There are a number of targets available to help you specify exactly what you |
| 59 |
+ |
wish to build. <br> |
| 60 |
+ |
If no target is specified a default action is performed |
| 61 |
+ |
which is defined according to the policy of the given project. |
| 62 |
+ |
<p> |
| 63 |

<b>scram build <em>target_name</em></b> |

<h1>Constructing a BuildFile to describe a binary</h1> |
| 72 |
+ |
<ol> |
| 73 |
+ |
<li><h2>The <bin> tag</h2> |
| 74 |
+ |
Syntax |
| 75 |
+ |
<pre> |
| 76 |
+ |
<bin file=<em>filename</em> [name=alternativename]> |
| 77 |
+ |
You can add some descriptive documentation for your executable here - how about a href? |
| 78 |
+ |
</bin> |
| 79 |
+ |
</pre> |
| 80 |
+ |
Every executable to be made must have a corresponding bin tag in the BuildFile. <p> |
| 81 |
+ |
The optional <b>name=</b> |
| 82 |
+ |
argument allows you to change the name from the default (which is the filename |
| 83 |
+ |
less the subscript) |
| 84 |
+ |
<p> |
| 85 |
+ |
<li><a name=Dep><h2>Specifying Dependencies</h2></a> |
| 86 |
+ |
A binary can depend on many other elements. Currently scram supports the concepts and associated |
| 87 |
+ |
tags as given in the table below : |
| 88 |
+ |
<table> |
| 89 |
+ |
<tr> |
| 90 |
+ |
<td><font color=green> |
| 91 |
+ |
<external ref=<em>external_product_ref</em>></font></td> |
| 92 |
+ |
<td> |
| 93 |
+ |
Specify that the build requires some external product |
| 94 |
+ |
(e.g. libraries, header files etc.). Currently the only supported ref is |
| 95 |
+ |
a simple name label set at the project level. Such names are part of the project configuration. |
| 96 |
+ |
</td> |
| 97 |
+ |
</tr> |
| 98 |
+ |
<tr> |
| 99 |
+ |
<td><font color=green> |
| 100 |
+ |
<lib name=<em>libname</em>></font></td> |
| 101 |
+ |
<td>Add a library name to the link line. It is assumed that the libraries can be found in the |
| 102 |
+ |
standard scram search paths</td> |
| 103 |
+ |
</tr> |
| 104 |
+ |
<tr> |
| 105 |
+ |
<td><font color=green> |
| 106 |
+ |
<Use name=<em>unit_name</em>></font></td> |
| 107 |
+ |
<td>Inform build system that we require package <em>unit_name</em> in |
| 108 |
+ |
the build. A package is a unit within the current source code and requires that an appropriate |
| 109 |
+ |
interface has been defined in the appropriate BuildFile with the |
| 110 |
+ |
<a href=export.html><export> tags</a> |
| 111 |
+ |
</td> |
| 112 |
+ |
</tr> |
| 113 |
+ |
<tr> |
| 114 |
+ |
<td><font color=green> |
| 115 |
+ |
<Group name=<em>group_name</em>></font></td> |
| 116 |
+ |
<td>Inform build system to set a specific group. |
| 117 |
+ |
Groups are either containers of other groups (defined at the project configuration level) |
| 118 |
+ |
, or can be used to switch in/out functionality |
| 119 |
+ |
from an <a href=export.html><export> interface</a> |
| 120 |
+ |
</td> |
| 121 |
+ |
</table> |
| 122 |
+ |
Each of these tags can be put in the BuildFile to build up an 'Environment' in which the |
| 123 |
+ |
binary is to be built. The BuildFile itself provides the base environment, however more control |
| 124 |
+ |
can be achieved using the <Environment> </Environment> tags, to determine its extent. |
| 125 |
+ |
Any <bin> tag inside the <Environment> delimiters will be associated with that (and any other enclosing) environment. |
| 126 |
+ |
Note that since the BuildFile is an Environment in itself - it encloses all other Environments and as such any dependency specified outside of an <Environment> tag will apply to all binaries. |
