[](https://travis-ci.org/mapbox/mapbox-gl-native/builds)
An OpenGL renderer for [Mapbox Vector Tiles](https://www.mapbox.com/blog/vector-tiles),
implemented in C++11, currently targeting iOS, OS X, and Ubuntu Linux.
# Depends
- Modern C++ compiler that supports `-std=c++11` (On OS X clang++, on Linux g++-4.8 or g++-4.9)
- [Boost headers](http://boost.org/)
- [`zlib`](http://www.zlib.net/)
- [`libpng`](http://www.libpng.org/pub/png/libpng.html)
- [`libuv 0.10+`](https://github.com/joyent/libuv)
- [`glfw 3.1+`](http://www.glfw.org/)
- [`libcurl`](http://curl.haxx.se/libcurl/) (depends on OpenSSL; Linux only)
- Apple Command Line Tools (for build on OS X; available at [Apple Developer](https://developer.apple.com/downloads))
- `pkg-config` (for build only)
- [Homebrew](http://brew.sh) (for build on OS X)
- Python 2.x (for build only)
# Build instructions
We try to link to as many system-provided libraries as possible. When these are unavailable or too outdated, we run a thin build-script layer called [Mason](https://github.com/mapbox/mason) to automate builds, and load precompiled binary packages when possible.
## OS X
On OS X, we are using `zlib`, `SQLite3`, `libcurl` and `libpng` provided by the operating system. In addition to that, you need to have the Boost headers installed. To install all prerequisites, use [Homebrew](http://brew.sh/) and type `brew install pkg-config boost`.
To create projects, you can run:
- `make xproj`: Creates an Xcode project with OS X-specific handlers for HTTP downloads and settings storage. It uses [GLFW](http://www.glfw.org) for window handling.
- `make lproj`: Creates an Xcode project with platform-independent handlers for downloads and settings storage. This is what is also being built on Linux.
- `make osx run-osx`: Builds and runs the OS X application on the command line with `xcodebuild`.
- `make linux run-linux`: Builds and runs the Linux application with `make`.
Note that you can't have more than one project in Xcode open at a time since they the static library project is shared across the OS X, Linux and iOS project.
Target OS: 10.9+
## iOS
iOS makes use of a Cocoa-specific API called [`mapbox-gl-cocoa`](https://github.com/mapbox/mapbox-gl-cocoa). If you are just interested in running Mapbox GL on iOS and not developing with it, head to that project and you can use this library as a pre-built static library instead. A `UIView` interface to the map view and bundle resources are provided there.
If you intend to develop here, `mapbox-gl-cocoa` is included as a submodule of the overall build setup.
To pull down the submodule(s), run:
git submodule init
git submodule update
Then, you can run `make iproj` to create and open an Xcode project with an iOS-specific view controller housing. This will automatically install required dependencies as well.
Note that if you are doing OS X development as well, to toggle from OS X back to iOS, you will need to `make iproj` again.
Target devices: iPhone 4S and above (5, 5c, 5s, 6, 6 Plus) and iPad 2 and above (3, 4, Mini , Air, Mini 2, Air 2).
Target OS: 7.0+
## Linux
We are using Ubuntu for development. While the software should work on other distributions as well, we are not providing explicit build instructions here.
Install GCC 4.8+ if you are running Ubuntu 13.10 or older. Alternatively, you can also use Clang 3.4+.
sudo add-apt-repository --yes ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.8 g++-4.8
Ensure you have git and other build essentials:
sudo apt-get install curl git build-essential zlib1g-dev automake \
libtool xutils-dev make cmake pkg-config python-pip \
libcurl4-openssl-dev libpng-dev libsqlite3-dev
Install glfw3 dependencies:
sudo apt-get install libxi-dev libglu1-mesa-dev x11proto-randr-dev \
x11proto-xext-dev libxrandr-dev \
x11proto-xf86vidmode-dev libxxf86vm-dev \
libxcursor-dev libxinerama-dev
Finally, install Boost. If you're running Ubuntu 12.04 or older, you need to install a backport PPA since the version provided by APT doesn't contain Boost Geometry:
sudo add-apt-repository --yes ppa:boost-latest/ppa
sudo apt-get update
sudo apt-get install libboost1.55-dev
Otherwise, you can just install
sudo apt-get install libboost-dev
Once you're done installing the build dependencies, you can get started by running
./configure
which downloads all other dependencies that we need to build manually with [Mason](https://github.com/mapbox/mason). There's a good chance that there already are binary files and that you don't need to compile anything.
Then, you can then proceed to build the library like:
make mbgl
Or proceed to building the debug application with:
make linux
Be sure to setup an access token per below before running `build/Release/mapbox-gl`.
# Troubleshooting
To trigger a complete rebuild, run `make clean` and then start over generating the Xcode projects or Makefiles as described above.
If you are having trouble getting the dependencies right, you can blow away the `mason_packages` directory, or run `make distclean`. This means the Makefile and configure script will automatically install the dependencies again on the next try.
On OS X, you can also try clearing the Xcode cache with `make clear_xcode_cache`.
# Mapbox API access tokens
The demo applications use Mapbox vector tiles, which **require a Mapbox account and API access token**. Obtain an access token on the [Mapbox account page](https://www.mapbox.com/account/apps/).
For iOS and OS X use of the demo apps in Xcode, setup the access token by editing the scheme for the application target, then adding an environment variable with the name `MAPBOX_ACCESS_TOKEN`.
For Linux, set the environment variable `MAPBOX_ACCESS_TOKEN` to your token.
# Style
Some styles in JSON format are included at `./styles`. See the [style spec](https://github.com/mapbox/mapbox-gl-style-spec) for more details.
# Usage
## Desktop
- Press `X` to reset the transform
- Press `N` to reset north
- Press `Tab` to toggle debug information
- Press `Esc` to quit
## Mobile
- Pan to move
- Pinch to zoom
- Use two fingers to rotate
- Double-tap to zoom in one level
- Two-finger single-tap to zoom out one level
- Single-tap to toggle the command palette visibility for resetting north & the transform, toggling debug, and locating the user
- Double-tap, long-pressing the second, then pan up and down to "quick zoom" (iPhone only, meant for one-handed use)
# Other notes
Under early development, this project was called LLMR (Low-Level Map Renderer), in case you see any lingering references to it.
