* How to compile and install This is what you need to do to compile and install Ruby: 1. If ./configure does not exist or is older than configure.in, run autoconf to (re)generate configure. 2. Run ./configure, which will generate config.h and Makefile. 3. Edit defines.h if you need. Usually this step will not be needed. 4. Remove comment mark(#) before the module names from ext/Setup (or add module names if not present), if you want to link modules statically. If you don't want to compile non static extension modules (probably on architectures which does not allow dynamic loading), remove comment mark from the line "#option nodynamic" in ext/Setup. 5. Run make. 6. Optionally, run 'make test' to check whether the compiled Ruby interpreter works well. If you see the message "test succeeded", your ruby works as it should (hopefully). 7. Run 'make install' You may have to be a super user to install ruby.
