Problem configuring csfml2 with cmake

[Laurent]

You must have installed SFML 2 before, and if you did it successfully, the FindSFML.cmake file should have been copied to your CMake directory.

[atomen]

Sorry for reviving a thread, buy may I ask exactly what you mean by this:

the FindSFML.cmake file should have been copied to your CMake directory.

I am having trouble as well with compiling the C binding of sfml. I am receiving the same error as Richy19:

Code: [Select]

CMake Error at src/SFML/CMakeLists.txt:22 (find_package):
Could not find module FindSFML.cmake or a configuration file for package
SFML.

Adjust CMAKE_MODULE_PATH to find FindSFML.cmake or set SFML_DIR to the
directory containing a CMake configuration file for SFML. The file will
have one of the following names:

SFMLConfig.cmake
sfml-config.cmake
The steps I took to compile CSFML was to first compile SFML2 (latest snapshot) with CMake-Gui using "Visual Studio 9 2008".

After that I had two different outputs, sfml-build in the sfml snapshot folder and %APPDATA%/SFML. These two folders
contained solutions to build the projects for Visual Studio 2008. The one in %APPDATA% compiled successfully whilst the one
in the SFML-Build folder only succeeded with two out of 5 projects.

I can't find the SFMLConfig nor sfml-config in neither of these directories, therefore I am wondering where this cmake file i supposed to be located!

Thanks in beforehand!

[Laurent]

To install SFML correctly you must execute the "install" target. If you generated a Visual Studio solution, this is a project of the solution. The install target locates your CMake install folder and copies FindSFML.cmake in it.

If, for some reason, you don't want to execute the "install" target, you can manually copy the cmake/Modules/FindSFML.cmake to cmake_install_dir/share/Modules. cmake_install_dir is of course the directory where you installed CMake.

Thanks for you reply!

Now after further researching, I've discovered that I do have a file named "FindSFML.cmake" in the directory/folder from the snapshot in this (relative)
directory sfml/cmake/Modules/. Now the problem is, how do I inform (if this is the correct cmake file) cmake that the file is located in this directory?

I've attempted to change the SFML_DIR name/variable to both the sfml/ directory and the sfml/Modules/ directory but none of them have worked.
Any tips?

[Laurent]

Hum... did you actually read my previous answer? :|

[atomen]

Hum... did you actually read my previous answer? :|

After further research, no I did not.

Though now I have an additional problem, this is the output when I attempt to compile the C binding: (long text, scrollbars anyhow?)

Found SFML: C:/Program Files (x86)/Microsoft Visual Studio/VC/include
Configuring incomplete, errors occurred!

[Laurent]

This may be a bug in FindSFML.cmake. I'll check this as soon as I can.

[Laurent]

Should be fixed now.

[atomen]

Should be fixed now.

Thank you for fixing that!

Though I do still have one problem, when I try to compile the solution now, I receive this error (latest snapshot):

Code: [Select]

[Laurent]

The message says it all: you're tring to link CSFML 2 to SFML 1. You must of course use SFML 2.

[atomen]

The message says it all: you're tring to link CSFML 2 to SFML 1. You must of course use SFML 2.

Now, excuse me if I sound dumb, but does the latest snapshot even include SFML 1?
The PostFX class/header and source files doesn't even exists, only the shader class.

[Laurent]

Now, excuse me if I sound dumb, but does the latest snapshot even include SFML 1?

No.
But the Config.hpp file that we can see in your error message is clearly not from a recent SFML 2 revision.

How do you specify the SFML root directory? Do you use the SDMLDIR CMake variable? The SFMLDIR environment variable? Something else?

[MelancholyMechanic]

I'm also having trouble configuring CSFML. I built and installed SFML2 successfully in "C:/dev/libs/SFML" using MinGW and MSYS and the current files from GitHub. However when trying to build CSFML, I get the following error message:

Code: [Select]

CMake Error at c:/Program Files/CMake 2.8/share/cmake-2.8/Modules/FindSFML.cmake:165 (message):
  Could NOT find SFML (missing: SFML_SYSTEM_LIBRARY SFML_WINDOW_LIBRARY
  SFML_NETWORK_LIBRARY SFML_GRAPHICS_LIBRARY SFML_AUDIO_LIBRARY)
Call Stack (most recent call first):
  src/SFML/CMakeLists.txt:22 (find_package)

This is my configuration (using cmake-gui):



Did I forget to define a variable?

Btw: mingw32-make install didn't install the Find*.cmake files in the corresponding directory of my CMake installation - I had to copy them myself.

[Laurent]

Did you compile SFML first?

Btw: mingw32-make install didn't install the Find*.cmake files in the corresponding directory of my CMake installation - I had to copy them myself.

This is the expected behaviour.

[MelancholyMechanic]

Did you compile SFML first?

Yes, I have all the sfml-*-2.dll files in "C:/dev/libs/SFML/bin" and all the libsfml-*.a (without the 2 suffix - is that correct?) files in "C:/dev/libs/SFML/lib".

This is the expected behaviour.

Ah, I misinterpreted this statement then: "You must have installed SFML 2 before, and if you did it successfully, the FindSFML.cmake file should have been copied to your CMake directory."
