Hi I have installed the boost 1.31.0 and have been trying to compile the test examples that were there in the regular expression library.But the compiler isnt able to identify the header files.So I did include the path during my compilation by using the -I and the path name..However it is still inable to compile as it is unable to include or search the indented header files... This is my first time I have been using this kind of library.Can someone suggest a way so that I can start using the library.Is there a way in which I can directly compile nad run the files without having to go through the ordeal of specifying the path at compile time everytime I wanna use the file Any help will be highly appreciated.
