Change to the path where the actual <mark style="color:orange;">libProudNetClient.a</mark> is located, and choose between LLVM and GNU. If you have a directory structure like the one above, it should look like the screenshot.

1-7. To check, after building ChatIOS, you can run ChatServer on Windows to check for ChatIOS connectivity.

{% hint style="danger" %}
**Notes on using ProudNet in Xcode**\
※  Add <mark style="color:orange;">libiconv.dylib</mark>, a library built in Xcode.\
※ It is not available in m-files, so you need to change the extension to mm-files.\
※ Add <mark style="color:orange;">#include \<new></mark> to all mm files. In Xcode, STLs cannot be declared in header files.
{% endhint %}

## 2. Resolving errors

### - Link error with duplicate symbol when using the <mark style="color:orange;">-all\_load -Objc</mark> option

If <mark style="color:orange;">COCOs2d-x</mark>, a link error related to duplicate symbol, occurs when using the <mark style="color:orange;">-all\_load -Objc</mark> option, use <mark style="color:orange;">-force\_load</mark> instead of <mark style="color:orange;">-all\_load -Objc</mark> in <mark style="color:orange;">Other Linker Flags</mark>.

<figure><img src="/files/caxS0lo0F8Ib5HJcVMeI" alt=""><figcaption><p>Example of using the -force_load option</p></figcaption></figure>

To match the path, adjust the path to <mark style="color:orange;">PIDL.exe</mark>. If the directory structure is as above, please modify it as follows. <mark style="color:orange;">mono ../../util/PIDL.exe ../ChatCommon/\* -outdir ./ChatIOS/</mark>
