# build-essential Cookbook
[![Cookbook Version](http://img.shields.io/cookbook/v/build-essential.svg)][cookbook] [![Build Status](http://img.shields.io/travis/chef-cookbooks/build-essential.svg)][travis]
Installs packages required for compiling C software from source. Use this cookbook if you wish to compile C programs, or install RubyGems with native extensions.
## Requirements
### Platforms
- Debian/Ubuntu
- RHEL/CentOS/Scientific/Amazon/Oracle
- openSUSE
- SmartOS
- Fedora
- Mac OS X
- FreeBSD
### Chef
- Chef 11+
### Cookbooks
- Suggests pkgutil for Solaris based platforms
**Note for Debian platform family:** On Debian platform-family systems, it is recommended that `apt-get update` be run, to ensure that the package cache is updated. It's not in the scope of this cookbook to do that, as it can [create a duplicate resource](https://tickets.chef.io/browse/CHEF-3694). We recommend using the [apt](https://supermarket.chef.io/cookbooks/apt) cookbook to do this.
**Note for OmniOS**: Currently, OmniOS's Ruby package is built with GCC 4.6.3, and the path is hardcoded, as the gcc binaries are not installed in the default $PATH. This means that in order to install RubyGems into the "system" Ruby, one must install `developer/gcc46`. [An issue](https://github.com/omniti-labs/omnios-build/issues/19) is open upstream w/ OmniOS to rebuild the Ruby package with GCC 4.7.2.
## Attributes
Attribute | Default | Description
----------------------------------------- | :--------------------------: | ---------------------------------
`node['build-essential']['compile_time']` | `false` | Execute resources at compile time
`node['build-essential']['msys']['path']` | `#{ENV['SYSTEMDRIVE']\\msys` | Destination for msys (Windows only)
## Usage
Include the build-essential recipe in your run list:
```sh
knife node run_list add NODE "recipe[build-essential::default]"
```
or add the build-essential recipe as a dependency and include it from inside another cookbook:
```ruby
include_recipe 'build-essential::default'
```
### Gems with C extensions
For RubyGems that include native C extensions you wish to use with Chef, you should do the following.
- Set the `compile_time` attribute to true in your wrapper cookbook or role:
```ruby
# Wrapper attribute
default['build-essential']['compile_time'] = true
```
```ruby
# Role
default_attributes(
'build-essential' => {
'compile_time' => true
}
)
```
- Ensure that the C libraries, which include files and other assorted "dev"
type packages, are installed in the compile phase after the build-essential
recipe is executed. For example:
```ruby
include_recipe 'build-essential::default'
package('mypackage-devel') { action :nothing }.run_action(:install)
```
- Use the `chef_gem` resource in your recipe to install the gem with the native
extension:
```ruby
chef_gem 'gem-with-native-extension'
```
