Installation of Ruby

First, resolve some issues introduced by glibc-2.32: 

patch -Np1 -i ../ruby-2.7.1-glibc_fix-1.patch

Install Ruby by running the following command: 

./configure --prefix=/usr   \
            --enable-shared \
            --docdir=/usr/share/doc/ruby-2.7.1 &&
make

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

make capi

To test the results, issue: make check. There are over 21,000 tests. Some tests related to ipv6 may indicate errors. If the tests are run in a directory that has a world writable component (e.g. /tmp) then several additional tests may fail. One test related to the time function may fail due to a change in expectations as a result of glibc-2.31.

Now, as the root user: 

make install

Command Explanations

--disable-install-doc: This switch disables building and installing rdoc indexes and C API documents.

--disable-install-rdoc: This switch disables building and installing rdoc indexes.

--disable-install-capi: This switch disables building and installing C API documents.
