I was setting up SoundSense for the first time and of course it needed to download the sound files. There was a Java error about a missing folder so I had a look.

../df_linux/sounds exists but ../df_linux/sounds/packs does not.

As soon as I created the df_linux/sounds/packs folder and restarted SoundSense it immediately started getting the sound files, albeit very, very slowly. Total download size is  347Mb.

EDIT : I did discover that SoundCense is looking for ../df_linux/sounds too instead of ../df_linux/sounds/packs. It may be simpler to edit where SoundSense is expecting to download its files to.

Another issue is an error thrown by SoundCense...

Now I think I have Mono installed (Mint 18) but this error was thrown from the LNP Utilities screen without DF running. Is this expected behaviour or do I need to check something?

hm, 43.05 update expected any time soon?

[Fleeting Frames]

You can help by testing dfhack alpha for bugs, crashes and save corruption.

But yeah, should be soon-ish.

[Turtoksimal]

For everyone using LUbuntu 16.04.1 x64 (works probably also on Ubuntu and the oteher Ubuntu's), these are the steps i had to do to make LinuxLNP-0.43.03-r04 play like it should:

sudo apt-get install libsdl-image1.2:i386 libgtk2.0-0:i386 libsdl-ttf2.0-0:i386 libglu1-mesa:i386 libopenal1:i386

for some reason some parts of LNP prefer xterm and cannot find any other terminal:

sudo apt-get install xterm

now create a folder and unpack the tar-file into it, go into the folder and start LNP:

./startlnp

it will configure some stuff, you will have to choose xterm at some point.

The startscript configures some stuff to make DwarfTherapist access the memory of DwarfFortress. I think that is why LNP asks you for your password somewhere in the starting process. This has not worked for me.

I had to set some ptrace configuration manually:

sudo your-favorite-editor /etc/sysctl.d/10-ptrace.conf

change:

kernel.yama.ptrace_scope = 1

to:

kernel.yama.ptrace_scope = 0

this will be active after restarting the system.

If you cannot wait to start it (like me) then do this in the terminal where you want to start LNP:

echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope

it took me some hours to find this out. I hope it might be some help to someone.

Also: all of this works with /bin/sh being pointed to dash (as contrary to bash) and you don't have to start your stuff with sudo and root rights, which is a very bad idea in general.

DwarfFortress RULES!!!!

[Fleeting Frames]

Though I'm not sure launching just the DT with sudo is worse than giving all apps ability to access each other memory (guessing, if that disables DT sudo), that's pretty nice set of instructions, especially to have in one place - didn't know or still not remember about changing ptrace_scope, myself.

to:

this will be active after restarting the system.

There is a better way!! Change into the DwarfTherapist directory and "sudo setcap cap_sys_ptrace=ep DwarfTherapist". This will disable ptrace access for DT only.

The difference is that "kernel.yama.ptrace_scope = 0" will allow all software in your session to access memory space allocated to other apps, meaning that some hacked internet browser site/script can exploit some security flaw in another running app on your machine, and allow long-term infection. It would not matter if you were playing DF or not, the risk exists while ptrace is disabled. A purpose of ptrace protection is to prevent malicious software from being able to inject malware code into other running software.

By only allowing ptrace access to DwarfTherapist, you are minimizing the risk. You can go through the DT source code and see what it is capable of.

Though I'm not sure launching just the DT with sudo is worse than giving all apps ability to access each other memory (guessing, if that disables DT sudo), that's pretty nice set of instructions, especially to have in one place - didn't know or still not remember about changing ptrace_scope, myself.

Running DT with sudo is *much* safer than disabling all ptrace protection, for the reasons above.

[Turtoksimal]

I am aware of that one. I tried it out, even with ..cap_sys_ptrace=eip. I checked the values with:

Code: [Select]

getcap ./DwarfTherapist
DwarfTherapist = cap_sys_ptrace+eip

As you see, the values are set but it is not working. I still get the errors:

Code: [Select]

and on the GUI:

A fort has not been loaded. ...

I tried to find information about why it might not be working on Ubuntu but so far i was unsuccessful.

A purpose of ptrace protection is to prevent malicious software from being able to inject malware code into other running software.

Of course you are absolutly right and i had not considered the danger of this setting before.

By the way, i upgraded to Ubuntu 10.14 Ubuntu 16.10 in the hope that it could solve my problem. It did not.

But i found out that you have to make some changes in df_linux/distro_fixes.sh. The place for zlib1 changed.

On line 24 i had to add: /usr/lib/i386-linux-gnu /lib/i386-linux-gnu/ or you will get errors when you try to start LNP, something like:

Could not find a 32-bit zlib

Maybe some one could put the change into the LNP-package.

So far i will still try to find out why DwarfTherapist cannot be started with ptrace settings. I really need DwarfTherapist!

EDIT: Typo OS version, wrong path

Someone did, 5 months ago. It's possible that you're using an old pack, or that your pack hasn't been updated since then.

WOW !! that was a really fast answer!!

Sorry, i was wrong, i messed up the path, it actually is: /lib/i386-linux-gnu/

I downloaded the package from here. Is that the right place?

I downloaded it right now and tested it just to be sure and it is now the right path.

[Fleeting Frames]

By the way, i upgraded to Ubuntu 10.14 in the hope that it could solve my problem. It did not.

Typo? Since I'd think that'd be a downgrade from Lubuntu 16.04

Heh, I must have checked the forums just at the right time. I didn't even notice how recent that post was.

That is indeed the right place for the pack that this thread is about. I probably missed the thread title and thought you were talking about an older pack, which a lot of people reported issues with since it used an older version of that script. Anyway, feel free to make a pull request if adding /lib/i386-linux-gnu is necessary for you, since it might help others as well.

[Ikkitsyne]

Hi, i was trying to get LNP working for a while, but as you may  guess without success and i decided to write here. So problem is that i can run DF and DFHack but when i try to launch LNP i get this:

Spoiler (click to show/hide)

And i get this error whenever i use latest LNP from this thread or any other version (40.2 ;42.2), i assume that problem is  with PyLNP itself, but i was not able to find any solution or information about this. So any info/help appreciated. Thanks is advance.

Hello folks,
PyLNP 0.12a (latest) has an issue, armok vision doesn't work when launched from the startlnp.

It simply outputs the following into the terminal

Furthur digging shows that running "~/Documents/df/LNP/utilities/armok_vision/Armok\ Vision.x86" and "~/Documents/df/LNP/utilities/armok_vision/Armok\ Vision.x86_64" from the terminal does work.

Renaming libxcb-dri3.so.0 to libxcb-dri3.so.0.bak gives this when run from the lnp but works fine when run from the console:

Code: [Select]

/home/gentz/Documents/df/LNP/utilities/armok_vision/Armok Vision.x86_64: error while loading shared libraries: libxcb-dri3.so.0: cannot open shared object file: No such file or directory

For some reason Armok is using outdated libraries when run with the lnp.

Another issue is that when it runs it leaves many blocks transparent, others pitch black and ect. Its also performing at less than 10fps.

Hopefully someone can help fix this for me.
Thanks in advance

Hello all,

Near identical issue to Ikkitsyne.
I do have PyLNP.user, I have the "placeholder paths" with Michael in them and my _tkinter.TclError is unknown color name.
I have seen many references to this issue but nothing as a definitive answer.
Im running Xubuntu 16.04.1, the latest LNP 0.43.03-r04 and python 2.7.12//3.5.2 and python-tk
Most solutions I've seen either dont work, or reference files I dont have.
I get the exact same issue launching PyLNP by itself, but Vanilla Dwarf Fortress will launch correctly.
Any thoughts or assistance is greatly appreciated.  Thank you.
