| 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>
