OS X library missing

[Byteron]

Hello there!
It seems there is a problem on OS X platforms. We get this error when trying to run our project:

I see, apparently there is no library for OS X in the first place.
Would it be possible to add it?

[Beliar83]

Heya, I do not have access to OS X myself, and the build service I use, appveyor, does also not have support for that, I think.

I would be happy to add the libraries if I had them.

[Byteron]

in your godot-yaml repo there seems to be this part in the Sconstruct file.

if platform == "osx":
    env.Append(CCFLAGS = ['-g','-O3', '-arch', 'x86_64', '-std=c++14'])
    env.Append(LINKFLAGS = ['-arch', 'x86_64'])
    env.Append(LIBS=["libyaml-cpp"])
final_lib_path = final_lib_path + 'osx/'

I thought it indicated that building for osx is possible. But then again, I have no idea how scons works.

[Beliar83]

Yes, that is true, but as far as I know this will not work unless one has an OSX (virtual) machine that can build that. And as said, appveyor has, as far as I know, no images for OSX. I will try to check if I can find a build service for that in the next days. I would also take suggestions, if you know one.

[Byteron]

So if I had an os x system, I could build it?

[Beliar83]

Yes, if you have the tools (compiler, scons) setup. You can look up the details here: https://docs.godotengine.org/en/3.0/tutorials/plugins/gdnative/gdnative-cpp-example.html#compiling-our-plugin

Also check the readme in the godot-yaml repo, even though it is probably not explaining much.

[Beliar83]

Interesting, I will take a look at that, I may be able to do that on the linux image in appveyor. Thanks.

[Beliar83]

I have uploaded the osx library. I will update the info of the godot asset library shortly, which then needs to be approved by someone from godot.

Please reopen if it does not work with the added library.

[critcap]

The osx library doesnt seemt to work with godot 3.2.1 atleast. Getting the exact same error as the original poster.

[Beliar83]

@critcap Can you confirm whether the file "addons\godot-yaml\osx\libgodotyaml.dylib" exists?

There is also a possibility that the current files do not work with godot 3.2.1, as they were made for godot 3.1 and I have not worked on this since then.

[critcap]

Yes, its in the osx folder. I also tried to move it to other locations and changing the path but nothing helped.
It might be an incompatibility with godot 3.2.1, are there any plans to update?

[Beliar83]

@critcap I will look into it. Hopefully not much changed in terms of native.

[Beliar83]

@critcap I have uploaded a version for 3.2 and submitted a new asset. You can either wait for someone to approve it, or download the latest release from here.

[critcap]

still doesnt work for me on osx, same error as before. Are there any possbile prerequisites im missing?
My error message:

[Beliar83]

There should be no prerequisites. I am using cross compiling on linux, though, maybe it is just not working. I don't have osx myself, though, so I can't really test it myself.

I remember reading that travis has added building on osx recently, though, I will take a look at that.

[Beliar83]

Ah, actually, that is why I am already using travis for osx builds, so nothing to change there.

[Beliar83]

@critcap It is possible, though, that you may need to install the "yaml-cpp" package, not sure if it is linked dynamcially or statically.

[C45tr0]

I am having the same issue, except on windows. Same error except instead of the osx path its "{...}/addons/godot-yaml/win64/libgodotyaml.dll".

I tried building the yaml-cpp package. Not sure if I installed it or not(might be the issue, still digging into it), but still getting the same errors.

I tried the asset store, then tried the files in this repo in case they were still outdated on the asset store.

[Beliar83]

I can't reproduce that here. I am going to setup up VM to see if I can reproduce them there.

[Beliar83]

@C45tr0 I cannot reproduce that even on a fresh windows (10) install.
Is it possible, that windows flagged the DLL files as insecure - which may happen for downloaded files - and you need to set them as secure? Otherwise I am not sure what the problem can be.

[C45tr0]

Thanks for looking.

I looked at permissions and didn't see anything off. Will keep trying some things tonight.

[shayneoneill]

I just noticed when installing it, it tries to skip installing the dll/dylib/etc. Make sure you actually tick them if installing from app store

edit: Nope that dont fix it
