0002688Dwarf FortressInit Optionspublic2010-07-14 03:142018-05-27 11:57
Assigned ToToady One 
PlatformLinuxOSGentooOS Version~AMD64
Product Version0.31.10 
Target VersionFixed in Version0.43.05 
Summary0002688: Not found: data/art/curses_640x300.png (32-bit Linux DF)
DescriptionI could have sworn I had dwarf fortress running at one point. Maybe it was all a dream.

Anyway. At first I was getting the "Not found: data/art/curses_640x300.png" error. I changed all occurrences of ".png" to ".bmp" in data/init/interface.txt

Now I'm getting the mouse.png not found error. Setting "[MOUSE:NO]" and "[MOUSE_PICTURE:NO]" doesn't fix it.

Just a heads up.
Steps To ReproduceTry to run ./df
Additional InformationI have libpng, sdl-image, and all other necessary requirements. This is a 64bit system, so maybe it's unsupported. Either way, there are no 32bit builds of any of the above packages for Gentoo.
Tags0.44.10, 32-bit DF only

I changed all occurrences of ".png" to ".bmp" in data/init/interface.txt

Did you mean init.txt?

Reminder sent to: gone404

Is this error still present in 31.12?

I did mean init.txt.

Error is still present (df_31_12_linux.tar.bz2). Changing all occurances of .png to .bmp gets rid of the curses_640x300 error. But the "Not found: data/art/mouse.png" error still comes up. This happens whether [MOUSE] is set to "YES" or "NO"

I've also tried running ./libs/DwarfFortess directly as well as executing df with a full path. Nothing seems to help.

Update: Hex editing df_linux/libs/DwarfFortress and replacing "mouse.png" with "mouse.bmp" lets me run DwarfFortress!

It was a bit of a crapshoot, but luckily the reference was a string in the binary.

Cool intro by the way =)

NOTE: I had to set MOUSE_PICTURE:NO because the ax cursor was blank when mousing into the df window.

Hey Baughn, any input on this one? gone404 did some testing (see above) which may shed some light on the problem.

It seems like an issue with png processing. I've been testing tilesets and raw/graphics/ packs (mayday). Nothing works until I change the the images to bitmaps and update the references accordingly.

i have similar problem
OS: ArchLinux 64 bit
df: 0.34.11-2 (arch package) 0.34.11 (official package)

resolution: delete all png, link all bmp to respective names ending in png

So, I got this same problem after upgrading to Fedora 20, and investigated it.

It seems, from DF statically links to zlib and exports all of its symbols, so the system's libpng ends up calling the functions in libgraphics instead of the system zlib. Apparently something changed in the zlib API recently, and recent libpng versions rely on it, so on an up to date system it fails to work.

A solution I found is to preload the system zlib, so that it has priority over libgraphics:

export LD_PRELOAD=/usr/lib/

Thank you ag!

LD_PRELOAD=/lib32/ ./df

worked for me on Gentoo!

This is still an issue on 0.40.01 and 0.40.02 (and was an issue with me with 0.34.11 days before 0.40.01 was released).

I am on Gentoo using emul-linux-x86-baselibs 20140406-r4, which provides me with 32-bit libpng and libz libraries. Using the LD_PRELOAD given in the previous note throws a couple of "ERROR: object '/lib32/' from LD_PRELOAD cannot be preloaded: ignored." but otherwise runs fine.

Trying to specify /usr/lib32/ interestingly causes the fatal error to occur, despite it also being installed by that emul-linux package. Not sure why this is, but I should note that I have libpng libraries in /usr/lib32, while not having them in /lib32

That's about all I can find at the moment, hope it's helpful in some fashion.

1) Over /usr/lib32/ fatal issue:
On gentoo, is ascii file with 'GNU ld script' inside.
neko@laptop : ~
[0] % file /usr/lib32/
/usr/lib32/ ASCII text

2) Over LD_PRELOAD issue:
This is because you have 64bit environment at the moment of the script (df) launch.
ld is smart & won't preload wrong architecture library for you.
your /bin/sh is 64bit, library is 32bit, script is executed with /bin/sh, thus problems.
However it is unclear why, while LD_PRELOAD doesn't preload the library, it fixes the issue for you.
ag (reporter)
2014-07-15 11:15

Because LD_PRELOAD independently applies to every process that is started by the command, so /bin/sh complains, but the actual DF executable doesn't even know about that and works.
djsmiley2k (reporter)
2014-07-23 15:12

On gentoo I've had to add

export LD_PRELOAD=/lib32/ libs/Dwarf_Fortress #gentoo hax

and then it works normally as far as I can tell.

recompiling also works (obviously)

I've modified the Linux df script so that it should work under most 64 bit Linux systems. See [^]
Quietust (reporter)

This issue should not be confused with 0006147 - despite having the exact same title, this one applies to Linux while the other one applies to Windows (and is actually a totally different problem).
braiam (reporter)
2016-06-09 05:41

On Debian the library is in `/lib/i386-linux-gnu`, so adding that to Khym script should work for Debian derivatives [^]

As far I know, the dynamic linker should have found it as ldd output shows:

ldd df_linux/libs/Dwarf_Fortress | grep libz => /lib/i386-linux-gnu/ (0xf62ad000)

But `ld ./libs/DwarfFortress` throws:

➜ ~ ld df_linux/libs/Dwarf_Fortress
ld: i386 architecture of input file `df_linux/libs/Dwarf_Fortress' is incompatible with i386:x86-64 output
ld: error in df_linux/libs/Dwarf_Fortress(.eh_frame); no .eh_frame_hdr table will be created.
ld: warning: cannot find entry symbol _start; defaulting to 0000000000404a20

Which according to this [^] some emulation should be used. Since the compiler is new, I presume Toady hasn't been able to get around it, yet.
lethosor (manager)
2016-06-09 08:32

The compiler hasn't changed since around 2010, so I don't know what you mean. There's no need for emulation. Does actually running DF work?
lethosor (manager)
2016-08-22 14:34

Okay, now Toady has upgraded his Linux toolchain. Is this still an issue with DF 0.43.05? I was able to run both builds on Ubuntu 16.04, but I haven't tried other distros.
Max_TM (reporter)
2016-08-24 15:38

Worked for me on Arch straight from him, no more editing the executable with vim until the arch build is ready!
braiam (reporter)
2016-08-25 14:27

I swear I responded to lethosor comment... yes, it works without a hitch on a Debian testing. The user only needs to install the libraries, not even the 32-bit build, but the 64-bit ones.
lethosor (manager)
2018-04-10 10:36

Okay, thanks, we'll call it fixed in 0.43.05, then. PM a manager on the forums if it persists in anything newer than that.

Reopening per 0010771

Possibly missing an "-lz" in the build script, from what I understand.
