# Build instructions (Linux)
## Prerequisites
* [Node.js](http://nodejs.org)
* Clang 3.4 or later
* Development headers of GTK+ and libnotify
On Ubuntu you could install the libraries via:
```bash
$ sudo apt-get install build-essential clang libdbus-1-dev libgtk2.0-dev libnotify-dev libgnome-keyring-dev libgconf2-dev gcc-multilib g++-multilib
```
Latest Node.js could be installed via ppa:
```bash
$ sudo apt-get install python-software-properties software-properties-common
$ sudo add-apt-repository ppa:chris-lea/node.js
$ sudo apt-get update
$ sudo apt-get install nodejs
# Update to latest npm
$ sudo npm install npm -g
```
## Getting the code
```bash
$ git clone https://github.com/atom/atom-shell.git
```
## Bootstrapping
The bootstrap script will download all necessary build dependencies and create
build project files. Notice that we're using `ninja` to build `atom-shell` so
there is no `Makefile` generated.
```bash
$ cd atom-shell
$ ./script/bootstrap.py
```
## Building
Build both `Release` and `Debug` targets:
```bash
$ ./script/build.py
```
You can also only build the `Debug` target:
```bash
$ ./script/build.py -c Debug
```
After building is done, you can find `atom` under `out/Debug`.
## Troubleshooting
### fatal error: bits/predefs.h: No such file or directory
If you got an error like this:
````
In file included from /usr/include/stdio.h:28:0,
from ../../../svnsrc/libgcc/../gcc/tsystem.h:88,
from ../../../svnsrc/libgcc/libgcc2.c:29:
/usr/include/features.h:324:26: fatal error: bits/predefs.h: No such file or directory
#include <bits/predefs.h>
````
Then you need to install `gcc-multilib` and `g++-multilib`, on Ubuntu you can do
this:
```bash
$ sudo apt-get install gcc-multilib g++-multilib
```
### error adding symbols: DSO missing from command line
If you got an error like this:
````
/usr/bin/ld: vendor/download/libchromiumcontent/Release/libchromiumcontent.so: undefined reference to symbol 'gconf_client_get'
//usr/lib/x86_64-linux-gnu/libgconf-2.so.4: error adding symbols: DSO missing from command line
````
libchromiumcontent.so is build with clang 3.0 which is incompatible with newer
versions of clang. Try using clang 3.0, default version in Ubuntu 12.04.
## Tests
```bash
$ ./script/test.py
```
