Method: Inventory::Rake::Tasks::Compile#define

Defined in:
lib/inventory-rake-1.0/tasks/compile.rb

#define ⇒ Object

Defines the following task:

<dl>

<dt>compile</dt>
<dd>Compile all extensions; depends on each compile:<em>name</em>.</dd>

</dl>

Then, for each extension in the inventory, define the following tasks:

<dl>

<dt>compile:<em>name</em></dt>
<dd>Compile extension <em>name</em>; depends on
lib/<em>path</em>/<em>so</em> file.</dd>

<dt>lib/<em>path</em>/<em>so</em></dt>
<dd>Installed dynamic library of extension <em>name</em> inside inventory
path; depends on ext/<em>name</em>/<em>so</em>.</dd>

<dt>ext/<em>name</em>/<em>so</em></dt>
<dd>Dynamic library of extension <em>name</em>; depends on
ext/<em>name</em>/Makefile and the source files of the extension.</dd>

<dt>ext/<em>name</em>/Makefile</dt>
<dd>Makefile for extension <em>name</em>; depends on inventory path,
ext/<em>name</em>/extconf.rb file, and ext/<em>name</em>/depend file.
Will be created by extconf.rb, which may take options from environment
variable <em>name#upcase</em><code>_EXTCONF_OPTIONS</code> or
<code>EXTCONF_OPTIONS</code> if defined.</dd>

<dt>clean:<em>name</em></dt>
<dd>Clean files built for extension <em>name</em>; depended upon by
clean.</dd>

</dl>

Finally, if defined, the test task is set to depend on the compile task.
