<li><h2>Development Spaces</h2>
|

<h3>What are Development Spaces?</h3>
|
| 40 |
A development space is an isolated area that you can use to work on a
|
| 41 |
given project without affecting anyone else. This development space is
|
| 42 |
associated with a specific installation of the project from which it can
|
| 43 |
draw resources (e.g libraries, include files, environment) as required.
|
| 44 |
<h3>Creating Your Local Development Space</h3>
|
| 45 |
To develop on a given project you first need to have a copy of the project
|
| 46 |
installed at your site on which to base your development area.
|
| 47 |
You can see the available locally installed copies
|
| 48 |
with the command :<p>
|
| 49 |
<font size=-1><b>scram list</b></font>
|
| 50 |
<p>
|
| 51 |
To create your personal space you then issue the command:
|
| 52 |
<p>
|
| 53 |
<font size=-1><b>
|
| 54 |
scram project <em>project_name</em> <em>project_version</em>
|
| 55 |
</b>
|
| 56 |
</font>
|
| 57 |
<p>
|
| 58 |
Where <em>project_name</em> and <em>project_version</em> correspond to those
|
| 59 |
available from the <font size=-1><b>scram list</b></font> command.
|
| 60 |
<p>
|
| 61 |
The development area will reflect the structure and will have the same
|
| 62 |
build environment as the base project specified.
|
| 63 |
<p>
|
| 64 |
<li><h2>Using The Development Area</h2>
|
| 65 |
Assuming you are at the top of your new development area:
|
| 66 |
<table border=0>
|
| 67 |
<tr>
|
| 68 |
<td>
|
| 69 |
<font size=-1>
|
| 70 |
<b>cd src</font></b></td><td> goto the src directory</td></tr>
|
| 71 |
<tr>
|
| 72 |
<td valign=top><font size=-1>
|
| 73 |
<b>cvs co <em>module</em></b> (e.g. for cvs based projects)</font></td>
|
| 74 |
<td>Check out whatever module you require. As an example, you may wish to
|
| 75 |
develop a module that corresponds to a library. You will need to check-out the
|
| 76 |
entire module, rather than just the files your working on, as the library
|
| 77 |
building system uses the local file list to specify the library contents.
|
| 78 |
<p>
|
| 79 |
Once checked out you can cd into the module and edit the files as
|
| 80 |
required.
|
| 81 |
<p><em><b>Note</b> The cvs co command above will give you the development head.
|
| 82 |
If you wish to use a fixed tagged version or the head of a different
|
| 83 |
development branch you must specify this with the -r option to cvs.
|
| 84 |
<p>
|
| 85 |
e.g. <font size=-1><b>cvs co -r beta <em>module</em></b>
|
| 86 |
</font>
|
| 87 |
<p>
|
| 88 |
</td>
|
| 89 |
</tr>
|
| 90 |
<td valign=top><font size=-1>
|
| 91 |
<b>
|
| 92 |
scram build</b></td>
|
| 93 |
</font>
|
| 94 |
<td>Will perform the default build that corresponds to the directory in which
|
| 95 |
you type the command.</td>
