| 39 | <p>It is desirable to declare standard libraries available on a |
|---|
| 40 | given system. Putting target declaration in Jamfile is not really |
|---|
| 41 | good, since locations of the libraries can vary. The solution is |
|---|
| 42 | to put the following to site-config.jam.</p> |
|---|
| 43 | <pre class="programlisting"> |
|---|
| 44 | import project ; |
|---|
| 45 | project.initialize $(__name__) ; |
|---|
| 46 | project site-config ; |
|---|
| 47 | lib zlib : : <name>z ; |
|---|
| 48 | </pre> |
|---|
| 49 | <p>The second line allows this module to act as project. The |
|---|
| 50 | third line gives id to this project — it really has no location |
|---|
| 51 | and cannot be used otherwise. The fourth line just declares a |
|---|
| 52 | target. Now, one can write: |
|---|
| 53 | </p> |
|---|
| 54 | <pre class="programlisting"> |
|---|
| 55 | exe hello : hello.cpp /site-config//zlib ; |
|---|
| 56 | </pre> |
