3.4 Using External Libraries
|
| 70 |
</H1>
|
| 71 |
A dependency on an external product is satisfied using the statement
|
| 72 |
|
| 73 |
<P>
|
| 74 |
|
| 75 |
<UL>
|
| 76 |
<<TT>external</TT> ref=<I>name</I> [use=<I>subsystem</I>]>
|
| 77 |
</LI>
|
| 78 |
</UL><A NAME="1863"></A>
|
| 79 |
in a <TT>BuildFile</TT>. The option <TT>use=</TT>...can be
|
| 80 |
specified where the <<TT>export</TT>> interface has been defined
|
| 81 |
in another <SMALL>SCRAM</SMALL>-managed project, i.e. it allows you to choose
|
| 82 |
subsets of libraries from another project in the same way as if you
|
| 83 |
had used <<TT>use</TT> name=...> tag in you local project. Note
|
| 84 |
that if the used interface itself declares an external using the
|
| 85 |
<<TT>external</TT>> tag then the tool referred to must exist in
|
| 86 |
the local project tool configuration (and be visible in the list of
|
| 87 |
tools shown by <TT>scram tool list</TT>).
|
| 88 |
|
| 89 |
<P>
|
| 90 |
Here are two examples of how the tag might be used.
