How do you properly export the example project? #5

Hello. I'm back again, this time with a non-duplicate issue. I now know how to check the closed issues before submitting my own (lol).

I'm not aware of any kind of special procedure for exporting with GDNative, so I simply used the traditional 'Project > Export' method in the Godot editor. The project works as intended on my computer, but when I send it to my friend's they get this error instead:

ERROR: Can't open dynamic library: addons/example/gdnative-example.dll, error: Error 126: The specified module could not be found.
.
   at: (platform/windows/os_windows.cpp:2353)
ERROR: No valid library handle, can't get symbol from GDNative object
   at: get_symbol (modules/gdnative/gdnative.cpp:510)
ERROR: No nativescript_init in "res://addons/example/gdnative-example.dll" found
   at: init_library (modules/gdnative/nativescript/nativescript.cpp:1510)
ERROR: Error opening file 'res://icon.png'.
   at: load_image (core/io/image_loader.cpp:55)
SCRIPT ERROR: Attempt to call function 'new' in base 'NativeScript' on a null instance.
          at: _ready (res://example.gdc:5)

Despite what the error says, the .dll is clearly in that directory. I found a similar issue and what I think is happening is the .dll isn't able to load because of dependencies available on my machine, but not on others'. Here's a list of the file's dependencies:

MSVCP140D.dll
VCRUNTIME140D.dll
VCRUNTIME140_1D.dll
ucrtbased.dll
KERNEL32.dll

I saw two other similar issues, but I'm not familiar enough with VS or CMake to know out how to configure these so-called 'flags'. I assume I have to modify either 'CMakeLists.txt' or 'CMakeCache.txt', but I'm not exactly clear on what changes I'm supposed to make.

One of the issues suggested building in release mode, but when I tried that I received a few hundred errors like this one:

godot-cpp.windows.debug.64.lib(String.obj) : error LNK2038: mismatch detected for '_ITERATOR_DEBUG_LEVEL': value '2' doesn't match value '0' in Godot.obj

I've been trying to figure this out myself for a few days, but I just feel lost so now I'm asking for help again. I'm sure I'm just missing something very simple like last time.

Looks like you compiled the dll in debug mode. You need to compile it in release mode.

Hello, I have the same problem, my .dll not working on a friends computer. I've tried building it in RELEASE mode but I always get a bunch of errors just like DrBoontis does.

Has anyone found a solution to this?
