25 | <para>This package and the next two are only installed to support running the
|
---|
26 | test suites for GCC and Binutils. Installing three packages just for testing
|
---|
27 | purposes may seem like overkill, but it is very reassuring, if not essential,
|
---|
28 | to know that our most important tools are working properly. Even if the
|
---|
29 | the test suites are not run in this chapter (we recommend not running them),
|
---|
30 | these packages are still required to run the test suites in the next
|
---|
31 | chapter.</para>

42 | <para>If you want to test the results, then issue:
|

43 | <userinput>TZ=UTC make test</userinput>. However, the Tcl test suite is known
|
---|
44 | to experience failures under certain host conditions that are not fully
|
---|
45 | understood. Therefore, test suite failures here are not surprising, and are not
|
---|
46 | considered critical. The <emphasis>TZ=UTC</emphasis> parameter sets the time
|
---|
47 | zone to Coordinated Universal Time (UTC) also known as Greenwich Mean Time
|
---|
48 | (GMT), but only for the duration of the test suite run. This ensures the clock
|

49 | tests are exercised correctly. More information on the TZ environment variable
