Qt Creator + SFML on OSX Mavericks w/ clang
« on: May 17, 2014, 03:37:07 am »
I am no expert with linking, so I may be doing something stupid, but anyways, I have a strange problem and cannot for the life of me make sense of it.

I am using Qt Creator on OSX Mavericks, compiling with clang. I am NOT using the Qt framework in my project; just using the IDE.

Most of SFML works as expected; however, for some strange reason, I cannot use Image::loadFromFile or Texture::loadFromFile or I get linking errors (Undefined symbols for architecture x86_64). I have compiled and recompiled SFML and tried everything I can think of. I can compile SFML apps via command line, but not within Qt Creator. Does anyone know what the issue might be?

The compiler output is:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ -headerpad_max_install_names -Wl,-syslibroot,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk -mmacosx-version-min=10.6 -o test.app/Contents/MacOS/test main.o   -L/usr/local/lib -lsfml-audio-d -lsfml-graphics-d -lsfml-network-d -lsfml-window-d -lsfml-system-d
Undefined symbols for architecture x86_64:
  "sf::Image::loadFromFile(std::string const&)", referenced from:
      _main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [test.app/Contents/MacOS/test] Error 1
21:30:14: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project test (kit: Desktop Qt 5.2.1 clang 64bit)
When executing step 'Make'

This is frustrating me. Thanks people.

Okay, I will try compiling as directed in that tutorial. However, the problem is still not clear to me; are you saying that Qt Creator is using the wrong compiler? If so, shouldn't I be able to simply change the compiler it is using?

Ah, or are you saying that SFML is by default configured to compile for Xcode with the C++11 compiler and Qt Creator isn't?

No, what I say is the following: your SFML binaries and your project are not compiled with the same settings.

You can configure QtC to use the same settings as your SFML binaries – or – recompile SFML with your project settings.

Well ultimately I want to link with the Qt framework, so I'll probably stick with whatever it was compiled with. Do you know specifically what settings are in conflict?

I'll just try specifying the compilers in CMake as shown in the tutorial and see if that works.
