      Install <application>NSPR</application> by running the following commands:
    </para>

<screen><userinput>cd nspr &amp;&amp;

sed -i '/^RELEASE/s|^|#|' pr/src/misc/Makefile.in &amp;&amp;
sed -i 's|$(LIBRARY) ||'  config/rules.mk         &amp;&amp;

make</userinput></screen>

    <para>
      The test suite is designed for testing changes to nss or nspr and is
      not particularly useful for checking a released version (e.g. it needs
      to be run on a non-optimized build with both nss and nspr directories
      existing alongside each other). For further details, see the Editor Notes
      for nss at <ulink url="&blfs-wiki;/nss"/>

    <para>
      <command>sed -ri '/^RELEASE/s/^/#/' pr/src/misc/Makefile.in</command>:
      This sed disables installing two unneeded scripts.
    </para>

    <para>
      <command>sed -i 's#$(LIBRARY) ##' config/rules.mk</command>: This sed disables
      installing the static libraries.
    </para>

    <para>
      <parameter>--with-mozilla</parameter>: This parameter adds Mozilla support
      to the libraries (required if you want to build any other Mozilla
      products and link them to these libraries).
    </para>

    <para>
      <parameter>--with-pthreads</parameter>: This parameter forces use of the
      system pthread library.
    </para>

    <para>
      <parameter>--enable-64bit</parameter>: The --enable-64bit parameter is
      <emphasis>required</emphasis> on an x86_64 system to prevent
      <command>configure</command> failing with a claim that this is a system
      without pthread support. The [ $(uname -m) = x86_64 ] test ensures it has
      no effect on a 32 bit system.
