# Creating a GDNative library (Linux)

Create a directory named `SimpleLibrary` with subdirectories `lib, src`

Getting latest `cpp_bindings` 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

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/
|

```

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.
