User Notes:

Installation of Ruby

Install Ruby by running the following command:

./configure --prefix=/usr   \
            --enable-shared \
            --docdir=/usr/share/doc/ruby-2.6.4 &&

Optionally, build the CAPI documents by running the following commands:

make capi

To test the results, issue: make check. There are over 20,000 tests. Some tests (up to 0.5 percent) may fail. If the tests are run in a directory that has a world writable component (e.g. /tmp) then several additional tests may fail. Several jit (just-in-time) tests are known to fail.

Now, as the root user:

make install
