Fatal error: cannot load shared library dllsdl2_stubs

[idimension18]

Hi, I am on manjaro (arch linux base distro) I tried to compile a game with ocamlc + ocamlfind and it works. But when I run the executable I get the error : Fatal error: cannot load shared library dllsdl2_stubs Reason: /home/idimension/.opam/default/lib/stublibs/dllsdl2_stubs.so: undefined symbol: SDL_WriteBE32

SDL2 version : 2.26.5 OCaml version : 4.14.0

If you don't need this function (this is probably the case), just remove it from the sources. Here is the patch:

Recent versions of ocaml provide an equivalent function:

String.get_int32_be : string -> int -> int32

Please confirm:

git apply patch
cd src
cp Makefile.config.unix Makefile.config
make gen
make dep
make opt byte
cd ..
opam install .

The issue persists.
