Yey, another question from the newb'

As said juste before, i'm trying to use DFHack on the latest version of DF on an Ubuntu Linux.

After some aventures with CMake, I have compiled the tools for Linux, but when I try to launch the dfcreaturedump tool, I just get an std::bad_alloc exception.

I've tried to look in the code, and this exception is raised when the program is trying to read all the materials of DF (line 443, Search the string "Just Here" if you're interested)

I was wondering if the problem was coming from DF, so I just get a look in the df-hacked script, in the ./precompiled/linux directory of the DFHack distrib, and it seems that the library libdfconnect.so in the same dir must be moved in the libs directory of the DF distribution

So, i made the three following things :

• Copy the libdfconnect.so from its origin dir to the libs dir of the DF distribution
• Copy the fd-hacked script from its origine dir to the root of the DF distribution
• Modify the fd-hacked script for using the ./libs/Dwarf_Fortress exec instead of dwarfort.exe

But again, no luck, same error.

So, at the end, I have two questions :

• Does the last version of DFHack works with the last Linux version of DF ? EDIT : Work for some tool. Seems to be, only the dump tools are not working
• If yes, how can I use the DFHack tools (and later, the lib) with DF ?
