SFML static build: Unresolved externals from sf::priv namespace

[LeksiDor]

Hello!
I've managed to clone SFML git repo, then build with CMake and compile together with examples. All examples are working, no errors were detected. Then, I wrote a simple HelloWorld project using locally-built SFML lib, but when I compile it, I get 10 unresolved externals. All of them refer to system-specific functions implemented in sf::priv namespace. Could you help me to fix it? I have no clues what's wrong...

My environment: Windows 10, CMake 3.14.1, MSVC 16 2019.
My folder structure:
    * cloned SFML project: D:\Work\SFML ;
    * HelloWorld project: D:\Work\TestSFML ;
    * content of TestSFML folder: CMakeLists.txt, Initialize3rdparty.sh (copies SFML lib and headers), src\HelloWorld\main.cpp .

Thanks!

That's not how you're supposed to use SFML with CMake. See this topic: https://en.sfml-dev.org/forums/index.php?topic=24070.0

[LeksiDor]

Ok, I have downloaded SFML binaries (2.5.1 x64 VC15), and changed CMakeLists.txt correspondingly. Now everything works.

That's my new CMakeListst.txt:

(click to show/hide)

cmake_minimum_required ( VERSION 3.1 )
project (TestSFML)
set ( SFML_STATIC_LIBRARIES TRUE )
set ( SFML_DIR "../SFML-2.5.1/lib/cmake/SFML" )
find_package ( SFML COMPONENTS graphics audio REQUIRED )
add_executable ( HelloWorld src/HelloWorld/main.cpp )
target_link_libraries ( HelloWorld sfml-graphics sfml-audio )

However, how can I use SFML lib that is built from currrent git repo?

Also, how can I have Debug and Release versions of SFML for my HelloWorld Debug and Release builds correspondingly?

Thanks!

[Laurent]

However, how can I use SFML lib that is built from currrent git repo?

The exact same way. Once you've built the "install" target, you have a SFML folder that is similar to the official releases.

Also, how can I have Debug and Release versions of SFML for my HelloWorld Debug and Release builds correspondingly?

That's handled by the SFML config file automatically, you don't have to care about it.

[LeksiDor]

I've modified CMakeLists.txt in my HelloWorld project once again, and that's how it looks now:

(click to show/hide)

cmake_minimum_required ( VERSION 3.1 )
project (TestSFML)
set ( SFML_STATIC_LIBRARIES TRUE )
set ( SFML_DIR "../SFML/build" )
find_package ( SFML COMPONENTS graphics audio REQUIRED )
add_executable ( HelloWorld src/HelloWorld/main.cpp )
target_link_libraries ( HelloWorld sfml-graphics sfml-audio )

Value SFML_DIR now points to locally built Git repo.
But CMake refuses to build HelloWorld project, and shows this output:

CMake Error at D:/Work/SFML/build/SFMLConfig.cmake:139 (message):
  SFML found but some of its dependencies are missing ( FreeType OpenAL
  VorbisFile VorbisEnc Vorbis Ogg FLAC)
Call Stack (most recent call first):
  CMakeLists.txt:5 (find_package)


CMake Error at CMakeLists.txt:5 (find_package):
  Found package configuration file:

    D:/Work/TestSFML/../SFML/build/SFMLConfig.cmake

  but it set SFML_FOUND to FALSE so package "SFML" is considered to be NOT
  FOUND.


Configuring incomplete, errors occurred!
See also "D:/Work/TestSFML/build/CMakeFiles/CMakeOutput.log".

Any guesses what should I change now?

Thanks!

[Laurent]

Can you describe what you did (how you built SFML) in detail?

[LeksiDor]

1. Open Git bash in "D:\Work". Run "git clone https://github.com/SFML/SFML.git".
2. Open CMake GUI and run with parameters as on screenshot (see "cmake.png" attached).
3. Open MSVC solution. Compile all, in both Debug and Release.
4. Run examples. Everything is fine.
5. Create folder "D:\Work\TestSFML". It now contains "TestSFML\CMakeLists.txt" and "TestSFML\src\HelloWorld\main.cpp".
6. Run CMake with Source "D:\Work\TestSFML" and Build "D:\Work\TestSFML\build", and get mentioned errors.

[Laurent]

So you didn't compile the INSTALL target?

Once you've built the "install" target, you have a SFML folder that is similar to the official releases.

[LeksiDor]

I've just ran INSTALL, and then copied resulting SFML folder in "C:\Program Files (x86)\SFML" to the proper location in my HelloWorld. Then, run CMake, and got the same CMake errors ("dependencies are missing").

Then, I just manually copied missing libs (flac.lib, freetype.lib, ogg.lib, openal32.lib, vorbis.lib, vorbisenc.lib, vorbisfile.lib), and put them in "SFML\lib" folder.

Now everything works.

Thank you very much for time and effort!

[Laurent]

You correctly changed SFML_DIR to point to the install folder instead of the build folder, right?

You shouldn't have to copy anything manually, as I said, the INSTALL target produces a release similar to what you can download on the website and thus should work out of the box.
