| 13 |   <para>In the final-system build, you are no longer cross-compiling so it
 | 
|---|
| 14 |   is possible to run package test suites. Running the test suite for a
 | 
|---|
| 15 |   newly built package is a good idea because it can provide a <quote>sanity
 | 
|---|
| 16 |   check</quote> indicating that everything compiled correctly. A test suite
 | 
|---|
| 17 |   that passes its set of checks usually proves that the package is
 | 
|---|
| 18 |   functioning as the developer intended. It does not, however, guarantee
 | 
|---|
| 19 |   that the package is totally bug free.</para>
 | 
|---|
| 20 | 
 | 
|---|
| 21 |   <para>Some test suites are more important than others. For example, the test
 | 
|---|
| 22 |   suites for the core toolchain packages—GCC, Binutils,
 | 
|---|
| 23 |   and Glibc—are of the utmost
 | 
|---|
| 24 |   importance due to their central role in a properly functioning system.
 | 
|---|
| 25 |   The test suites for GCC and Glibc can take a very long time to complete,
 | 
|---|
| 26 |   especially on slower hardware, but are strongly recommended.</para>
 | 
|---|
| 27 | 
 | 
|---|
| 28 |   <para>A common issue with running the test suites for Binutils and GCC
 | 
|---|
| 29 |   is running out of pseudo terminals (PTYs). This can result in a high
 | 
|---|
| 30 |   number of failing tests. This may happen for several reasons, but the
 | 
|---|
| 31 |   most likely cause (if you chrooted) is that the host system does not have the
 | 
|---|
| 32 |   <systemitem class="filesystem">devpts</systemitem> file system set up
 | 
|---|
| 33 |   correctly. This issue is discussed in greater detail at
 | 
|---|
| 34 |   <ulink url="&faq-root;#no-ptys"/>.</para>
 | 
|---|
| 35 | 
 | 
|---|
| 36 |   <para>Sometimes package test suites will fail, but for reasons which the
 | 
|---|
| 37 |   developers are aware of and have deemed non-critical. Consult the logs located
 | 
|---|
| 38 |   at <ulink url="&test-results;"/> to verify whether or not these failures are
 | 
|---|
| 39 |   expected. This site is valid for all tests throughout this book.</para>
