| 13 | <para>In the final-system build, you are no longer cross-compiling so it
|
|---|
| 14 | is possible to run package testsuites. Some test suites are more important
|
|---|
| 15 | than others. For example, the test suites for the core toolchain
|
|---|
| 16 | packages—GCC, Binutils, and Glibc—are of the utmost
|
|---|
| 17 | importance due to their central role in a properly functioning system.
|
|---|
| 18 | The test suites for GCC and Glibc can take a very long time to complete,
|
|---|
| 19 | especially on slower hardware, but are strongly recommended.</para>

|

| 21 | <para>A common issue with running the test suites for Binutils and GCC
|
|---|
| 22 | is running out of pseudo terminals (PTYs). This can result in a high
|
|---|
| 23 | number of failing tests. This may happen for several reasons, but the
|
|---|
| 24 | most likely cause is that the host system does not have the
|
|---|
| 25 | <systemitem class="filesystem">devpts</systemitem> file system set up
|
|---|
| 26 | correctly. This issue is discussed in greater detail at
|
|---|

|
|---|
| 29 | <para>Sometimes package test suites will fail, but for reasons which the
|
|---|
| 30 | developers are aware of and have deemed non-critical. Consult the logs located
|
|---|
| 31 | at <ulink url="&test-results;"/> to verify whether or not these failures are
|
|---|
| 32 | expected. This site is valid for all tests throughout this book.</para>
