<h2>Online help</h2>
|
| 10 |
Apart from these web pages, help is available through the use of the help
|
| 11 |
command.
|
| 12 |
<p>e.g.<br>
|
| 13 |
<font size=-1>
|
| 14 |
scram help</font> will list the available scram commands
|
| 15 |
<br>
|
| 16 |
<font size=-1>
|
| 17 |
scram build help </font> List available build targets<br>
|
| 18 |

|
| 19 |
<font size=-1>

<h2>Creating your local development space</h2>
|
| 22 |
This section assumes that you have a locally installed copy of the project
|
| 23 |
you wish to work on. ( You can see the available locally installed copies
|
| 24 |
with the <font size=-1>scram list</font> command).
|
| 25 |
<p>
|
| 26 |
<font size=-1>
|
| 27 |
scram project <em>project_name</em> <em>project_version</em>
|
| 28 |
</font>
|
| 29 |
This command will create a development area. The development area will
|
| 30 |
reflect the structure and will have the same
|
| 31 |
build environment as the base project specified.
|
| 32 |
<h2>Using The Development Area</h2>
|
| 33 |
Assuming you are at the top of your new development area:
|
| 34 |
<table border=0>
|
| 35 |
<tr>
|
| 36 |
<td>
|
| 37 |
<font size=-1>
|
| 38 |
cd src</font></td><td> goto the src directory</td></tr>
|
| 39 |
<tr>
|
| 40 |
<td><font size=-1>
|
| 41 |
cvs co <em>module</em> (e.g. for cvs based projects)</font></td>
|
| 42 |
<td>Check out whatever module you require. As an example, you may wish to
|
| 43 |
develop a module that corresponds to a library. You will need to check-out the
|
| 44 |
entire module, rather than just the files your working on, as the library
|
| 45 |
building system uses the local file list to specify the library contents.
|
| 46 |
<p>
|
| 47 |
Once checked out you can cd into the module and edit the files as
|
| 48 |
required.
|
| 49 |
<p><em><b>Note</b> The cvs co command above will give you the development head.
|
| 50 |
If you wish to use a fixed tagged version or the head of a different
|
| 51 |
development branch you must specify this with the -r option to cvs.
|
| 52 |
<p>
|
| 53 |
e.g. <font size=-1>cvs co -r beta <em>module</em>
|
| 54 |
</font>
|
| 55 |
<p>

<td>Will perform the default build that corresponds to the directory in which
|
| 62 |
you type the command.</td>
