Installation of JS

[Note]

Note

This package can be installed without problems, if you have installed JS-17.0.0. It is necessary to set SHELL=/bin/bash if you are working in chroot.

Install JS by running the following commands: 

cd js/src &&

sed -i 's/(defined\((@TEMPLATE_FILE)\))/\1/' config/milestone.pl &&

./configure --prefix=/usr       \
            --enable-readline   \
            --enable-threadsafe \
            --with-system-ffi   \
            --with-system-nspr &&
make

To test the results, issue: make check.

Now, as the root user: 

make install &&
find /usr/include/mozjs-24/         \
     /usr/lib/libmozjs-24.a         \
     /usr/lib/pkgconfig/mozjs-24.pc \
     -type f -exec chmod -v 644 {} \;
