Hey all, I'm having some trouble compiling some sfml in the terminal. I have compiled and run sfml in the terminal before, although that was a few months ago, and before i upgraded to El Capitan. I still seem to be able to run Xcode projects just fine; It is nice thought to be able to run small test directly in the terminal.

I'm getting the following error:

     mycomputer:sfmltest me$ g++ sfmltest2.cpp -lsfml-system
     sfmltest2.cpp:1:10: fatal error: 'SFML/System.hpp' file not found
     #include <SFML/System.hpp>
              ^
     1 error generated.


I think i have SFML installed correctly:
  • lib is in usr/local/lib
  • include is in usr/local/include
  • the contents of frameworks and extlibs are in Library/Frameworks

I got info on g++

    mycomputer:sfmltest me$ g++ -v
    Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/c++/4.2.1
    Apple LLVM version 7.0.2 (clang-700.1.81)
    Target: x86_64-apple-darwin15.2.0
    Thread model: posix

and my $PATH

    mycomputer:sfmltest me$ echo $PATH
    /Users/me/perl5/perlbrew/bin:/Users/me/perl5/perlbrew/perls/perl-5.16.0/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin


I noticed that my install location wasnt included. Is this a problem? what is the point of the compiler flags -lsfml-system / -framework sfml-system?

I've tried both dylibs and framworks now, and i get the same error. and I'm hoping to get some advice before i go and screw up my default paths.

Thanks,
kipbits

There was a related question a few days ago: http://en.sfml-dev.org/forums/index.php?topic=19559.msg140951#msg140951

Note a few things:
 - No need to edit paths in principle.
 - dylibs & frameworks are mutually exclusive: you only one of them to use SFML.
 - -I, -L, -l & -framework are compiler flags; I'll let you RTFM to learn how to use them and what they mean. ;-)
 - but you usually want to use `-I/usr/local/include -L/usr/local/lib -lsfml-...`.

g++ sfmltest2.cpp -I/usr/local/include -L/usr/local/lib -lsfml-audio -lsfml-window -lsfml-system

Well That seemed to fix it. Thanks!

Funny before updating to El Capitan I could run it without the extra flags:
      g++ sfmltest2.cpp -lsfml-audio -lsfml-window -lsfml-system

Any Idea what they did with the new OS X?

Nope, sorry. Maybe they changed the compilation flags when they built clang the last time (because you're not really using g++, are you?)...
