statically linking SDL2 on Linux and macOS "like on Windows"

i had made a game on C using SDL2, SDL2_image, SDL2_mixer and SDL2_ttf libraries installed on Linux (Ubuntu) by sudo apt-get install libsdl2-dev (for example), and i wanted to improve it so it will be compileable on Linux, macOS and Windows (with MinGW) without pre-installing required libraries.

i downloaded libraries' sourse code from SDL Github (for example SDL2) and compiled them on Ubuntu and macOS using ../configure --prefix=/some/path; make; make install in "build" folder that i had created in folder with source code after unzipping downloaded archive. as for Windows, i downloaded SDL2-devel-2.32.0-mingw.zip (as for SDL2) from the same source and just extracted "i686-w64-mingw32" folder from it.

after that i uploaded obtained folders (i686-w64-mingw32 for Windows and that plased in /some/path from --prefix for Linux and macOS) on my game's Github repository renamed them like "SDL2", "SDL2_image", etc. respectively and at the end deleted that folders where i compiled libraries.

so the structure of my project is something like that:

• game_dir
  • inc/header.h
  • resources
    • frameworks
      • linux
        • SDL2
          • bin/sdl-config
          • include/SDL2/.h files
          • lib
            • cmake/SDL2
              • sdl2-config.cmake
              • sdl2-config-version.cmake
            • pkgconfig/sdl2.pc
            • libSDL2.a libSDL2.la
            • libSDL2_test.a libSDL2_test.la
            • libSDL2-2.0.so.0.3200.0
            • libSDL2main.a libSDL2main.la
          • share/aclocal/sdl2.m4
        • SDL2_image this three have
        • SDL2_mixer "include" and "lib" folders
        • SDL2_ttf (same as in "SDL2" folder)
      • macos the same structure with "linux" folder (but instead .so files there are .dylib files)
      • windows there are also bin/.dll files and .dll.a files in "lib"
    • folders with images, music, etc.
  • src/.c files
  • Makefile
  • .dll files for Windows

then i cloned my repository and tried to compile the code with such Makefile:

executable:=mygame

inc_dir:=inc
src_dir:=src
obj_dir:=obj
lib_dir:=resources/frameworks/

src_files:=$(wildcard $(src_dir)/*.c)
obj_files:=$(src_files:$(src_dir)/%.c=$(obj_dir)/%.o)

compiler:=gcc
cc_flags:=-std=c11 -Wall -Wextra -Werror -Wpedantic
inc_flags=-I$(inc_dir) \
    -I$(lib_dir)/SDL2/include/SDL2 \
    -I$(lib_dir)/SDL2_image/include/SDL2 \
    -I$(lib_dir)/SDL2_mixer/include/SDL2 \
    -I$(lib_dir)/SDL2_ttf/include/SDL2
lib_flags=-L$(lib_dir)/SDL2/lib -lSDL2main -lSDL2 \
    -L$(lib_dir)/SDL2_image/lib -lSDL2_image \
    -L$(lib_dir)/SDL2_mixer/lib -lSDL2_mixer \
    -L$(lib_dir)/SDL2_ttf/lib -lSDL2_ttf

newdir:=mkdir
removedir:=rm
removefile:=rm

ifeq ($(OS),Windows_NT)
    lib_dir:=$(lib_dir)windows
    lib_flags:=$(lib_flags) -lmingw32 -mwindows
    removedir:=rmdir /s /q
    removefile:=del
else
    newdir:=mkdir -p
    removedir:=rm -rf
    removefile:=rm -f
    ifeq ($(shell uname),Darwin)
        lib_dir:=$(lib_dir)macos
    else
        lib_dir:=$(lib_dir)linux
    endif
endif

all: $(executable)

$(executable): $(obj_files)
    $(compiler) $(cc_flags) $^ -o $@ $(inc_flags) $(lib_flags)

$(obj_dir)/%.o: $(src_dir)/%.c | $(obj_dir)
    $(compiler) $(cc_flags) -c $< -o $@ $(inc_flags)

$(obj_dir):
    $(newdir) $(obj_dir)

clean:
    $(removedir) $(obj_dir)

uninstall: clean
    $(removefile) $(executable)

reinstall: uninstall all

.PHONY: all clean uninstall reinstall

it works perfectly on Windows, but on Linux and macOS when it comes to compile executable file, such errors occur:

• on Linux:

/usr/bin/ld: resources/frameworks/linux/SDL2/lib/libSDL2.a(SDL_stdlib.o): In function «SDL_fmod_REAL»:
/path/to/directory/where/i/compiled/library/(that_does_not_exist_now)/src/stdlib/SDL_stdlib.c:279:(.text+0x35d): undefined reference to `fmod'
...
collect2: error: ld returned 1 exit status
make: *** [Makefile:46: mygame] Error 1

• on macOS:

Undefined symbols for architecture x86_64:
    "_CFArrayAppendValue", referenced from:
        _GetDisplayMode in libSDL2.a(SDL_cocoamodes.o)
    ...
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [mygame] Error 1

there are a lot of errors on every of that os, they just have the same syntax so i gave only one of them for each os for example. also problems are not only with SDL2 but with other libraries too.

actually, when i use frameworks (that things like SDL2.framework) on macOS (of cource with a bit different Makefile), it works too, but i want everything to be "in one style" with "include" and "lib" folders for each os. can it be possible?

i thought adding -static or -Wl,-Bstatic to lib_flags or using -l: instead of -l or specifying the path to library like for example $(lib_dir)/SDL2/lib/libSDL2.a can solve that problems, but it still doesn't work.

maybe i need to compile libraries with some extra flags or upload dependency libraries like freetype2 for SDL2_ttf or just somehow improve my Makefile?

thank you in advance!

versions of operating systems on which i worked: Ubuntu 24.04, macOS 11.1.0 installed on VirtualBox.
