README SYSTEM REQUIREMENTS: rTANDEM uses 'expat' and 'pthread' libraries. Their avalability might vary according to operating system. expat: The expat library should be available on OSX since 10.4. The expat library for linux can be downloaded at http://sourceforge.net/projects/expat/files. The expat library for Windows can be downloaded at http://sourceforge.net/projects/expat/files. pthread: The pthread library should be available on OSX since 10.3. The pthread library is available on most linux plateforms. A version of pthread is available for win-32 and can be downloaded at http://sourceware.org/pthreads-win32. When building from sources on Windows systems, linking against the expat library can be problematic. To circumvent this difficulty, create a directory structure like this one: C:\expat\i386 C:\expat\x64 Then place the 32 bit and 64 bits libraries respectively in C:\expat\i386\lib and C:\expat\x64\lib. Finally, create an environment variable LIB_EXPAT and set it to "C:/expat/". This should allow the build process to sucessfully link against the expat libraries.
