[Is it stable? ...]

you know trinity is like the cms systems like joomla .

joomla only vulnerable to hack when you install a 3rd party modules . otherwise you should forgot about hacking that system

in trinity , its stable until you install the 3rd party scripts and stuff or modify the code by your self ( if you dont know the system )

so let us know if you have a costume scripts over there

thanks .

[Compile or cmake problems]

here is your problem

your patch is old . they change the error logs function

download the fixed script from attachment.

as you see in some lines

there is a slog function and as you see there is one more argument in the beggining

sLog->outError(LOG_FILTER_CHARACTER,"enchant_vendor::Enchant: Enchant NPC 'enchantid' is NULL, something went wrong here!");

you should tel the core that what is that outerror about .

read this : Core/Logging: Added documentation about this system · 52a5991 · TrinityCore/TrinityCore · GitHub for more info .

good luck .
