Game SDK: undefined reference to GLIBC_2.27 when compiling Linux in Unreal Engine

[Zaratusa]

Description

Hi,

I'm using the Game SDK 3.2.1 on Linux in Unreal Engine 4.27 with the Toolchain v19 (clang-11.0.1-based). When compiling the game I'm getting the following linker errors:

discord_game_sdk.so: undefined reference to powf@GLIBC_2.27 [--no-allow-shlib-undefined]
discord_game_sdk.so: undefined reference to exp2f@GLIBC_2.27 [--no-allow-shlib-undefined]

Is there any way to fix this issue?

Steps to Reproduce

Use Unreal Engine Linux Toolchain v19 or newer to build an application with the Game SDK.

Expected Behavior

It compiles successfully without linker errors.

Current Behavior

It fails to compile with linker errors.

Client and System Information

• Game SDK 3.2.1
• Unreal Engine 4.27
• Unreal Linux Toolchain v19

It's available on the GameSDK overview page. Here is also a direct link.
