Can't generate bindings about godot-cpp HOT 18 CLOSED

Okay, should now build fine!

from godot-cpp.

There are a lot of people excited about GDNative.Thanks for your efforts karroffel! :)

from godot-cpp.

Interesting, I can now reproduce. This is an upstream error though, I'll see if I can make a patch for Godot.

Looking into it ;)

from godot-cpp.

@gtsiam just opened a PR here

So, if that really is all there is to it, could you please hurry with the fix?

But damn, chill 😄 These bindings are still subject to change, so don't really rely on them. Nice to see you needing them though 😄

What are you using them for though? Just interested to hear ^^

from godot-cpp.

Nice, thanks! I just want to experiment with a couple of procedural generation ideas, previously limited by GDScript's performance. Did not mean for it to look like I was so dependent on the bindings that I needed a fix right there and then (at least, not yet 😄). But hey, no harm done!

from godot-cpp.

@JimmyJames707 Huge patch incoming, should fix everything :)

from godot-cpp.

Did you download a tool build?
Are you on Linux?

from godot-cpp.

I downloaded this one:
http://fixnum.org/godot/17_05_19__20_21_33/tools/godot.x11.tools.64

I am on Manjaro, which is Arch.

Are you using one from the above list? If so perhaps I should use the date you are using.

from godot-cpp.

I'm compiling Godot myself - always.

So this might be a problem with an outdated version of fixnum builds

from godot-cpp.

Okay I just built Godot on this machine. It gets a lot further, but I have the same problem with this command:

from godot-cpp.

Any ideas what might be wrong? It has a problem with ColorRamp.hpp. Is there a file missing that is needed to handle that?

from godot-cpp.

That's really weird. It should generate that file. It compiles for me, looks like your api.json generated from Godot is weird or something.

Is there the file include/ColorRamp.hpp for you?

from godot-cpp.

Is there the file include/ColorRamp.hpp for you?

No, there is no such file.

cpp_bindings/include/core has files in it. cpp_bindings/include/ is empty.

from godot-cpp.

Oops, I must have deleted it and downloaded it again.

I just ran those commands again. The include directory has files in it, but there is no ColorRamp.hpp. There are 412 files in it.

from godot-cpp.

From what I can gather, the problem seems to be with the Gradient class in Godot not deciding whether it wants to be called Gradient or ColorRamp. So, if that really is all there is to it, could you please hurry with the fix? Because I cant use the c++ bindings until then, and I imagine many others have the same problem (ie everyone at this point in time) - so... Bump...

from godot-cpp.

Okay I had time to try again. I downloaded and built Godot + downloaded latest GDNative, but it gets stuck on the same command. Oh well. lol
