Installation of JS

Install JS by running the following commands:

[Note]

Note

If you are compiling this package in chroot you must do two things. First, as the root user, ensure that /dev/shm is mounted. If you do not do this, the Python configury will fail with a traceback report referencing /usr/lib/pythonN.N/multiprocessing/synchronize.py. Run:

mountpoint /dev/shm >/dev/null ||
 mount -t tmpfs devshm /dev/shm

Second, either as the root user export the $SHELL environment variable using export SHELL=/bin/sh or else prepend SHELL=/bin/sh when running the configure command.

mkdir mozjs-build &&
cd    mozjs-build &&

../js/src/configure --prefix=/usr       \
                    --with-intl-api     \
                    --with-system-zlib  \
                    --with-system-icu   \
                    --disable-jemalloc  \
                    --enable-readline   &&
make

This package does not come with a working test suite.

Now, as the root user:

make install

Command Explanations

--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 JS60. jemalloc causes a conflict with glibc.
