Having a hard time getting SFML to work with Clang

[Gan]

Hey, so far my project was working perfectly, but I needed to use some C++11 features for at attempt at higher resolution thread sleeping.
So I switched my compiler from LLVM GCC 4.2 to Apple LLVM 4.1.

Got these errors:

Undefined symbols for architecture i386:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

Quick google search revealed that I needed to re-compile the framework with the compiler I want to use. Did so with CMake and Xcode, put the new frameworks and stuff in the correct folders(according to the manual mac install doc) and my application still produces the same error.

So I made a new SFML project from the template and it won't compile with either compilers. It produces the errors:

I'm a bit at a loss. I figure I'm doing something quite wrong.

I can get Xcode to compile SFML just fine as dylibs but it produces an SH error when I try as frameworks.
Unix NMake compiles both dylibs and the frameworks just fine.

Apparently the only problem is I have no idea how to get those dylibs or frameworks into my Xcode project. And the Xcode template doesn't work for some reason.

I'm gonna give the tutorial another shot before calling it a night.

[Gan]

No dice, re-followed the tutorial, used the clang compiler, did the unix make commands and the SFML template still bugs out on me:

[Hiura]

Don't you have two versions installed on your computer ? one in /usr/local (dylibs) and one in /Library/Frameworks/ ?

[Acrobat]

You are using C++11 ?

[Gan]

Yes to both.

I might just need to purge my system of SFML and do a clean re-install.

[Gan]

I've come to the realization, I suck at linking libraries.

I just installed boost from the instructions, then tried to use it in a program. Linker errors. I get linker errors with SFML too....
Perhaps this is a sign that I'm not meant to go. Or it's a challenge from Mr.Destiny wanting to see how I'll overcome it.

[Gan]

Suck it Destiny! Just got my test boost program to compile. Turns out I have to add the dylibs to the program. Then set the header search path for the dylibs. Then set the library search path for the lib folder the dylibs are in. Then add the dylibs under "Link Binary With Libraries" in the build phases.

Okay okay, now Imma try this process with SFML.

[Gan]

No dice. Here's my errors and settings on the same page:


See anything wrong?


Edit: This is what I get when I try to use frameworks instead of the .a files:

[Hiura]

Okay.. I'm lost with all your attempts..

Could you summary, in one post :-), your situation. More specifically, I'd like to know the following :
- what version of SFML are you using
- what settings did you use the compile SFML (if you did it yourself)
- how did you install SFML
- what version of the template are you using (usually, it's the same version as SFML, but you could have installed them manually, so..)
- what are the project settings
- the current compilation errors (btw, you can copy and past them instead of taking a screenshot)
- and, of course, any other information that you think is relevant here

[Gan]

- what version of SFML are you using:
2.0 latest snapshot
- what settings did you use the compile SFML (if you did it yourself):
I followed the tutorial, using CMake and enabling c++11 features using the clang compiler and setting -stdlib=libc++. I'd tried this method with making frameworks, dylibs and .a files. And I have it set to install the xcode template
- how did you install SFML:
I ran sudo make install on the generated makefiles from CMake which should put the compiled libraries in library/frameworks or /usr/local/include and /usr/local/lib
- what version of the template are you using:
I'm using the template version it installed.
- what are the project settings:
For framework, I added the SFML.framework to the project, set it in the Link Libraries, and added "/Library/Frameworks" to the Framework Search Path
- the current compilation errors (btw, you can copy and past them instead of taking a screenshot):

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

- and, of course, any other information that you think is relevant here:
When I try to compile it for 32bit instead of 64 bit, it gives all the same errors and an extra warning:

ld: warning: ignoring file /Library/Frameworks/SFML.framework/SFML, file was built for unsupported file format ( 0xcf 0xfa 0xed 0xfe 0x 7 0x 0 0x 0 0x 1 0x 3 0x 0 0x 0 0x 0 0x 6 0x 0 0x 0 0x 0 ) which is not the architecture being linked (i386): /Library/Frameworks/SFML.framework/SFML

I'd tried this method with making frameworks, dylibs and .a files. And I have it set to install the xcode template

On OS X, and more generally on Unixes, using static linking for libraries is not recommended. Then, you only need one binary. I recommend frameworks, but dylibs do the same job.

For framework, I added the SFML.framework to the project, set it in the Link Libraries, and added "/Library/Frameworks" to the Framework Search Path

So you're not using the SFML template, right ?

The issue is the following : SFML.framework only contains header and should not be used for any other purpose than that. What you need to do is to add sfml-$module.framework to your project for every $module that you need.
