Linux build error (Ubuntu 22.04.5)

[HoJo215]

I haven't build this in a while.. last time was when it was at svn.code.sf.net

This is where the error starts.. Seems like it's not liking something in the Rules.inc file:

Src/OSD/SDL/Main.cpp: In function ‘int main(int, char**)’: Src/OSD/SDL/Main.cpp:2095:15: error: ‘SDL_HINT_WINDOWS_DPI_AWARENESS’ was not declared in this scope 2095 | SDL_SetHint(SDL_HINT_WINDOWS_DPI_AWARENESS, "system"); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Src/OSD/SDL/Main.cpp: At global scope: Src/OSD/SDL/Main.cpp:209:24: warning: ‘void DebugCallback(GLenum, GLenum, GLuint, GLenum, GLsizei, const GLchar*, const void*)’ defined but not used [-Wunused-function] 209 | static void GLAPIENTRY DebugCallback(GLenum source, GLenum type, GLuint id, GLenum severity, GLsizei length, const GLchar* message, const void* userParam) | ^~~~~~~~~~~~~ make: *** [Makefiles/Rules.inc:345: obj/Main.o] Error 1

Might need updated sdl

Might need updated sdl

This is a fresh install. Followed the install dependencies:
sudo apt install libsdl2-dev && sudo apt install libsdl2-net-dev

libsdl2-dev is already the newest version (2.0.20+dfsg-2ubuntu1.22.04.1)
libsdl2-net-dev is already the newest version (2.0.1+dfsg1-7)

edit:

So I have it building without the NET_BOARD=1 flag
With the NET_BOARD=1 flag I receive this error:

Src/OSD/SDL/SDLIncludes.h:44:10: fatal error: SDL_net.h: No such file or directory
   44 | #include <SDL_net.h>
      |          ^~~~~~~~~~~
compilation terminated.
make: *** [Makefiles/Rules.inc:345: obj/TCPReceive.o] Error 1

libsdl2-net-dev is installed.. Any ideas?

How are you building it? Also, your version of SDL2 looks a bit older, although I forget how I installed mine. Try the following command and see what your include path is set to:

(base) bart@Technodrome-U:~/projects/Supermodel$ sdl2-config --cflags
-I/usr/include/SDL2 -D_REENTRANT

My version information:

We may need to uninstall the packages you have (especially if they came preinstalled) and simply reinstall them. But I'd like to first see where sdl2-config thinks the files are. Because if the include path is invalid, that would obviously be a big problem.

Sorry for the late reply. This is what I have:

This is the error I receive now:
