New to SFML -- CMake Errors

[MikeF]

Hello,

I've recently decided to give SFML 2.0 a try. I'm following http://www.sfml-dev.org/tutorials/2.0/compile-with-cmake.php in order to compile the source code manually (I want to use C++11 features in my source code, otherwise I wouldn't bother with CMake).

I've got the source code in a folder on my desktop called SFML2 and a separate folder on my desktop called SFML2-Build that will store the results of the build.

After filling out these two directories at the top of the CMake GUI, I went into Configure, selected Unix Makefiles, and then Specify native compilers, as per the 2.0 c++11 build instructions. Then I went on to select clang for C and clang++ for the c++ compiler, subsequently pressing Done on that same window.

However, as soon as I click done, I get a bunch of errors, and the build is deemed unsuccessful. I've followed the tutorials to a T so I'm not seeing what could be going wrong here. The source code is the latest version from GitHub.

Here is the error output log:

Thanks for any help with this, I can't wait to get this up and running!

Are you using OS X?

If so you can find some binaries with C++11 support here.

[MikeF]

Yup, I'm using Mountain Lion. I'll try this out right now, thanks for the link, this looks perfect!

[MikeF]

Hmmm, I actually think the problem was that I created the folders inside of the Developer folder, which was read-only, and those folders inheritied that read-only aspect so the tmp file wasn't being written, causing a chain-reaction of errors. CMake seems to be working now

[MikeF]

So I was able to get the dylibs generated and the XCode template installed. I made a project with the following settings:



As I said before, I wish to use C++11 in this project and I figured if I want to launch in Debug, I'll need to use Dylibs, so I opted for those in CMake instead of a Framework (Release was checked off in CMake, so I'm assuming I'm correct in choosing Dylibs instead of Dylibs (Debug) from the dropdown menu).

However, when I try to build this example project, I receive linker errors:

Any ideas what I'm doing wrong here?

[Laurent]

Did you set CMAKE_OSX_ARCHITECTURES to "i386;x86_64" when you compiled SFML?

[MikeF]

Nope, I must have missed that instruction. I actually ended up following this great tutorial: http://www.mjbshaw.com/2013/02/building-sfml-2-with-c11-on-os-x.html and it now works. My only question is about the frameworks vs. dylibs. In terms of development, does using a framework limit me in terms of debugging abilities? I'm kind of confused about the distinction.

Thanks

[Hiura]

In terms of development, does using a framework limit me in terms of debugging abilities? I'm kind of confused about the distinction.

It doesn't matter much as you don't need to debug SFML code but your code only (theoretically, of course). I would recommend the Framework version simply because everything is self contained but dylibs works fine too.



The «Dylibs (Debug)» option for the template only tells Xcode to use SFML debug dylibs in debug. So you don't really need this option unless you're trying to add new features to SFML and need to debug SFML binaries.
