Common Errors

"Play Dwarf Fortress" button does nothing when attempting to launch DF with DFHack enabled

stderr.txt in the root of the pack should show the following errors:

Exception in Tkinter callback
Traceback (most recent call last):
  File "/home/michael/Desktop/df/python_lnp/build/lnp/out00-PYZ.pyz/Tkinter", line 1532, in __call__
  File "/home/michael/Desktop/df/python_lnp/build/lnp/out00-PYZ.pyz/core.launcher", line 52, in run_df

TypeError: coercing to Unicode: need string or buffer, list found

Solution:

Make sure you have correctly configured your terminal for launching DF.

• Go to File -> Configure Terminal
• Double-check the drop down menu to ensure you have specified a terminal installed on your system
• Double-check the text field below the drop down menu to ensure that if a custom command is specified, that "custom command" is also specified in the drop down menu.
• If a custom command is specified, click on the Test custom terminal button to ensure PyLNP is able to launch DF/DFHack properly.

"Could not find PNG file: Ironhand 16x16.png" or "libstdc++.so.6: version `CXXABI_1.3.8' not found"

Solution 1:

Download the latest distro_fixes.sh and replace the copy in your DF folder with it.

If libstdc++ errors persist, try deleting or renaming libs/libstdc++.dylib.

Solution 2 (tested on Arch):

• Install vanilla Dwarf Fortress, check that it starts up.
• Open a terminal and create a symlink to the vanilla DF copy of libgraphics.so in the LNP libs directory - first remove the LNP version:

$ rm /path/to/lnp/df_linux/libs/libgraphics.so

• Then create the symlink:

$ ln -s /opt/dwarffortress/libs/libgraphics.so /path/to/lnp/df_linux/libs/libgraphics.so

or if the above doesn't work, try:

$ ln -s ~/.dwarffortress/libs/libgraphics.so /path/to/lnp/df_linux/libs/libgraphics.so

• Try to restart LNP DF, if you get an error about libstdc++.so.6 then you'll need to create a symlink to that too. Find where libstdc++.so.6 is on your system:

$ whereis libstdc++.so.6

libstdc.so: ... /usr/lib/libstdc++.so.6

• First remove the LNP version:

$ rm /path/to/lnp/df_linux/libs/libstdc++.so.6

• Then create the symlink to the path that whereis gave you:

$ ln -s /usr/lib/libstdc++.so.6 /path/to/lnp/df_linux/libs/libstdc++.so.6

• Start DF!

On Arch there are also a couple of broken symlinks in the LNP DF libs folder:

libopenal.so -> /usr/lib/i386-linux-gnu/libopenal.so.1

libsndfile.so -> /usr/lib/i386-linux-gnu/libsndfile.so.1

They didn't cause any problems for me, but you can symlink these to /usr/lib/* using the same method above if you're still having issues (e.g. no audio, as they look related to sound)

Solution 3:

1. Install vanilla dwarf fortress, verify that it works.
2. Find the file called "libgraphics.so" in the normal dwarf fortress install location.
3. Copy that file into "lnp install folder/df_linux/libs" and overwrite the existing file.
4. Try "sudo ./startlnp" again and click start. If dwarf fortress does not open, or you get some error, delete the file named something like "libstdc++.so" in "lnp install folder/df_linux/libs". -- DwarfMonad
