  42
  43     <para>This package and the next two (Expect and DejaGNU) are
  44     installed to support running the test suites for GCC and Binutils and other
  45     packages.  Installing three packages for testing purposes may seem
  46     excessive, but it is very reassuring, if not essential, to know that the
  47     most important tools are working properly. Even if the test suites are not
  48     run in this chapter (they are not mandatory), these packages are required
  49     to run the test suites in <xref linkend="chapter-building-system"/>.</para>
  50
  51     <para>Note that the Tcl package used here is a minimal version needed
  52     to run the LFS tests.  For the full package, see the
  53     <ulink url='&blfs-book;general/tcl.html'>BLFS Tcl procedures</ulink>.</para>

  64     <para>Compilation is now complete. As discussed earlier, running the test
  65     suite is not mandatory for the temporary tools here in this chapter. To run
  66     the Tcl test suite anyway, issue the following command:</para>
  67
  68 <screen><userinput remap="test">TZ=UTC make test</userinput></screen>
  69
  70     <para>The Tcl test suite may experience failures under certain host
  71     conditions that are not fully understood. Therefore, test suite failures
  72     here are not surprising, and are not considered critical. The
  73     <parameter>TZ=UTC</parameter> parameter sets the time zone to Coordinated
  74     Universal Time (UTC), but only
  75     for the duration of the test suite run. This ensures that the clock tests
  76     are exercised correctly. Details on the <envar>TZ</envar> environment
  77     variable are provided in <xref linkend="chapter-bootscripts"/>.</para>
