General / Can't Link SFML 2.0 on Mac OSX 10.7.2

« on: October 30, 2011, 01:17:53 pm »

[updated]

Hey,

i've been trying to make SFML works, but all in vain.

I first tried with the SFML 2.0 snapshot, and then with the SFML git

So here's what i've done:

I retrieved the whole repository. and then used cmake. While doing cmake, the only warnings that i got were about some unbound keycodes. Otherwise it was successful. libs were created in SFML/lib (i tried both static & dynamic libs)
So here's the content of SFML/lib/ :

Code: [Select]


libsfml-audio-s.a libsfml-graphics.dylib libsfml-system.2.dylib
libsfml-audio.2.0.dylib libsfml-network-s.a libsfml-system.dylib
libsfml-audio.2.dylib libsfml-network.2.0.dylib libsfml-window-s.a
libsfml-audio.dylib libsfml-network.2.dylib libsfml-window.2.0.dylib
libsfml-graphics-s.a libsfml-network.dylib libsfml-window.2.dylib
libsfml-graphics.2.0.dylib libsfml-system-s.a libsfml-window.dylib
libsfml-graphics.2.dylib libsfml-system.2.0.dylib


here's what my Makefile project looks like:

Code: [Select]



# Tools
CXX=            g++
CFLAGS=         -Wall -ansi -lsfml-graphics
CLIBS =         -lsfml-graphics -lsfml-window -lsfml-system

# Dirs
SRCDIR=         src/
INCDIR=         include/
OBJDIR=         obj/

# Files
CPPFILES=       $(shell (for f in $$(find ./$(SRCDIR) -type f -name *.cpp); do basename $$f; done;))
OBJFILES=       $(CPPFILES:.cpp=.o)

# Output
BIN=            td610

###############################################################################
# Rules
###############################################################################
vpath   %.cpp $(SRCDIR)

all:    $(OBJFILES)
        $(CXX) -o$(BIN) $(addprefix $(OBJDIR),$(OBJFILES))


%.o:    %.cpp
        @echo "building $@ ($<)"
        @mkdir -p obj
        $(CXX) -o $(OBJDIR)$@ -c $< $(CFLAGS) $(CLIBS) -I$(INCDIR) -L/Users/Willy/Dev/SFML/lib/


And here's the result when I start compiling

Code: [Select]

        while ( win.IsOpened() ) {
                win.Clear();
                win.Display();
        }
        return 0;
}                    


I'm not really experienced with Mac stuff, since I do not own any.

I just took a look at the System information and here's what I get :

Code: [Select]


Model Name: MacBook
  Model Identifier: MacBook6,1
  Processor Name: Intel Core 2 Duo
  Processor Speed: 2,26 GHz
  Number of Processors: 1
  Total Number of Cores: 2
  L2 Cache: 3 MB
  Memory: 4 GB
  Bus Speed: 1,07 GHz


I can't tell if it's a 64bits architecture nor a 32bits. I'd say it's a 64 one

Any help would be appreciated,

Salepate

Edit: I just happened to fix the undefined references, it now works but i still get those warnings. might I just ignore it?

Graphics / Color problems

« on: October 13, 2010, 01:45:52 pm »

Hey, I've been manipulating Shapes and colors recently and it seems like I don't get something.

When I create my shapes, I always use Color::White, then by using SetColor(), I change its color to the one I want

Code: [Select]


// col is a given parameter : const Color &col
    Color _sColor = col;
    Shape _shape = Shape::Rectangle(0, 0, _size.x, _size.y, Color::White, 1, Color::Black);
    _shape.SetColor(col);


That's working perfectly, but for some unknown reasons, if I try to apply again the same color, it gets darker.

Code: [Select]


_shape.SetColor(_sColor);


I've been double checking what I've done wrong, but I can't see the problem.

Any help would be appreciated, thanks!
