%general-entities; ]> $LastChangedBy$ $Date$ js68 JS is Mozilla's JavaScript engine written in C. JS68 is taken from Firefox. Package Information Download (HTTP): Download (FTP): Download MD5 sum: &js68-md5sum; Download size: &js68-size; Estimated disk space required: &js68-buildsize; Estimated build time: &js68-time; JS68 Dependencies Required , , , , and Optional (with Clang) and User Notes: 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 . Polkit is unaffected. Unlike most other packages in BLFS, the instructions below require you to untar firefox-&JS68-version;esr.tar.xz and change into the firefox-&JS68-version; folder. Install JS by running the following commands: sed '21,+4d' -i js/moz.configure && mkdir obj && cd obj && 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 && make This package does not come with a working test suite. Now, as the root user: make install && rm -v /usr/lib/libjs_static.ajs sed '21,+4d' js/moz.configure: The building system searches for rustc and cargo but doesn't actually use them. Remove the reference to them so we can build JS68 without installed. CC=gcc CXX=g++: Upstream now prefers clang, override it like other Mozilla packages in BLFS book. LLVM_OBJDUMP=/bin/false: The building system searches for llvm-objdump but doesn't actually use it. Override it so we can build JS68 without installed. --with-*: These parameters allow the build system to use system versions of the above libriares. These are required for stability. --enable-readline: This switch enables Readline support in the JS shell. --disable-jemalloc: This switch disables the internal memory allocator used in JS68. jemalloc causes a conflict with glibc. --disable-debug-symbols: 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. --enable-unaligned-private-values: This switch allows the code using JS68 not to align all pointers in the same way JS68 does. requires JS68 to be built with this switch. rm -v /usr/lib/libjs_static.ajs: Remove a large static library which is not used by any BLFS package.
