Installation of Ruby

Install Ruby by running the following command:

./configure --prefix=/usr      \
            --enable-shared    \
            --without-valgrind \
            --docdir=/usr/share/doc/ruby-3.2.1 &&
make

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

make capi

To test the results, issue: make check. There are over 25,000 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. A few tests may fail due to system configuration expectations.

Now, as the root user:

make install
[Note]

Note

If you have Ruby-On-Rails applications installed and did an upgrade of Ruby by installing this package, you might need to run an update there, too (as the root user):

cd /path/to/web/app
bundle update rake

and restart the webserver which serves the application.

Command Explanations

--enable-shared: This switch enables building the libruby shared library.

--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.

--without-baseruby: This switch prevents using the system ruby if it is already installed. The build system will use the newly built version instead.
