General / Precompiled SFML 1.6 for 64 Bit Windows

« on: November 26, 2011, 06:13:49 pm »

I just switched to Windows 64 Bit and need new compiled versions of SFML 1.6 for 64 Bit MSVC. Where can I get those? Or does anyone have them lying around?

I'd of course also like SFML 2.0 64Bit, but that is still instable and not available precompiled at all.

C / [Mac] Precompiled OpenAL in CMake

Thank you for the help. I got a precompiled SFML 1.6 to work, but not in the way I want. The reason for switching to 1.6 from 2.0 was that 1.6 comes precompiled and is labeled 'stable'.

My folder layout is this:

Code: [Select]


project/libs/SFML-1.6/include/SFML/Audio.hpp
project/libs/SFML-1.6/lib-mac/sfml-audio.framework/...
project/libs/SFML-1.6/lib-mac/sndfile.framework/...
project/libs/SFML-1.6/lib-win/sfml-audio.dll
project/libs/SFML-1.6/lib-win/sfml-audio.lib
project/libs/SFML-1.6/lib-win/libsndfile-1.dll
project/src/main.cpp


Here is my new CMakeList.txt

Code: [Select]

# SFML
set(SFML_PATH ${PROJECT_ROOT}/libs/SFML-1.6)
FIND_LIBRARY(SFML_AUDIO_LIBRARY NAMES sfml-audio sfml-audio.dll PATHS ${SFML_PATH}/lib-mac ${SFML_PATH}/lib-win DOC "SFML-audio library")
FIND_LIBRARY(SFML_SNDFILE_LIBRARY NAMES sndfile sndfile.dll PATHS ${SFML_PATH}/lib-mac ${SFML_PATH}/lib-win DOC "SFML-sndfile library")
include_directories(${SFML_PATH}/include)
set(SFML_LIBRARY ${SFML_AUDIO_LIBRARY} ${SFML_SNDFILE_LIBRARY})

...

add_executable(myapp ... )
target_link_libraries(myapp glfw ${SFML_LIBRARY} )

CMake correctly finds the library on my Mac when I compile the CMake file -
SFML_SNDFILE_LIBRARY = "/Users/username/Project/libs/SFML-1.6/lib-mac/sndfile.framework" and Compiling the project on XCode throws no linker errors.

When starting this compiled project now though, it crashes because the executable can't actually find the library/framework (Library not loaded ... image not found - exactly like this old post).

The way I got it to work was to copy all the libs to /System/Library/Frameworks - but I'd rather CMake took care of this somehow. Why doesn't it find those Frameworks when it can see the correct folder?

C / [Mac] Precompiled OpenAL in CMake

Thank you for the help Hiura.

OpenAL or libsndfile?

Both. You can see how SFML link them in src/Audio/CMakeLists.txt (I think). OpenAL is by default installed on a Mac but sndfile isn't. So you'll have to ship a copy of sndfile.framework with your application (or rebuild it and link it statically but its license might not be compatible with your application's license – you should check that out).

I was trying to avoid including too much fluff to keep things simple and one-click-compilable. I guess I might as well just use a precompiled SFML 1.6 then.

Are there any tutorials/ressources on how to create a cross-platform CMake file that uses a precompiled 1.6 and its dependencies? I guess I want to automate the step "Integrating the libraries / frameworks into your application" via CMake for OSX, Windows and Linux. I suppose FindSFML.cmake can be used for this somehow.

C / [Mac] Precompiled OpenAL in CMake

I'm trying to integrate SFML2 into my own CMake process on Mac/OSX Lion with the latest XCode. Here is my CMakeLists.txt:

Code: [Select]

# SFML
add_subdirectory(${SFML_ROOT_PATH})
include_directories(${SFML_ROOT_PATH}/include)

# MyProject
...
add_executable(myproject WIN32 MACOSX_BUNDLE ${MYPROJECT_FILES} )
target_link_libraries(myproject sfml-system sfml-window sfml-audio)

I am using static compilation.

MyProject then has a Main.cpp that includes <SFML/system.hpp> and makes the SFML timer work reliably. It is awesome and clean.
However, using <SFML/audio.hpp> compilation fails because it can't use or find some proper library (OpenAL or libsndfile?) and complains about unreferenced symbols.

Here is the error Message XCode throws at me:

Code: [Select]

To fix this on Windows, I'd probably just have to copy the needed .dlls somewhere and be done with it. But I have no idea what to do on a Mac. Do I have to tell CMake something special so that it finds the precompiled libraries you provide? I'd rather not manually copy libraries/frameworks around on my harddrive because I work with multiple Macs that are not mine and I have to keep it portable.

Thank you in advance for any help. I'm really stumped here.  :oops:
