In archive “FeResPost_5.2.0_LINUX_32.7z” the binaries contain ruby wrappers and C++ library:
“OUTPUTS/lib” directory contains the file “libFeResPost_5.2.0.so” that corresponds to the FeResPost C++ library without any wrapper. If you intend to work with the C++ shared library, this file should be located in a library standard directory, or in a library pointed to by environment variable “LD_LIBRARY_PATH”.
“OUTPUTS/include” directory and its subdirectories contain FeResPost C++ headers. You have no use of these files unless you wish to develop your own wrapper for FeResPost (for use with Python, Perl, Java...), or use FeResPost C++ library in one of your C++ applications. So most of you can forget this directory.
“OUTPUTS/RUBY/” directory contains RUBY extensions (in different sub-directories).
“OUTPUTS/PYTHON/” directory contains Python extensions for Python (in different sub-directories).
The ruby and python libraries must be used with the appropriate 32-bit distribution of ruby or python. (Note that 32-bit programs and libraries can be used on 32-bit or 64-bit LINUX installations.)
