# Build Instructions (Linux)
|
|
|
|
Follow the guidelines below for building Electron on Linux.
|
|
|
|
## Prerequisites
|
|
|
|
* Python 2.7.x. Some distributions like CentOS still use Python 2.6.x
|
|
so you may need to check your Python version with `python -V`.
|
|
* Node.js v0.12.x. There are various ways to install Node. You can download
|
|
source code from [Node.js](http://nodejs.org) and compile from source.
|
|
Doing so permits installing Node on your own home directory as a standard user.
|
|
Or try repositories such as [NodeSource](https://nodesource.com/blog/nodejs-v012-iojs-and-the-nodesource-linux-repositories).
|
|
* Clang 3.4 or later.
|
|
* Development headers of GTK+ and libnotify.
|
|
|
|
On Ubuntu, install the following libraries:
|
|
|
|
```bash
|
|
$ sudo apt-get install build-essential clang libdbus-1-dev libgtk2.0-dev \
|
|
libnotify-dev libgnome-keyring-dev libgconf2-dev \
|
|
libasound2-dev libcap-dev libcups2-dev libxtst-dev \
|
|
libxss1 libnss3-dev gcc-multilib g++-multilib curl
|
|
```
|
|
|
|
On Fedora, install the following libraries:
|
|
|
|
```bash
|
|
$ sudo yum install clang dbus-devel gtk2-devel libnotify-devel libgnome-keyring-devel \
|
|
xorg-x11-server-utils libcap-devel cups-devel libXtst-devel \
|
|
alsa-lib-devel libXrandr-devel GConf2-devel nss-devel
|
|
```
|
|
|
|
Other distributions may offer similar packages for installation via package
|
|
managers such as pacman. Or one can compile from source code.
|
|
|
|
## If You Use Virtual Machines For Building
|
|
|
|
If you plan to build Electron on a virtual machine you will need a fixed-size
|
|
device container of at least 25 gigabytes in size.
|
|
|
|
## Getting the Code
|
|
|
|
```bash
|
|
$ git clone https://github.com/electron/electron.git
|
|
```
|
|
|
|
## Bootstrapping
|
|
|
|
The bootstrap script will download all necessary build dependencies and create
|
|
the build project files. You must have Python 2.7.x for the script to succeed.
|
|
Downloading certain files can take a long time. Notice that we are using
|
|
`ninja` to build Electron so there is no `Makefile` generated.
|
|
|
|
```bash
|
|
$ cd electron
|
|
$ ./script/bootstrap.py -v
|
|
```
|
|
|
|
### Cross compilation
|
|
|
|
If you want to build for an `arm` target you should also install the following
|
|
dependencies:
|
|
|
|
```bash
|
|
$ sudo apt-get install libc6-dev-armhf-cross linux-libc-dev-armhf-cross \
|
|
g++-arm-linux-gnueabihf
|
|
```
|
|
|
|
And to cross compile for `arm` or `ia32` targets, you should pass the
|
|
`--target_arch` parameter to the `bootstrap.py` script:
|
|
|
|
```bash
|
|
$ ./script/bootstrap.py -v --target_arch=arm
|
|
```
|
|
|
|
## Building
|
|
|
|
If you would like to build both `Release` and `Debug` targets:
|
|
|
|
```bash
|
|
$ ./script/build.py
|
|
```
|
|
|
|
This script will cause a very large Electron executable to be placed in
|
|
the directory `out/R`. The file size is in excess of 1.3 gigabytes. This
|
|
happens because the Release target binary contains debugging symbols.
|
|
To reduce the file size, run the `create-dist.py` script:
|
|
|
|
```bash
|
|
$ ./script/create-dist.py
|
|
```
|
|
|
|
This will put a working distribution with much smaller file sizes in
|
|
the `dist` directory. After running the create-dist.py script, you
|
|
may want to remove the 1.3+ gigabyte binary which is still in `out/R`.
|
|
|
|
You can also build the `Debug` target only:
|
|
|
|
```bash
|
|
$ ./script/build.py -c D
|
|
```
|
|
|
|
After building is done, you can find the `electron` debug binary under `out/D`.
|
|
|
|
## Cleaning
|
|
|
|
To clean the build files:
|
|
|
|
```bash
|
|
$ ./script/clean.py
|
|
```
|
|
|
|
## Troubleshooting
|
|
|
|
Make sure you have installed all of the build dependencies.
|
|
|
|
### Error While Loading Shared Libraries: libtinfo.so.5
|
|
|
|
Prebulit `clang` will try to link to `libtinfo.so.5`. Depending on the host
|
|
architecture, symlink to appropriate `libncurses`:
|
|
|
|
```bash
|
|
$ sudo ln -s /usr/lib/libncurses.so.5 /usr/lib/libtinfo.so.5
|
|
```
|
|
|
|
## Tests
|
|
|
|
Test your changes conform to the project coding style using:
|
|
|
|
```bash
|
|
$ ./script/cpplint.py
|
|
```
|
|
|
|
Test functionality using:
|
|
|
|
```bash
|
|
$ ./script/test.py
|
|
```
