Cannot run on M1 Mac (ARM games)

[某10]

Game: The Stanley Parable: Ultra Deluxe
Hardware: MacBook Air M1

I use libdoorstop.dylib compiled by github action.
It seems can be loaded, but it cannot hook any methods.

I'm working on x86_64 mac now. It has the same problem as m1 mac.

At present, plthook_handle_by_name can obtain the address of UnityPlayer.dylib, but plthook_open_by_address not working.

I tried to print its error, i got: Cannot find address: 0x207b47100
It seems that dladdr cannot get info from this address,

UnityDoorstop/src/nix/entrypoint.c

Lines 75 to 86 in 2441a60

 void *unity_player = plthook_handle_by_name("UnityPlayer"); 
  
 // TODO: Chekc if this still works on macOS 
 if (unity_player && plthook_open_by_address(&hook, unity_player) == 0) { 
     LOG("Found UnityPlayer, hooking into it instead"); 
 } else if (plthook_open(&hook, NULL) != 0) { 
     LOG("Failed to open current process PLT! Cannot run Doorstop! " 
         "Error: " 
         "%s\n", 
         plthook_error()); 
     return; 
 } 

UnityDoorstop/src/nix/plthook/plthook_osx.c

Lines 192 to 201 in 2441a60

 int plthook_open_by_address(plthook_t **plthook_out, void *address) { 
     Dl_info dlinfo; 
     uint32_t idx = 0; 
     uint32_t cnt = _dyld_image_count(); 
  
     if (!dladdr(address, &dlinfo)) { 
         *plthook_out = NULL; 
         set_errmsg("Cannot find address: %p", address); 
         return PLTHOOK_FILE_NOT_FOUND; 
     } 

Update:

I replaced plthook_open_by_address with plthook_open, it will working.

#27 should fix it now. Feel free to reopen if the issue still persists.

Still seems to be an Issue for me. Same hardware as mo10, But i'm trying to run on Subnautica.
