Building
|
||||
---
|
||||
To build Proton for Linux, set up a Debian machine with the Steam runtime and
|
||||
chroots as documented in the Steam Runtime repository:
|
||||
The following instructions describe how we create the build environment for the
|
||||
production builds of Proton. For reproducibility and security reasons, we build
|
||||
inside of a Debian 9 virtual machine. However, you should be able to follow
|
||||
these instructions on other distributions as well.
|
||||
|
||||
<https://github.com/ValveSoftware/steam-runtime>
|
||||
The Steam Runtime provides a clean and consistent set of libraries. Software
|
||||
distributed through Steam should depend only on libraries available through the
|
||||
runtime, and so we build in that environment for production Proton builds.
|
||||
However, if you are simply making a build for yourself, you can skip the Docker
|
||||
and Steam Runtime setup steps below, as they take a very long time to set up.
|
||||
At configure-time, pass the `--no-steam-runtime` flag instead of the Docker
|
||||
flags shown here.
|
||||
|
||||
In addition, you will need to install gcc-5 and a long list of dependencies
|
||||
required for Wine. The following set of commands is an example session, and may
|
||||
not be complete.
|
||||
The build system uses Docker containers. It requires your user to be able to
|
||||
usefully run Docker containers, which generally means [your user needs to be in
|
||||
the "docker" group](https://docs.docker.com/install/linux/linux-postinstall/),
|
||||
which can have [security
|
||||
implications](https://docs.docker.com/engine/security/security/).
|
||||
|
||||
Starting from a stock Debian 9 installation, you will need to install the
|
||||
`gpgv2`, `gnupg2`, `g++`, and `g++-6-multilib` packages from the
|
||||
Debian repos. You will also need to install `meson` version 0.43 or later,
|
||||
which can be [acquired from backports](https://backports.debian.org/Instructions/). Next,
|
||||
[install Docker-CE from the official Docker repositories](https://docs.docker.com/install/linux/docker-ce/debian/).
|
||||
Finally, since we will need to be able to run Wine during the build process,
|
||||
[install the `winehq-devel` package from the official WineHQ repositories](https://wiki.winehq.org/Debian).
|
||||
This will pull in all of the dependencies required to run wine. You can then
|
||||
(and we do) uninstall the `winehq-devel` package in order to ensure that a
|
||||
system Wine installation does not interfere with your build process.
|
||||
|
||||
Next we set up the Steam runtime build environments. Here we use the
|
||||
`wip-docker` branch to get access to the Docker images.
|
||||
|
||||
cd ~
|
||||
git clone https://github.com/ValveSoftware/steam-runtime.git
|
||||
cd steam-runtime
|
||||
#install the end-user steam runtime:
|
||||
./build-runtime.py
|
||||
#install the 32-bit scout_beta runtime:
|
||||
./setup_chroot.sh --beta --i386
|
||||
#enter the 32-bit runtime:
|
||||
schroot --chroot steamrt_scout_beta_i386
|
||||
git checkout -b wip-docker origin/wip-docker
|
||||
|
||||
This will enter the chroot environment, where you would issue the following commands:
|
||||
The steps below will build the Docker images. Each step will take a significant
|
||||
amount of time. Note the path to a file in the `proton` directory. See the
|
||||
previous section for instructions on cloning Proton.
|
||||
|
||||
sudo apt-get install gcc-5 g++-5 g++-5-multilib flex bison libosmesa6-dev libpcap-dev libhal-dev libsane-dev libv4l-dev libgphoto2-2-dev libcapi20-dev libgsm1-dev libmpg123-dev libvulkan-dev libxslt1-dev nasm yasm
|
||||
sudo update-alternatives --install `which gcc` gcc `which gcc-5` 50
|
||||
sudo update-alternatives --set gcc `which gcc-5`
|
||||
sudo update-alternatives --install `which g++` g++ `which g++-5` 50
|
||||
sudo update-alternatives --set g++ `which g++-5`
|
||||
sudo update-alternatives --install `which cpp` cpp-bin `which cpp-5` 50
|
||||
sudo update-alternatives --set cpp-bin `which cpp-5`
|
||||
exit
|
||||
cd ~
|
||||
#set up the 64-bit Docker image for building Proton
|
||||
./steam-runtime/setup_docker.sh --beta amd64 --extra-bootstrap=./proton/steamrt-bootstrap.sh steam-proton-dev
|
||||
#set up the 32-bit Docker image for building Proton
|
||||
./steam-runtime/setup_docker.sh --beta i386 --extra-bootstrap=./proton/steamrt-bootstrap.sh steam-proton-dev32
|
||||
|
||||
Next, you need to repeat the process, but for amd64:
|
||||
With the build system set up, we can configure Proton and kick off the build.
|
||||
If you are not building in the runtime, pass `--no-steam-runtime` to
|
||||
`configure.sh` instead.
|
||||
|
||||
./setup_chroot.sh --beta --amd64
|
||||
schroot --chroot steamrt_scout_beta_amd64
|
||||
mkdir proton/mybuild/
|
||||
cd proton/mybuild
|
||||
../configure.sh --steam-runtime64=docker:steam-proton-dev --steam-runtime32=docker:steam-proton-dev32
|
||||
make -j6 all dist
|
||||
|
||||
And then repeat all of the commands to install gcc and Wine dependencies again.
|
||||
|
||||
In addition, your host system will need to be able to run Wine in both 64-bit and
|
||||
32-bit modes in order to create the default prefix. It is recommended to
|
||||
install Wine from your package manager, including its optional dependencies.
|
||||
|
||||
The openal-soft build system requires cmake 3.0.2 or later, which is newer than
|
||||
the Steam runtime SDK provides. You will need to build and install a newer
|
||||
cmake into each of the runtimes. For convenience, the build_proton.sh script
|
||||
will attempt to use cmake from ~/opt32/bin/ and ~/opt64/bin/, if available.
|
||||
|
||||
The following example session obtained and built cmake:
|
||||
|
||||
cd /tmp
|
||||
wget https://cmake.org/files/v3.11/cmake-3.11.4.tar.gz
|
||||
schroot --chroot steamrt_scout_beta_i386
|
||||
tar -xzf cmake-3.11.4.tar.gz
|
||||
cd cmake-3.11.4
|
||||
./configure --parallel=4 --prefix=~/opt32
|
||||
make -j 4 && make install
|
||||
exit
|
||||
rm -rf cmake-3.11.4
|
||||
schroot --chroot steamrt_scout_beta_amd64
|
||||
tar -xzf cmake-3.11.4.tar.gz
|
||||
cd cmake-3.11.4
|
||||
./configure --parallel=4 --prefix=~/opt64
|
||||
make -j 4 && make install
|
||||
exit
|
||||
|
||||
|
||||
Finally, change your directory back to proton, and run:
|
||||
|
||||
cd ../proton
|
||||
./build_proton.sh
|
||||
|
||||
That should configure and build Wine, and then package the result up into
|
||||
<tt>dist/</tt>. It is important to examine the output near the end of
|
||||
<tt>build/wine.win{64,32}/config.log</tt> to ensure that you have all of the relevant
|
||||
libraries in each chroot. Search for '<tt>executing Makefile commands</tt>' in
|
||||
<tt>config.log</tt> to find messages about missing libraries. It is normal to be missing
|
||||
a few libraries, including OpenCL, OSS, and libav.
|
||||
|
||||
**NOTE:** The build_proton.sh script builds most components inside the Steam runtime
|
||||
chroot. However, dxvk will not build in that environment, so the build_proton.sh
|
||||
script will build it on your local system. This will require you to be able to
|
||||
build dxvk on your local system; refer to [the dxvk README.md](https://github.com/ValveSoftware/dxvk/blob/master/README.md) for more details.
|
||||
**Tip**: If you are building without the Steam runtime as shown here, you
|
||||
should first run `make obj-wine64/Makefile obj-wine32/Makefile` and check the
|
||||
files `obj-wine64/config.log` and `obj-wine32/config.log` for missing packages.
|
||||
Search for `won't be supported`. A couple of missing packages are normal:
|
||||
`opencv`, `gstreamer`, `vkd3d`, `oss`, and `libavcodec`. More than that may
|
||||
indicate a problem. One easy way to install the dependencies required to build
|
||||
Wine is to use `apt-get`'s `build-dep` feature.
|
||||
|
||||
The `mybuild/dist` folder now contains a build of Proton which you can install
|
||||
manually or with `make install` to install into your user's Steam installation.
|
||||
See the next section for more details.

||||
Deploying
|
||||
---
|
||||
Once built, the <tt>dist/</tt> directory will contain the files which can be distributed
|
||||
through Steam. For testing purposes, you should be able to clear out the files
|
||||
in your <tt>steamapps/common/Proton</tt> directory and replace them with the contents of
|
||||
<tt>dist/</tt>. The <tt>proton</tt> script will unpack the files on first run. Note that if you
|
||||
use the Steam client to verify local files, it will restore the production version
|
||||
of Proton.
|
||||
Steam ships with several versions of Proton, which games will use by default or
|
||||
that you can select in Steam Settings's SteamPlay page. Steam also supports
|
||||
running games with local builds of Proton, which you can install on your
|
||||
machine.

|

submodule and directory for details.
|
||||
To install a local build of Proton into Steam, make a new directory in
|
||||
`~/.steam/steam/compatibilitytools.d/` with a tool name of your choosing and
|
||||
place the contents of `dist` into that folder. The `make install` target will
|
||||
perform this task for you, installing the Proton build into the Steam folder
|
||||
for the current user. You will have to restart the Steam client for it to pick
|
||||
up on a new tool.
|
||||
|
||||
A correct local tool installation should look like this:
