|
|
<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>

<screen><userinput>cd unix
|
|
./configure --prefix=/tools</userinput></screen>

<para>Build the package:</para>
|
|
|
|
<screen><userinput>make</userinput></screen>
|
|
|
|
<para>To test the results, issue: <userinput>TZ=UTC make test</userinput>.
|
|
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
