Please add the output of `ldd test/libmupen64plus.so.2.0.0` (from the build 
directory) the and also provide the output of `dpkg -l|grep png`

I just tried to reproduce the problem. I've downloaded Ubuntu 10.04.03 LTS for 
amd64 (CD-Version). It is a vanilla installation (just pressed next during the 
installation and entered my user information). I installed all updates (just 
the stuff that the update manager showed me). Additional packages also 
installed for the build process:

 * libfreetype6-dev
 * libgl1-mesa-dev
 * libglu1-mesa-dev
 * libpng12-dev
 * libsamplerate0-dev
 * libsdl1.2-dev
 * mercurial
 * pkg-config
 * zlib1g-dev

After that I've done (in gnome-terminal):
$ mkdir m64p
$ cd m64p
$ wget 
https://bitbucket.org/richard42/mupen64plus-core/raw/cf106259e2a3/tools/m64p_hel
per_scripts.tar.gz
$ tar xvf m64p_helper_scripts.tar.gz
$ ./m64p_get.sh
$ ./m64p_build.sh

Now you should get an error because somebody forgot to add the zlib.pc (which 
was shipped in zlib 1.2.3.3) to the zlib1g-dev package.

The problem is... how did you compile it on a system with a "broken" zlib1g-dev 
package? Maybe you forgot to add some information to this bug report.

So I tried to find a way that you may have taken to build it. My first guess 
was to enable the lucid-backports archive and update my packages. But the 
zlib1g-dev package was not available in this repo.

So I went on and remove the zlib argument of the pkg-config calls in 
source/mupen64plus-core/project/unix/Makefile (and also removed the 3 lines of 
zlib check). I could continue to compile the code and start the test

$ ./m64p_build.sh
$ ./m64p_test.sh

Both worked fine and didn't show the problem you mentioned. I could only 
recreate the error after also removing the libpng from both pkg-config calls 
(which is nothing that you should do... also not the zlib part, but it is a 
small hack that worked in this situation).

You have to add the information about what you did. Otherwise we can't help you 
and have to mark this issue as invalid. At the moment, it just looks like you 
played around with the sources and added a bug by your changes.

Thanks

I tried to reproduce it and contact him by mail to resolve the problem. I will 
mark this bug as invalid because I got no reaction and the only way to get the 
same results was a manual edit of the Makefile

i actually have the same problem. i install from google code download, rather 
than repos. im running ubuntu 13.10 saucy. ive installed libpng15 from 
sourceforge download, because ubuntu repos only have libpng12.

 ldd /usr/local/lib/libmupen64plus.so.2.0.0  | grep png
    libpng15.so.15 => not found

pavel989, I recommend downloading the special Ubuntu version of mupen64plus on 
the download page.  This one was built on an Ubuntu system, and so it links 
against libpng12 and should work for you.

Thank you , im donwnloading , i wanna know why the download page , dont have 
the 32 Bits version for Ubuntu too ???

There's no 32-bit Ubuntu build because there was some particular technical 
reason why I could not compile it on my Ubuntu machine. :)  I tried to, but for 
reasons I can't remember now I ran into some problems and decided to give up.

just for curiosity , you try installing the "ia" libs , i cant remember the 
exact name of libs of 32 bits under Ubuntu x86_64 , and run from the terminal 
using something like

hostname@machine $ linux32
$ ./autogen.sh && ./configure --and --the --options

???

Yes, those are the run-time 32-bit compatibility libraries.  I have all of 
those on my ubuntu machine.  I think there was a problem in which a 32-bit 
development package was unavailable or couldn't coexist with the 64-bit 
version.

Thank you for your answers , well you can tell me , the libs are need in the 
version of 32 Bits of Ubuntu , to manual compilation ??? . i can try build the 
lastest source code. :D

There is a wiki page here which lists most or all of the dependencies:

https://code.google.com/p/mupen64plus/wiki/CompilingFromGit

It may be a little out of date.  To build on Ubuntu, you need the development 
packages for these libraries.  For example, the SDL development package is 
called "libsdl1.2-dev"
