Alright then, so, when comes to the problem of scope I will not be using those SFML resources in Sigleton classes. Thanks  .

Audio / [SOLVED] Problem with Singletons

« on: May 09, 2023, 12:06:30 am »

There is some problem if I call the destructor of a sf::SoundBuffer before it reaches the normal end of scope!? because I am using a singleton class to store global sounds that can be used for any class in the application, but, the aplication is big enough to require a more smart loading instead load everything at the beginning of the application.

Every time I free those sound buffers by just removing its unique_ptr from a map, when the application reaches the end I've got: 'malloc(): unsorted double linked list corrupted', maybe there is some restriction because the sf::SoundFileFactory that keeps some global info, that will properly RAII at the end of application only!?

For instance, I've only loaded the buffers and freed them. I did not create any sf::Sound or play it, just loaded and freed it by removing the unique_ptr from the map using its 'key' on the 'erase' method.

Graphics / Re: Linker error with libfreetype

Solved.

I simply remove manually this 'libfreetype.a' file from '/usr/local/lib' and do this basic process of compiling with cmake as I've described above. My system already has the 'libfreetype-dev'.

I don't know how it appears but, that is it.

Thanks for your attention eXpl0it3r.

How did you get freetype? It looks like a static library, did you build it yourself?

I've downloaded it at: https://www.sfml-dev.org/download/sfml/2.5.1/

This is the stable version, scroll down it says: All | source code

1. I create a folder in the root dir called: DEBUG
2. I enter that folder with the terminal.
3. Then call: cmake -DCMAKE_BUILD_TYPE=Debug ..
4. Then: make

Where I get those message errors when it tries to compile the sfml-graphics-d module. In the source code there is a folder called 'extlibs' but I think is for OS Windows, maybe somehow it compiles some static libraries from that? or uses it!? Because previously I've tried to build statically and it works, then I installed with 'make install'.

Graphics / Linker error with libfreetype [SOLVED]

I'm having some trouble when trying to compile the source code using cmake. I'm on Unbuntu 22.04 amd64, and when it tries to link the libsfml-graphics.so I get this error message:

As you can see the other modules build fine.
