Linux, error : "undefined symbol"

[Tchey]

Hello,

I wanted to try again this game, but i have trouble installing it. I have the game's data from Steam, so i use PlayOnLinux to install X-COM with Steam Windows, then make a copy the folder.

I had a working version before, it was "1.0.518a651-dirty". I didn't really play it, it was just a test, and it was about one year ago i think, but i could launch a game and all was fine.

So i tried to remove it to installed the latest Nightly :

Code: [Select]

sudo remove openxcom

I follow the steps on the webpage for Linux Ubuntu (i'm on Mint but it's more or less the same) :

Code: [Select]

sudo add-apt-repository ppa:knapsu/openxcom-beta
sudo apt-get update
sudo apt-get install openxcom

Then i go to /home/tchey/.local/share/openxcom/UFO/

and i copy the files from my X-COM vanilla into it and replace the previous ones.

Then i open a terminal like i used to do for the "dirty" version :

Code: [Select]

openxcom
 Now i have this error :

Code: [Select]

~ $ openxcom
openxcom: symbol lookup error: openxcom: undefined symbol: _ZN4YAML6detail9node_data12empty_scalarB5cxx11E

What did i do wrong ? Thanks for reading.

check what version of yaml-cpp you have.
