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
33 <para>Prepare Tcl for compilation:</para>
35 <screen><userinput>cd unix
36 ./configure --prefix=/tools</userinput></screen>
38 <para>Build the package:</para>
40 <screen><userinput>make</userinput></screen>
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
50 will be given later on in <xref linkend="chapter-bootscripts"/>.</para>
