- Boost Test Library components provide several usage variants: to create a test
- program you can link with the one of the precompiled library variants or use
- header-only variant. For example, to use Unit Test Framework you may either
- include
- </p>
- <pre class="programlisting"><span class="preprocessor">#include</span> <span class="special"><</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">test</span><span class="special">/</span><span class="identifier">unit_test</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">></span>

- </p>
- <pre class="programlisting"><span class="identifier">libunit_test_framework</span><span class="special">.</span><span class="identifier">lib</span></pre>

- </pre>
- <p>
- in which case you should not need to link with any pre-compiled component.
- Note also that you should strictly follow specification on initialization function
- in other case some compilers may produce linker error like this.

- <p>
