<h2>The main configuration BuildFile</h2> |
| 20 |
|
The file <em>config/BuildFile</em> is resourced by all others in the entire |
| 21 |
|
tree. It controls everything else. The most important thing to set here is the |
| 22 |
< |
<ClassPath> tags which associate <a href=#Structural>Structure BuildFiles</a> |

with directory structure and set up the directory structures for the |
| 24 |

BuildSystem. You may also want to set project wide defaults. |

<h3>Defining Project Structure</h3> |
| 27 |
|
You need to tell SCRAM where it can store such things as libraries, binaries |
| 32 |
|
<font color=green> |
| 33 |
|
<ProductStore name=lib type=arch><br> |
| 34 |
|
<ProductStore name=bin type=arch><br> |
| 35 |
+ |
<ProductStore name=module type=arch><br> |
| 36 |
|
</font> |
| 37 |
< |
<em>Note: Currently, bin and lib are hard-coded so you cannot point them elsewhere |
| 37 |
< |
without something breaking</em> |
| 37 |
> |
|
| 38 |
|
<h3>Using the <a href=BuildFile/tag_ClassPath.html><ClassPath></a> tag</h3> |
| 39 |
|
This tag tells SCRAM which BuildFile to associate with a particular location in |
| 40 |
|
the src tree.<p> |
| 49 |
|
</pre> |
| 50 |
|
</font> |
| 51 |
|
This will associate the top level src directory with the BuildFile |
| 52 |
< |
<em>config/TopLevel_BuildFile</em> (or config/TopLevel_makefile.mk). Any |
| 53 |
< |
directory in the next level below with <em>config/SubSystem_BuildFile</em> |
| 54 |
< |
, the level below that with <em>config/Package_BuildFile</em>. |
| 55 |
< |
The last element in the path has a pattern matching string before the +, thus |
| 52 |
> |
<em>config/TopLevel_BuildFile</em> (and the corresponding makefile |
| 53 |
> |
config/TopLevel_makefile.mk), any directory in the next level |
| 54 |
> |
with <em>config/SubSystem_BuildFile</em> |
| 55 |
> |
and the level below that with <em>config/Package_BuildFile</em>. |
| 56 |
> |
|
| 57 |
> |
|
| 58 |
> |
The last element in the path has a pattern matching string before the "+" sign, so |
| 59 |
|
only directories called <em>src</em> at the 3rd level below the top level |
| 60 |
< |
will be mapped to <em>config/library_BuildFile</em>. |
| 60 |
> |
will be mapped to <em>config/library_BuildFile</em>. |
| 61 |
|
The second tag in the BuildFile has the same structure except it maps |
| 62 |
< |
directories called <em>test</em> at this level to |
| 63 |
< |
<em>config/UnitTest_BuildFile</em>. |
| 61 |
< |
Any that do not match a ClassPath will be |
| 62 |
< |
mapped to DEFAULT_BuildFile (which must exist). |

directories called <em>test</em> at this level to <em>config/UnitTest_BuildFile</em>. |

Any that do not match a ClassPath will be mapped to DEFAULT_BuildFile (which must exist). |
| 64 |

| 65 |
|
<p> |
| 66 |
|
In a case where multiple <ClassPath> tags are defined it is always the last |
| 67 |
|
one that matches the stated path that is taken. |

|
<h2>Structure BuildFiles</h2> |
| 70 |
|
These are the BuildFles that the <ClassPath> tags described above refer to. |
| 71 |
|
They must exist in the project configuration directory. Their purpose is |
| 72 |
|
to define default build behaviour and default settings that is to be associated |
| 73 |
< |
with a location. The <Build> tag can be used here to specify build products |
| 74 |
< |
Note that anything outside of tags is standard gmake. |

Note that anything outside a tag is standard makefile syntax and will be parsed directly |

by gmake. |
