### Writing plugins in other languages ### Writing plugins in C++
When writing plugins with C++, game headers must be surroundined with `extern "C"`, i.e. When including game headers, they must be surrounded with `extern "C"`, i.e.
```C ```C
extern "C" { extern "C" {
#include "src/Chat.h" #include "src/Chat.h"

Otherwise you will get obscure `Undefined reference` errors when compiling. Otherwise you will get obscure `Undefined reference` errors when compiling.
Exported plugin functions must be surrounded with `extern "C"`, i.e.
```C
extern "C" {
EXPORT int Plugin_ApiVersion = 1;
EXPORT struct IGameComponent Plugin_Component = { TestPlugin_Init };
}
```
Otherwise your plugin will not load. (you'll see `error getting plugin version` in-game)
