so i need to use boost/regex for regular expressions. someone told me that it needs to be built. the first problem is boost doesnt tell you how to build it (i dont think... if im wrong could someone give me a link?) and the second is i did sudo apt-get install libboostsomething. i dont remember the exact name of the package. it installed but i dont know how i would build it when its installed. if anyone could help i would be very grateful
