98 <para>
99 If you are upgrading JS68 from a previously installed old version,
100 save all work and exit your GNOME Session if you have one running.
101 Replacing the JS68 binary will cause the GNOME Shell to crash and
102 return you to your display manager or TTY. After installing the new
103 version, if GNOME Shell still doesn't work, reinstall
104 <xref linkend="gjs"/>.

109 <para>
110 Unlike most other packages in BLFS, the instructions below require you
111 to untar <filename>firefox-&JS68-version;esr.tar.xz</filename> and
112 change into the <filename>firefox-&JS68-version;</filename> folder.

115 <para>
116 Extracting the tarball
117 will reset the permissions of the current directory to 0755 if you
118 have permission to do that. If you do this in a directory where
119 the sticky bit is set, such
120 as <filename class="directory">/tmp</filename> it will end with error
121 messages:

129 <para>
130 This does finish with non-zero status, but it does
131 <emphasis>NOT</emphasis> mean there is a real problem.
132 Do not untar as the <systemitem class="username">root</systemitem> user
133 in a directory where the sticky bit is set - that will unset it.

184 <para>
185 <command>sed '21,+4d' js/moz.configure</command>: Firefox building
186 system searches for <command>rustc</command> and
187 <command>cargo</command>.
188 Since we are building the standalone JS engine instead of the entire
189 browser, they are not actually used.
190 Remove the reference to them so we can
191 build JS68 without <xref role="nodep" linkend="rust"/> installed.

193
194 <para>
195 <envar>CC=gcc CXX=g++</envar>: Upstream now prefers

197 packages in BLFS book.

199
200 <para>
201 <envar>LLVM_OBJDUMP=/bin/false</envar>: The firefox build system
202 searches for <command>llvm-objdump</command>.
203 Since we are building the standalone JS engine instead of the entire
204 browser, they are not actually used.
205 Override it so we can build JS68 without
206 <xref role="nodep" linkend="llvm"/> installed.

209 <para>
210 <parameter>--with-*</parameter>: These parameters allow the build system
211 to use system versions of the above libraries. These are required for
212 stability.

215 <para>
216 <parameter>--enable-readline</parameter>: This switch enables Readline
217 support in the JS shell.
218 </para>
219
220 <para>
221 <parameter>--disable-jemalloc</parameter>: This switch disables the
222 internal memory allocator used in JS68. jemalloc causes a conflict with glibc.
223 </para>
224
225 <para>
226 <parameter>--disable-debug-symbols</parameter>: Don't generate debug
227 symbols since they are very large and most users won't need it. Remove
228 it if you want to debug JS68.
229 </para>
230
231 <para>
232 <parameter>--enable-unaligned-private-values</parameter>: This switch
233 allows the code using JS68 not to align all pointers in the same way
234 JS68 does. <xref linkend="gjs"/> requires JS68 to be built with this
235 switch.
236 </para>
237
238 <para>
239 <command>rm -v /usr/lib/libjs_static.ajs</command>: Remove a large
