Thanks Maarten, How would I go about linking -lboost_system and -lboost_thread? I'm sorry, I am just starting out with Linux. I should say that I am using Ubuntu 14.04. Thanks in advance for any and all help you can provide.

Hello Leon, Thanks for your quick response! I'm not sure if I understand what you mean (my fault not yours). I typed "-lboost_system" and "-lboost_thread" into the command line of the terminal however both types it returned the error message "command not found". I assume you mean to add these lines to the .bashrc or to the install file for openfoam. Is this correct? You are correct that the boost files are downloaded to the /usr/lib, however searching through the lib directory I find that the most similar libraries to those discussed are the "libboost_system.so.1.54.0" and "libboost_thread.so.1.54.0" files, are these the correct files? Again thank you for all your help, I really appreciate it.

Exactly the way you've written: add "-lboost_system -lboost_thread" to the command line. If you installed Ubuntu's boost-all-dev package the libraries should already be under /usr/li where linker will find t hem;; if not add -L<path-to-directory-containing-libraries> to tell the linker where the libraries are.
