[SOLVED] libpng error: Incompatible libpng version in application and library

Stragonian · 07-28-2011, 02:35 AM

Trying to run Sauerbraten and Frozen-Bubble on Slackware 13.1 - I get ...

sauerbraten:

Code:

libpng warning: Application was compiled with png.h from libpng-1.4.2
libpng warning: Application  is  running with png.c from libpng-1.2.43
libpng error: Incompatible libpng version in application and library

frozen-bubble:

Code:

libpng warning: Application was compiled with png.h from libpng-1.4.2
libpng warning: Application  is  running with png.c from libpng-1.2.43
libpng error: Incompatible libpng version in application and library

I've tried recompiling the libpng 1.4.2 package with the ln -sf libpng.so.3 libpng.so.0 uncommented from the Slackbuild script, and recompiled gd, and still haven't had any success.

Oh! and add to that list Supertux2 as well

Supertux2:

Hi

As said, the binary you use was compiled with a different version of the libpng shared library...

You're post is lacking of a lot of context: did you try to compile it yourself ? How did you install that ?

If it's a precompiled binary, it's not compatible with the runtime version installed on your slackware...

If you compiled it yourself, you might have also used a 'custom' version of libpng which is NOT the version installed on your system, but I doubt you did that, and guess that you simply installed a binary.

Stragonian · 07-29-2011, 03:16 PM

The version of libpng that I am using is from the source/l/libpng directory of the Slackware 13.1 DVD ISO image downloaded via Bittorent from the Slackware Website. I do recompile the libpng using the libpng.SlackBuild script supplied by the DVD but I uncomment the section:
libpng.SlackBuild

Code:

# I'm ditching this to see if anyone cares.
#
## This symlink is needed to keep old applications running:
## I guess the real lib used the major number 3, then 0 for
## a short while, and now .3 again.  Hopefully it will stay
## this way as it was .3 in Slackware 10.2.  One can hope.
( cd $PKG/usr/lib${LIBDIRSUFFIX}
  if [ ! -e libpng.so.0 -a -e libpng.so.3 ]; then
    ln -sf libpng.so.3 libpng.so.0
  fi
)

I then recompile libpng and when it is finished I install the newly compiled binary using:

Code:

upgradepkg --reinstall --install-new /tmp/libpng-1.4.2-i486-1.txz

Then per the instructions from the libpng website I recompile gd from the source/l/gd directory of the Slackware 13.1 DVD ISO image and use the gd.SlackBuild to rebuild the package.

Code:

upgradepkg --reinstall --install-new /tmp/gd-2.0.35-i486-4.txz

Why are you recompiling libpng? Do you have a reason for uncommenting the above lines in the build script? Why aren't you using the most up to date version of libpng provided for Slackware 13.1 (1.4.3)?

Why are you recompiling gd? The gd package included with Slackware 13.1 is already linked against the libpng14 library, not the libpng12 library.

What "problem"? You provide a link to an FAQ, not a link to your specific issue.

To reiterate what NoStressHQ asked, how are you installing the software you are trying to run (the programs listed in your first and second post)?

dugan · 07-29-2011, 05:19 PM

Are you by any chance using a very old set of my font-rendering patches? Say, from before July of 2010? Some early versions (from around that time) had bugs that could cause this problem.

The current versions, needless to say, can run build and run Frozen Bubble just fine. I just tried it.

Stragonian · 07-29-2011, 07:17 PM

(Mike_M) I recompiled libpng to begin with because I got the following error when I tried to play Sauerbraten and figure I'd try uncommenting the libpng.so.0 portion of the libpng.Slackbuild script to see if that would help ... it didn't!

Code:

libpng warning: Application was compiled with png.h from libpng-1.4.2
libpng warning: Application  is  running with png.c from libpng-1.2.43
libpng error: Incompatible libpng version in application and library

I finally got the libpng problem solved. Turns out when I compiled both gd and SDL_image they link with libpng 1.2.43 by default if I recompile the slackware 13.1's libpng.Slackbuild and comment out everything that has to do with libpng 1.2.43 and recompile the package with only the libpng 1.4.2 library then recompile gd and SDL_image I can then play Sauerbraten, after which if I recompile frozen-bubble, and Supertux2 they both work.

gd was:

Code:

checking for libpng12-config... /usr/bin/libpng12-config
checking for libpng-config... /usr/bin/libpng-config

gd now:

Code:

checking for libpng12-config... no
checking for libpng-config... /usr/bin/libpng-config

SDL_image was:

Code:

-- dynamic libpng -> libpng.so.3

SDL_image now:

Code:

-- dynamic libpng -> libpng.so.14

Ok, so here is what I did:

1. I comment out everything libpng 1.2.43 from the DVD libpng.SlackBuild script then recompile and install

Comment out 1.2.43 stuff:

Code:

# VERSION_OLD=1.2.43
...
# VERSION=$VERSION_OLD
# build_source

2. Recompile gd from the DVD gd.SlackBuild script and got

Code:

checking for libpng12-config... no
checking for libpng-config... /usr/bin/libpng-config or /usr/local/bin/libpng-config

appears in the configuration

3. Recompile SDL_image.SlackBuild using this SDL_image.SlackBuild the script below

Code:

#!/bin/sh

PRGNAM=SDL_image
VERSION=1.2.10
TAG=${TAG:-_SBo}

if [ -z $DISTRIBUTION ]; then

4. Reinstall sauerbraten - Works
5. Recompile frozen-bubble from Slackbuild.org - Works
6. Recompile Supertux2 - Works

Oh hey .... then I reinstall the original libpng-1.4.2 from the Linux distro after I recompile gd and SDL_image

I wrote a bash script that fixes this for me, if you have an x86_64 and have not installed Alien Bob's compat32 library's then you'll need to comment out that part of the script.

Code:

#!/bin/bash

       *) ARCH=$( uname -m ) ;;
  esac
fi

if [ "$ARCH" = "i486" ]; then
  LIBDIRSUFFIX=""

  LIBDIRSUFFIX=""

fi

        # remove Alien Bob's compat32 libpng library
	removepkg libpng-compat32-1.4.2-x86_64-1 
fi

# Find the libpng package files and remove them
LIBPNG_PACKAGE=$(ls /var/log/packages | grep libpng)
removepkg $LIBPNG_PACKAGE

# Clean up the remaining files

If you want to compile and install through the whole process then add the DO_INSTALL logic to all the affected scripts for compiling.

parent script

Code:

export DO_INSTALL="YES"

child script

Code:

if [ "$DO_INSTALL" = "YES" ]; then
         # I just usually copy the makepkg package name
	upgradepkg --reinstall --install-new <package name here>

Just a quick reading, and I'd suggest:

Code:

DIR="$(cd "$(dirname "$0")" ; pwd -P)"

instead, so you can launch it from any directory (as far as your script resides in the base directory you're doing your stuff)....

Also a lot of double quotes are missing in the directories name, and so it doesn't handle directories with spaces...

Edit: Sorry for the next remark, you used it well, I don't understand, I might have read to fast, but I can't find the place that shocked my eyes ... My bad...

Edit 2: Oh yes, it was that:

Code:

cd ${DIR}/SourceCode/libpng

As a side note too, ${var} is really necessary, in some case, mostly when you want to merge strings like this:

Code:

MERGED="${PREFIX}suffix"

But it's useless if used glued to other chars not used into variable identifiers like:

Code:

MERGED="$PREFIX-suffix"  #<- totally valid..

it's not a big deal, but I find it (personally) easier to read this way.

There might be some more improvements, it was just a quick overview.

Btw, I don't have any problem with this, but thank you anyway, this may be helpful for some users.

Cheers

Garry.
