<title>Installation of Tcl</title>
|
|
|
|
<para>This package and the next two are only installed to be able to run the
|
|
test suites for GCC and Binutils. Installing three packages just for testing
|
|
purposes may seem like overkill, but it is very reassuring, if not essential,
|
|
to know that our most important tools are working properly. Even if you are
|
|
not running the test suites here in this chapter as per our recommendation,
|
|
these packages are still required for running the test suites in the next
|
|
chapter.</para>

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

<para>Build the package:</para>

<screen><userinput>make</userinput></screen>
|
|
|
|
<para>(If you insist on testing the results, then 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 <emphasis>TZ=UTC</emphasis> 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 the clock
|
|
tests are exercised correctly. More information on the TZ environment variable
|
|
will be given later on in <xref linkend="chapter-bootscripts"/>.)</para>
