problem with 'libpng' install on tiger

By splaisan at Wed, Jul 16 2008 4:24am |

Hi there,
Is this not the right place for such topic => my apologies

======PB======
I struggled yesterday to install ebiotools and other unix apps on a good old Tiger G4 desktop serving my ex-lab.

All went more or less fine after aliasing some config.files but concerning the libpng I did not make it.

ebiotools did it well but emboss-explorer installation is missing PNG output and only accepts to make PS files (not so nice for users who need to open them in preview and convert to PNF).

I installed libjpg and libpng from the package libjpeg-libpng (universal).dmg that I found on the net (not better)

I then tried to build libpng from the sourceforge builds but libpng does not work and returns error 1 during install.

libpng-1.2.24.tar.bz2
libpng-1.2.29.tar.gz

still no success.

Does someone know which problem is preventing the installation (some renamed apple config file or path?

The installation on my MPB leopard went fine for all these tools, it is a tiger 'problem'

Thanks for any advice.
Stephane

config options

Not sure if this helps: Back when I compiled Apache 2.2 from source, I ran into a similar problem, although with libpng 1.2.12 back then. Configuring and building like follows was successful however, try if that solves your problem, too. If not I suggest you tell us what errors you get when compiling.

./configure --prefix=/usr/local && make && sudo make install

XCode should come with libpng

If you've got XCode (and X11, I guess), you already have libpng

Check in: /usr/X11R6

The lib directory there has the libpng files.

I don't know if this leopard only, as I don't have a tiger machine to test. You can find reference to this in this post:

http://ipython.scipy.org/moin/Py4Science/InstallationOSX

under the matplotlib section.

Although you aren't building those packages, still there's an example of using the libpng on the system.

If that doesn't work, you might want to look at the pre-built frameworks here:

If you look at the "UnixImageIO framework" section, you'll see there is some sort of PNG library there. I haven't used this particular framework, so I don't know if it's going to scratch your itch. I'm just pointing out that it's there.

HTH,
