AC NPCBots pre-patched repository compilation issue - ISO C++ forbids forward references to 'enum' types

Greeting Gurus!

I have encountered an while trying to compile the AC NPC-Bot pre-patched repository https://github.com/trickerer/AzerothCore-wotlk-with-NPCBots/

And I have been trying to follow these instructions, https://github.com/trickerer/Trinity-Bots

However the compilation is failing.

As I am using the prepatched repository, I’m attempting to start from 'step 4 (Re) run CMake and (re)build'

To do this, I have run acore.sh and selected options:

• 5. compiler (c): Run compiler tool
• 5. all: clean, configure and compile

However, the compilation seems to fail. This is a link to a text file with the full output for reference https://mega.nz/file/HRJSkYYa#K_1hpeMXINnDWVahk1jtEtE9oC57ozUZHIC7IBfLxyY, however this is the section that appears to be going wrong:

Ultimately, the compilation then seems to fail before completing:

I have seen a few articles that recommend adding -std=c++11 to the compile instructions, but i don’t know where to set that as I’m not a c++ programmer, and am having difficulty tracing through the acore.sh script functions.

I anyone able to help me solve this?

Thanks in advance
