    Compiling speed

    do c++ programs take longer to compile than equivalent programs writen in c ? (non OOP of course).
    or is it just me, caught in a strange time warp

    As far as i know, you must really have a huge source for
    it to noticable compile slower a 100 program compiles just as
    fast as a 1000 line program

    C++ does shift a lot of work on the compiler......especially with templates........but unless you are compiling a massive program then it shouldnt cause too much hassle IMO

    Yes. Of course most compilers are smart enough not to recompile from scratch every time so that speeds things up considerably. Though C++ compilation is noticeably slower than C even with the most current of compilers.

    My best code is written with the delete key.

    Anyone ever try to compile KDE from source? It's definetely not a quick experience.

    Well remember that you aren't just using the compiler there. KDE would make use of a parser-generator, lots of linking and relinking, et cetera.

    And I think XFree86 takes even longer than KDE, but that might just be my impression because the XF86 codebase has to be edited manually to make it compatible with bison 1.75.
