The shared library (FeResPost.so or FeResPost.dll) is delivered with “FeResPost.rb” ruby file. This file is the ‘main” file that loads the shared library and defines the elements that allow to “coerce” the arguments of “Result” class operators. (See section I.7.)
The files should be copied into the ruby installation library directory. The files can also be installed in another directory, but then the access path must be specified to ruby. (For example, with “-I” option.) You can also install them in any directory that suits you and ensure that “RUBYLIB” environment variable points to that directory.
