The Default Build is configured at the project level. The default can be
|
| 4 |
|
|
overridden or parameters passed to the default build rules through the
|
| 5 |
|
|
BuildFile.

<li>The Binary Executable<p>
|
| 12 |
|
|
The binary building rules require explicit specification of the binary targets
|
| 13 |
|
|
e.g.
|

|
|

<bin file=example1.cpp>

You can write between bin tags some documentation to describe what the binary
|
| 23 |
|
|
does
|
| 24 |
williamc |

</bin>
|
| 25 |
|
|
<bin file=example2.cpp name=mytestexe>
|
| 26 |
williamc |

Here we call the final binary a different name from the default.

This file will build two executables called (example1 and mytestexe) from files example1.cpp and example2.cpp respectively. Both are built in the context of
|
| 34 |
|
|
external libraries cmsim and X11 as well as a local package from the same
|
| 35 |
williamc |
1.2 |
project called CARF <p>

<em><b>Note: Theres still much work to be done here</b></em><br>

<li> </External> and </Use> tags do not remove the
|
| 39 |
williamc |
1.2 |
external package as you might expect.
|
| 40 |
|
|
<li> Anything Outside of the bin tags will be included in the
|
| 41 |
|
|
GNUmakefile. This allows you the full functionality of gmake
|
| 42 |
|
|
to make up for any inadequacies. Hopefully as full scram
|
| 43 |
|
|
binary functionality is achieved this will be phased out

You may wish to exclude some files from a
|
| 48 |
williamc |
1.1 |
build or include external package headers or assign the module to a group.
|
| 49 |
|
|
<br>e.g.<p>
|

williamc |
1.4 |
<font color=green>

It is also possible to override the default type of library that is built
|
| 59 |
|
|
<br>e.g.<p>

|

<font color=green>
|
| 61 |

|

|

<h2>Avoiding Processing Parts of BuildFiles</h2>
|
| 80 |
|
|
Anything between <ignore> and </ignore> tags will be excluded
|
| 81 |
|
|
from processing during the build. This is a convenient mechanism to cut
|
| 82 |
|
|
out sections of the BuildFile and is not intended for comments. Comments
|
| 83 |
|
|
should be provided where apppropriate e.g. in between <binb> and </bin>
|
| 84 |
|
|
tags.
