Hi Everyone, Can't get my head around something that is probably very very simple I have some code like this :- std::string data_location data_location = "/usr/local/hardcodedpath" How can i set "/usr/local/hardcodedpath" at compile time? Is there an easy C++ way of using preprocessors, i've tried passing values over -DMY_LOCATION and using data_location = MY_LOCATION but as the string is unquoted this fails. It does not seem possible to pass quoted values via the preprocessor. The only thing i can think to do is to run sed at the file first? Any other suggestions TIA Robin -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
