# Platforms
You should be able to compile Aseprite successfully on the following
platforms:
* Windows 10 + VS2015 Community Edition + Windows 10 SDK
* macOS 10.12.1 Sierra + Xcode 8.0 + macOS 10.12 SDK + Skia
* Linux + gcc 4.8 with some C++11 support
# Get the source code
You can get the source code downloading a `Aseprite-v1.x-Source.zip`
file from the latest Aseprite release:
https://github.com/aseprite/aseprite/releases
Or you can clone the repository and all its submodules using the
following command:
git clone --recursive https://github.com/aseprite/aseprite.git
To update an existing clone you can use the following commands:
cd aseprite
git pull
git submodule update --init --recursive
You can use [Git for Windows](https://git-for-windows.github.io/) to
clone the repository on Windows.
# Dependencies
To compile Aseprite you will need:
* The latest version of [CMake](http://www.cmake.org/) (3.4 or greater)
* [Ninja](https://ninja-build.org) build system
Aseprite can be compiled with two different back-ends:
1. Allegro back-end (Windows, Linux): You will not need any extra
library because the repository already contains a modified version
of the Allegro library. This back-end is deprecated and will be
removed in future versions. All new development is being done in
the new Skia back-end.
2. Skia back-end (Windows, macOS): You will need a compiled version
of the Skia library. Please check the details about
[how to build Skia](#building-skia-dependency) on your platform.
## Windows dependencies
First of all, you will need an extra little utility: `awk`, used to
compile the libpng library. You can get this utility from MSYS2
distributions like [MozillaBuild](https://wiki.mozilla.org/MozillaBuild).
After that you have to choose the back-end:
1. If you choose the Allegro back-end, you can jump directly to the
[Compiling](#compiling) section.
2. If you choose the Skia back-end, you will need to
[compile Skia](#skia-on-windows) before and then continue in the
[Compiling](#compiling) section. Remember to check the
[Windows details](#windows-details) section to know how to call
`cmake` correctly.
## macOS dependencies
On macOS you will need macOS 10.12 SDK and Xcode 8.0 (older versions
might work).
Also, you must compile [Skia](#skia-on-macos) before starting with
the [compilation](#compiling).
## Linux dependencies
You will need the following dependencies (Ubuntu, Debian):
sudo apt-get update -qq
sudo apt-get install -y g++ libx11-dev libxcursor-dev cmake ninja-build
The `libxcursor-dev` package is needed to
[hide the hardware cursor](https://github.com/aseprite/aseprite/issues/913).
# Compiling
1. [Get Aseprite code](#get-the-source-code), put it in a folder like
`C:\aseprite`, and create a `build` directory inside to leave all
the files that are result of the compilation process (`.exe`,
`.lib`, `.obj`, `.a`, `.o`, etc).
cd C:\aseprite
mkdir build
In this way, if you want to start with a fresh copy of Aseprite
source code, you can remove the `build` directory and start again.
2. Enter in the new directory and execute `cmake`:
cd C:\aseprite\build
cmake -G Ninja ..
Here `cmake` needs different options depending on your
platform. You must check the details for
[Windows](#windows-details), [macOS](#macos-details), and
[Linux](#linux-details). Some `cmake` options can be modified using tools like
[`ccmake`](https://cmake.org/cmake/help/latest/manual/ccmake.1.html)
or [`cmake-gui`](https://cmake.org/cmake/help/latest/manual/cmake-gui.1.html).
3. After you have executed and configured `cmake`, you have to compile
the project:
cd C:\aseprite\build
ninja aseprite
4. When `ninja` finishes the compilation, you can find the executable
inside `C:\aseprite\build\bin\aseprite.exe`.
## Windows details
To choose the Skia back-end
([after you've compiled Skia](#skia-on-windows)) you can execute `cmake`
with the following arguments:
cd aseprite
mkdir build
cd build
cmake -DUSE_ALLEG4_BACKEND=OFF -DUSE_SKIA_BACKEND=ON -DSKIA_DIR=C:\deps\skia -G Ninja ..
ninja aseprite
In this case, `C:\deps\skia` is the directory where Skia was compiled
as described in [Skia on Windows](#skia-on-windows) section.
## macOS details
After [compiling Skia](#skia-on-macos), you should run `cmake` with
the following parameters and then `ninja`:
cd aseprite
mkdir build
cd build
cmake \
-DCMAKE_OSX_ARCHITECTURES=x86_64 \
-DCMAKE_OSX_DEPLOYMENT_TARGET=10.7 \
-DCMAKE_OSX_SYSROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk \
-DUSE_ALLEG4_BACKEND=OFF \
-DUSE_SKIA_BACKEND=ON \
-DSKIA_DIR=$HOME/deps/skia \
-DWITH_HarfBuzz=OFF \
-G Ninja \
..
ninja aseprite
In this case, `$HOME/deps/skia` is the directory where Skia was
compiled as described in [Skia on macOS](#skia-on-macos) section.
### Issues with Retina displays
If you have a Retina display, check the following issue:
https://github.com/aseprite/aseprite/issues/589
## Linux details
On Linux you can specify a specific directory to install Aseprite
after a `ninja install` command. For example:
cd aseprite
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=~/software -G Ninja ..
ninja aseprite
Then, you can invoke `ninja install` and it will copy the program in
the given location (e.g. `~/software/bin/aseprite` on Linux).
# Using shared third party libraries
If you don't want to use the embedded code of third party libraries
(i.e. to use your installed versions), you can disable static linking
configuring each `USE_SHARED_` option.
After running `cmake -G`, you can edit `build/CMakeCache.txt` file,
and enable the `USE_SHARED_` flag (set its value to `ON`) of the
library that you want to be linked dynamically.
## Linux issues
If you use the official version of Allegro 4.4 library (i.e. you
compile with `USE_SHARED_ALLEGRO4=ON`) you will experience a couple of
known issues solved in
[our patched version of Allegro 4.4 library](https://github.com/aseprite/aseprite/tree/master/src/allegro):
* You will
[not be able to resize the window](https://github.com/aseprite/aseprite/issues/192)
([patch](https://github.com/aseprite/aseprite/commit/920f6275d55113507121afcbcda80adb44cc0563)).
* You will have problems
[adding HSV colors in non-English systems](https://github.com/aseprite/aseprite/commit/27b55030e26e93c5e8d9e7e21206c8709d46ff22)

# Building Skia dependency
When you compile Aseprite with [Skia](https://skia.org) as back-end on
Windows or macOS, you need to compile a specific version of Skia. In
the following sections you will find straightforward steps to compile
Skia.
You can always check the
[official Skia instructions](https://skia.org/user/quick) and select
the OS you are building for. Aseprite uses the `aseprite-m55` Skia
branch from `https://github.com/aseprite/skia`.
## Skia on Windows
Download
[Google depot tools](https://storage.googleapis.com/chrome-infra/depot_tools.zip)
and uncompress it in some place like `C:\deps\depot_tools`.
Then open a command line follow these steps (for VS2015):
call "%VS140COMNTOOLS%\vsvars32.bat"
set PATH=C:\deps\depot_tools;%PATH%
cd C:\deps\depot_tools
gclient sync
(The `gclient` command might print an error like
`Error: client not configured; see 'gclient config'`.
Just ignore it.)
cd C:\deps
git clone https://github.com/aseprite/skia.git
cd skia
git checkout aseprite-m55
python bin/sync-and-gyp
(The `bin/sync-and-gyp` will take some minutes because it downloads a
lot of packages, please wait and re-run the same command in case it fails.)
ninja -C out/Release dm
More information about these steps in the
[official Skia documentation](https://skia.org/user/quick/windows).
## Skia on macOS
These steps will create a `deps` folder in your home directory with a
couple of subdirectories needed to build Skia (you can change the
`$HOME/deps` with other directory). Some of these commands will take
several minutes to finish:
mkdir $HOME/deps
cd $HOME/deps
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
git clone https://github.com/aseprite/skia.git
export PATH="${PWD}/depot_tools:${PATH}"
cd skia
git checkout aseprite-m55
python bin/sync-and-gyp
ninja -C out/Release dm
After this you should have all Skia libraries compiled. When you
[compile Aseprite](#compiling), remember to add
`-DSKIA_DIR=$HOME/deps/skia` parameter to your `cmake` call as
described in the [macOS details](#macos-details) section.
More information about these steps in the
[official Skia documentation](https://skia.org/user/quick/macos).
