Segfault on VMap Extraction


Question

Hi All,

I am trying to set up MaNGOS One, but am having issues with generating the vmaps. This is running on an Ubuntu 20 LTS machine. I included what I thought were the relevant logs. Any thoughts as to what the issue would be would be greatly appreciated.

 

Thanks!

I assume that you have good (i.e. not broken) client files. Then you could try to do the extraction under Windows to ensure the file names are case insensitive. The same can be achieved under Linux at a FAT32 filesystem. I had an issue once (with a Camera file though) of capsed/not capsed file name.

I ran into this problem with the Zero (non-BC) client files. `std::bad_alloc` is a general libstdc++ error that indicates the pointer tried to allocate new[] beyond usable system memory. Turns out I was using a VM that had only 2GB allocated to it (!) so I upped it to 4GB and it succeeded. I would check to make sure something else on your system isn't hogging more available memory and try. I don't know what the bare minimum is but apparently 2GB is definitely not enough. ;)
