15 | <para>Most packages provide a test suite. Running the test suite for a |
---|
16 | newly built package is a good idea because it can provide a <quote>sanity |
---|
17 | check</quote> indicating that everything compiled correctly. A test suite |
---|
18 | that passes its set of checks usually proves that the package is |
---|
19 | functioning as the developer intended. It does not, however, guarantee |
---|
20 | that the package is totally bug free.</para> |
---|
21 | |
---|
22 | <para>Some test suites are more important than others. For example, |
---|
23 | the test suites for the core toolchain packages—GCC, Binutils, and |
---|
24 | Glibc—are of the utmost importance due to their central role in a |
---|
25 | properly functioning system. The test suites for GCC and Glibc can |
---|
26 | take a very long time to complete, especially on slower hardware, but |
---|
27 | are strongly recommended.</para> |
---|
28 | |
---|
29 | <note> |
---|
30 | <para>It is not possible to run testsuites when cross-compiling, so there |
---|
31 | are no instructions given for running testsuites until |
---|
32 | <xref linkend="chapter-building-system"/>.</para> |
---|
33 | </note> |
---|
34 | |
---|
35 | <para>A common issue with running the test suites for Binutils and GCC |
---|
36 | is running out of pseudo terminals (PTYs). This can result in a high |
---|
37 | number of failing tests. This may happen for several reasons, but the |
---|
38 | most likely cause is that the host system does not have the |
---|
39 | <systemitem class="filesystem">devpts</systemitem> file system set up |
---|
40 | correctly. This issue is discussed in greater detail at |
---|
41 | <ulink url="http://www.linuxfromscratch.org/lfs/faq.html#no-ptys"/>.</para> |
---|
42 | |
---|
43 | <para>Sometimes package test suites will fail, but for reasons which the |
---|
44 | developers are aware of and have deemed non-critical. Consult the logs located |
---|
45 | at <ulink url="&test-results;"/> to verify whether or not these failures are |
---|
46 | expected. This site is valid for all tests throughout this book.</para> |
