<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 (we recommend not running them), these packages
|
|
are still required to run the test suites in <xref
|
|
linkend="chapter-building-system"/>.</para>

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

<para>Build the package:</para>

<para>To test the results, issue: <userinput>TZ=UTC make
|
|
test</userinput>. However, 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. More information on the
|
|
TZ environment variable will be provided in <xref
