Bug: Unable to compile - junk_to_gold.h:54:81: fatal error: only virtual member functions can be marked 'override'

In this article, we will be discussing a bug that occurs when trying to compile the junk_to_gold module in the AzerothCore server. The bug is caused by a mismatch between the declaration and initialization of a member function in the junk_to_gold.h file. We will go through the steps to reproduce the problem, the expected behavior, and the extra notes provided.

The current behavior of the AzerothCore server is that it is unable to compile the junk_to_gold module due to a fatal error in the junk_to_gold.h file. The error message is as follows:

In file included from /home/steve/azerothcore/modules/mod-junk-to-gold/src/junk_to_gold.cpp:1:
/home/steve/azerothcore/modules/mod-junk-to-gold/src/junk_to_gold.h:54:81: fatal error: only virtual member functions can be marked 'override'
        void OnLootItem(Player* player, Item* item, uint32 count, ObjectGuid lootguid) override;

This error message indicates that the OnLootItem function is being marked as override, but it is not a virtual member function.

The expected behavior of the AzerothCore server is that it should be able to compile the junk_to_gold module without any errors.

To reproduce the problem, follow these steps:

  1. Update the playerbots core and modules to the latest versions.
  2. Compile the junk_to_gold module using the AzerothCore server.

No extra notes were provided.

The AzerothCore server is using the following versions:

  • OpenSSL: 3.0.15
  • Boost: 1.74.0
  • CMake: 3.25.1
  • MySQL: 80403
  • Linux: 6.8.12-5-pve

The operating system being used is Debian 12/Bookworm.

The following modules are enabled:

  • mod-ah-bot
  • mod-playerbots
  • mod-junk-to-gold

To solve this bug, we need to modify the junk_to_gold.h file to remove the override keyword from the OnLootItem function. This is because the OnLootItem function is not a virtual member function, and therefore cannot be marked as override.

Here is the modified code:

void OnLootItem(Player* player, Item* item, uint32 count, ObjectGuid lootguid);

By removing the override keyword, we can fix the bug and allow the junk_to_gold module to compile successfully.

In conclusion, the bug in the junk_to_gold module was caused by a mismatch between the declaration and initialization of a member function in the junk_to_gold.h file. By modifying the code to remove the override keyword, we were able to fix the bug and allow the module to compile successfully.
