DLL not found issue in Mac build

[aadhilkhan]

Getting this error in my MacOS mono build;

How can I fix this? Thanks!

In my case, Build Settings>PC, Mac & Linux Standalone > Architecture > "Intel 64-bit" works fine in my M1 mac and my old i-mac using Unity 2020.3.9f1.

Unfortunately I get same error messages setting "Apple silicon" or "Intel 64-bit + Apple silicon".
Even though I rebuilt StandaloneFileBrowser.bundle on Xcode of M1 mac, I cannot fix this issue now.

[krys64]

Same error here, only intel 64-bit works

[hippogamesunity]

The same here with Mac M1 =(

[hippogamesunity]

@gkngkc hi! btw do you still support this project or it's abandoned?

[acgourley]

Same issue here, a pure intel64 build works but if it's built for silicon and intel64 the runtime will not find the dll.

[acgourley]

I solved this by building a universal bundle. To do this, I opened the StandaloneFileBrowser.xcodeproj/project.pbxproj and modified
ARCHS = "$(ARCHS_STANDARD_32_64_BIT)";
to
ARCHS = "$(ARCHS_STANDARD)";

and I removed VALID_ARCHS = x86_64; which when set made the .bundle created not include the arm64 slice.

Finally I confirmed with lipo -info StandaloneFileBrowser output x86_64 arm64 and replaced it into the unity project.

[davidmfinol]

I solved this by building a universal bundle. To do this, I opened the StandaloneFileBrowser.xcproject and modified

@acgourley

Where is this StandaloneFileBrowser.xcproject file? I'm not finding this file name in this repo.

EDIT: I take it that all we need is an updated version of the .bundle? Is there any way you could share the .bundle that you built?

[acgourley]

Ah typo in that filename, it's this one: https://github.com/gkngkc/UnityStandaloneFileBrowser/blob/master/Plugins/MacOS/StandaloneFileBrowser/StandaloneFileBrowser.xcodeproj/project.pbxproj

[davidmfinol]

Thank you, I got it working!

[hippogamesunity]

@davidmfinol Hello! Can you share your updated bundle please?

[davidmfinol]

@davidmfinol Hello! Can you share your updated bundle please?

Sure, you can find the bundle I created here: https://github.com/finol-digital/Card-Game-Simulator/tree/develop/Assets%2FStandaloneFileBrowser%2FPlugins%2FStandaloneFileBrowser.bundle

[hippogamesunity]

@davidmfinol Many thanks! I was able to make it work. One thing you should note that we need to select StandaloneFileBrowser.bundle and choose 'Any CPU' option (it looks like it's set to 'Intel 64-bit' in your project).

[hippogamesunity]

@davidmfinol btw did you manage to also fix this issue?
#101

[davidmfinol]

@hippogamesunity
Thanks for pointing out the cpu option!
As for the other issue, I don't know if I "fixed" it, but at least I don't seem to be having that issue with my project.

[JudahMantell]

For posterity's sake, here's the current link to @davidmfinol 's repo that has the functioning bundle file.
I just replaced the current .bundle file with this one and it works great on my M1 MacBook Air.

Thanks!

@SceneForgeStudio Hi! I can confirm this works on M1 if built x64/silicon, but doesn't work on an old Mac with Core i5.

@SceneForgeStudio Hi! I can confirm this works on M1 if built x64/silicon, but doesn't work on an old Mac with Core i5.

Interesting, so if I build just for regular x64/Intel then it won't work, only if it's a universal build?
I haven't tested an Intel-Only build, as I only need to publish for M1 (and universal during my app's beta period).

[hippogamesunity]

Tested x64 architecture only + Core i5, it doesn't work (missed DLL).

[JudahMantell]

In that case you'll have to use the older non-M1 dll. You can probably use both and just change which CPU each one is for in the inspector.

[hippogamesunity]

I'm not sure if we can include both original and fixed bundles.

[hippogamesunity]

We need a true mac dev as there is source code available) I'm not, unfortunately.

@acgourley thank you so much!!
Now work in mac m2 pro!!

If anyone need it, these are the precise steps I followed:

1. In the UnityStandaloneFileBrowser folder, go to Plugin -> MacOS -> StandaloneFileBrowser
2. Show package contents of StandaloneFileBrowser.xcodeproj
3. Open the project.pbxproj file with Xcode
4. Change the line ARCHS = "$(ARCHS_STANDARD_32_64_BIT)"; to ARCHS = "$(ARCHS_STANDARD)";
5. Remove the line VALID_ARCHS = x86_64;
6. Save the file and close Xcode
7. Go back to the Plugin -> MacOS -> StandaloneFileBrowser folder
8. Open StandaloneFileBrowser.xcodeproj with Xcode
9. Perform the build. A StandaloneFileBrowser.bundle file will be created
10. Go to the folder where the file was just created (you can find it in Xcode by going to Product -> show build folder in finder)
11. Copy the StandaloneFileBrowser.bundle file
12. Replace the existing file in the /StandaloneFileBrowser/Plugins/folder

If you had already uploaded the asset to unity, make sure you re-import it after replacing the bundle file, before continuing with the project

[hippogamesunity]

This project is abandoned. The asset has a few critical bugs on Mac, like app crashes when you press Cancel in File Picker.
I've purchased another asset and it works fine https://assetstore.unity.com/packages/tools/utilities/file-browser-pro-98713

Would you be able to upload/send your latest bundle file for us to use? It would be super helpful.
Thanks!

Sure! Here is the plugin with the added compatibility:

UnityStandaloneFileBrowser_arm64.zip

Unfortunately, some bugs still persist as mentioned by @hippogamesunity, but in any case, with this upgrade the system file browser is correctly loaded in macos. Therefore, in my opinion, this free plugin remains a valid alternative to other paid plugins.
