<caution>
<para>
If you are upgrading JS68 from a previously installed old version,
save all work and exit your GNOME Session if you have one running.
Replacing the JS68 binary will cause the GNOME Shell to crash and
return you to your display manager or TTY. After installing the new
version, reinstall <xref linkend="gjs"/>. Polkit is unaffected.
</para>
</caution>
<para>
First, apply a patch so we can run the shipped build scripts with
Python 3, instead of the EOL'ed Python 2:
</para>
<screen><userinput remap="pre">patch -Np1 -i ../js68-&JS68-version;-python_3-1.patch</userinput></screen>
<para>
Install <application>JS</application> by running the following
commands:
</para>
&shell-env;
<screen><userinput>sed '21,+4d' -i js/moz.configure &amp;&amp;
mkdir mozjs-build &amp;&amp;
cd mozjs-build &amp;&amp;
CC=gcc CXX=g++ LLVM_OBJDUMP=/bin/false \
../js/src/configure --prefix=/usr \
--with-intl-api \
--with-system-zlib \
--with-system-icu \
--disable-jemalloc \
--disable-debug-symbols \
--enable-readline \
--enable-unaligned-private-values &amp;&amp;
make</userinput></screen>
<para>
This package does not come with a working test suite.
</para>
<para>
Now, as the <systemitem class="username">root</systemitem> user:
</para>
<screen role="root"><userinput>make install &amp;&amp;
rm -v /usr/lib/libjs_static.ajs</userinput></screen>
</sect2>
<sect2 role="commands">
<title>Command Explanations</title>
<para>
<command>sed '21,+4d' js/moz.configure</command>: The building system
searches for <command>rustc</command> and <command>cargo</command> but
doesn't actually use them. Remove the reference to them so we can
build JS68 without <xref role="nodep" linkend="rust"/> installed.
</para>
<para>
<envar>CC=gcc CXX=g++</envar>: Upstream now prefers
<application>clang</application>, override it like other Mozilla
packages in BLFS book.
</para>
<para>
<envar>LLVM_OBJDUMP=/bin/false</envar>: The building system searches
for <command>llvm-objdump</command> but doesn't actually use it.
Override it so we can build JS68 without
<xref role="nodep" linkend="llvm"/> installed.
</para>
<para>
<parameter>--with-*</parameter>: These parameters allow the build system
to use system versions of the above libriares. These are required for
stability.
</para>
<para>
<parameter>--enable-readline</parameter>: This switch enables Readline
support in the JS shell.
</para>
<para>
<parameter>--disable-jemalloc</parameter>: This switch disables the
internal memory allocator used in JS68. jemalloc causes a conflict with glibc.
</para>
<para>
<parameter>--disable-debug-symbols</parameter>: Don't generate debug
symbols since they are very large and most users won't need it. Remove
it if you want to debug JS68.
</para>
<para>
<parameter>--enable-unaligned-private-values</parameter>: This switch
allows the code using JS68 not to align all pointers in the same way
JS68 does. <xref linkend="gjs"/> requires JS68 to be built with this
switch.
</para>
<para>
<command>rm -v /usr/lib/libjs_static.ajs</command>: Remove a large
static library which is not used by any BLFS package.
</para>
