|
|
<para>This package and the next three (Expect, DejaGNU, and Check) are
|
|
installed to support running the test suites for GCC and Binutils and other
|
|
packages. Installing four 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>Note that the Tcl package used here is a minimal version needed
|
|
to run the LFS tests. For the full package, see the
|
|
<ulink url='&blfs-book;general/tcl.html'>BLFS Tcl procedures</ulink>.</para>
|
|
|
|
<para>Prepare Tcl for compilation:</para>
|
|
|
|
<screen><userinput remap="configure">cd unix
|
|
./configure --prefix=/tools</userinput></screen>
|
|
|
|
<para>Build the package:</para>
|
|
|
|
<screen><userinput remap="make">make</userinput></screen>
|
|
|
|
<para>Compilation is now complete. As discussed earlier, running the test
|
|
suite is not mandatory for the temporary tools here in this chapter. To run
|
|
the Tcl test suite anyway, issue the following command:</para>
|
|
|
|
<screen><userinput remap="test">TZ=UTC make test</userinput></screen>
|
|
|
|
<para>The Tcl test suite may 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), 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 <xref linkend="chapter-bootscripts"/>.</para>

<para>Install the package:</para>

<para>Make the installed library writable so debugging symbols can
|
|
be removed later:</para>
|
|
|
|
<screen><userinput remap="install">chmod -v u+w /tools/lib/libtcl&tcl-major-version;.so</userinput></screen>
|
|
|
|
<para>Install Tcl's headers. The next package, Expect, requires them
|
|
to build.</para>
|
|
|
|
<screen><userinput remap="install">make install-private-headers</userinput></screen>
|
|
|
|
<para>Now make a necessary symbolic link:</para>
