sdl | Subtree split of the Railt SDL component

I have an executable that by default uses EGL and SDL 1.2 to handle graphics and user input respectively. Using LD_PRELOAD, I have replaced both with GLFW.

This works normally unless the user has installed the Wayland version of GLFW, which depends on EGL itself. Because all the EGL calls are either stubbed to do nothing or call GLFW equivalents, it doesn't work (ie. eglSwapBuffers calls glfwSwapBuffers which calls eglSwapBuffers and so on). I can't remove the EGL stubs because then it would call both EGL and GLFW and the main executable is closed-source so I can't modify that.

Is there any way to make LD_PRELOAD affect the main executable but not GLFW? Or any other solution to obtain the same effect?

I made a simplified example to demonstrate the problem.

Main Executable:

I've looked at a lot of solutions for this problem but none have worked

i coded this.

I am trying to exit the program when the escape key is pressed. I am having some trouble doing that.

When I take out the door() line it works;

I created a shortcut in a Windows PC with a target path of:

C:\Users\b\Desktop\New Text Document.txt

Then I copied the shortcut to another PC with a different user name, and I want to retrieve the original target path.

If you open the shortcut file with a text editor, you can see the original path is preserved, so the goal is definitely possible.

The following code does not work, despite the presence of SLGP_RAWPATH. It outputs:

C:\Users\a\Desktop\New Text Document.txt

It is changing the user folder name to the one associated with the running program.

I understand that the problem is not about environment variables, because no environment variable name can be seen in the file. But I can't find any documentation about this auto-relocation behavior.

I'm using a schema interceptor to configure my schema. It's a multi-tenant application, so I build the schema according to the tenant's configuration. I'm mapping that configuration to SDL language (schema-first approach) and then I add it to the schema builder (schemaBuilder.AddDocumentFromString(...)).

As said on the documentation (here), "Schema-first does currently not support filtering!". But that is the only approach I can use right now, so I'm trying to find a workaround.

What I've tried:

Manually create the input filter types and add the filtering to the server (something like this):

I made a template folder for SDL2 projects. I followed this tutorial from Lazy Foo: http://lazyfoo.net/tutorials/SDL/01_hello_SDL/windows/mingw/index.php to create my makefile.

My makefile:

There is a problem with rendering target switch on Raspberry Pi. SDL_SetRenderTarget() hangs if multiple renderer switch occurs.

This is a working code that prints milliseconds since application starts before and after a rendering target switch:
