# cpp_bindings

C++ bindings for the Godot script API
# Creating a GDNative library (Linux)
Create a directory named `SimpleLibrary` with subdirectories `lib, src`
Getting latest `cpp_bindings` and `godot_headers`
Getting latest `godot-cpp` and `godot_headers`
```
$ cd SimpleLibrary
$ git clone https://github.com/GodotNativeTools/cpp_bindings
$ git clone https://github.com/GodotNativeTools/godot-cpp
$ git clone https://github.com/GodotNativeTools/godot_headers
```
right now our directory structure should look like this
right now our directory structure should look like this:
```
[SimpleLibrary]
├── cpp_bindings/
├── godot_headers/
├── lib/
└── src/
godot-cpp
godot_headers
SimpleLibrary
├── lib/
└── src/
```
Now to generate cpp bindings
```
$ cd cpp_bindings
```
Edit `SConstruct` file and assign your godot executable path at line:7 `godot_bin_path = "../godot_fork/bin/"`,
Building cpp_bindings
```
$ scons godotbinpath="../godot_fork/bin/godot_binary" headers="../godot_headers/" p=linux generate_bindings=yes
$ cd godot-cpp
$ scons godotbinpath="../godot_fork/bin/godot_binary" p=linux
$ cd ..
```
resulting libraries will be placed under `bin/` and the generated headers will be placed under `include/*`
**Note:**
> `generate_bindings=yes` is used to generate C++ bindings (`godot_api.json` - Godot API)
> `regenerate_bindings=yes` is used to force regenerating C++ bindings (`godot_api.json` - Godot API)
> Include `use_llvm=yes` for using clang++
Copy binding libraries into the `SimpleLibrary/lib` folder
```
$ cd ..
$ cp cpp_bindings/bin/libgodot_cpp_bindings.a lib/
```
And our directory structure will be
```

This creates the file `libtest.so` in your `SimpleLibrary/lib` directory. For windows you need to find out what compiler flags need to be used.
