTox build: no updater, no installer.
+#
+# - Qt from 5.8.0 to 5.9.1 doesn't cross-compile to Windows due to
+#   https://bugreports.qt.io/browse/QTBUG-61740. Should be fixed in 5.9.2. You
+#   can easily patch it though, just one sed command, but I guess we will wait
+#   for 5.9.2.
+#
+# - FFmpeg 3.3 doesn't cross-compile correctly, qTox build fails when linking
+#   against the 3.3 FFmpeg. They have removed `--enable-memalign-hack` switch,
+#   which might be what causes this.
+#
+# - Toxcore v0.1.9 doesn't cross-compile to Windows due to a linking order
+#   issue in monolith_test https://github.com/TokTok/c-toxcore/pull/564. It's
+#   fixed in master, so we just wait checking out a stable master commit point
+#   until the next release. Once the next release occurs, we will be checking
+#   out that instead.
