|
<para>This package and the next two (Expect and DejaGNU) are installed
|
|
to support running the test suites for GCC and Binutils. Installing
|
|
three packages for testing purposes may seem excessive, but it is very
|
|
reassuring, if not essential, to know that the most important tools are
|
|
working properly. Even if the test suites are not run in this chapter
|
|
(they are not mandatory), these packages are required to run the test
|
|
suites in <xref linkend="chapter-building-system"/>.</para>
|

<para>Prepare Tcl for compilation:</para>

<para>To test the results, issue:</para>

<screen><userinput remap="test">TZ=UTC make test</userinput></screen>
|
|
|
|
<para>The Tcl test suite is known to experience failures under certain host
|
|
conditions that are not fully understood. Therefore, test suite failures
|
|
here are not surprising, and are not considered critical. The
|
|
<parameter>TZ=UTC</parameter> parameter sets the time zone to Coordinated
|
|
Universal Time (UTC), also known as Greenwich Mean Time (GMT), but only
|
|
for the duration of the test suite run. This ensures that the clock tests
|
|
are exercised correctly. Details on the <envar>TZ</envar> environment
|
|
variable are provided in <xref linkend="chapter-bootscripts"/>.</para>
