Ubuntu – ImageMagick PNG delegate install problems

imagemagickpng

Ubuntu 14.04:

I've downloaded the latest imagemagick source and installed, using option below to configure:

root@usve59445:~/im/ImageMagick-6.9.3-7# ./configure --enable-shared --with-png=yes

After installation however, I have zero items in my built-in list of delegates:

root@usve59445:~/im/ImageMagick-6.9.3-7# identify -version
Version: ImageMagick 6.9.3-7 Q16 x86_64 2016-03-14
Copyright: Copyright (C) 1999-2016 ImageMagick Studio LLC License:  
Features: Cipher DPC OpenMP
Delegates (built-in):

Issue I am getting is 'no delegate for format PNG found' when doing a convert command.

I installed the libpng delegate from: http://www.imagemagick.org/download/delegates/

Extracted the libpng1621.tar.gz into its own folder, then:
Ran configure, make, make install (no error messages)

Now when I try and recompile imagemagick, it still says ' Checking for PNG … no' and –with-png value has 'no' (even though I configure it with –with-png=yes ).

Not sure what I am doing wrong?

Trying to recompile IM using:

root@usve59445:~/im/ImageMagick-6.9.3-7# ./configure –enable-shared=yes –with-png=yes LDFLAGS='-L/usr/local/lib' LIBS=-lpng16

(I think I am using the correct LDFLAGS, but not sure)

root@usve59445:~/im/libpng-1.6.21# libpng16-config --L_opts
-L/usr/local/lib 

root@usve59445:~/im/libpng-1.6.21# libpng16-config --libs
-lpng16

You are making things a little too hard for yourself, here is a quick and dirty guide that ran well for me on Trusty Tahr:

First pick up a few known dependencies:

sudo apt-get install build-essential checkinstall \
             libx11-dev libxext-dev zlib1g-dev libpng12-dev \
             libjpeg-dev libfreetype6-dev libxml2-dev

This does not quite catch everything so activate the Source repositories by clicking on 'Souce Code' here:

Dash >> Software & Updates >> Source Code

and then running the following:

sudo apt-get build-dep imagemagick

Create a build folder and change to it:

mkdir $HOME/imagemagick_build && cd $HOME/imagemagick_build

And finally download, extract, compile and install by simply copying and pasting the entire code box below into a Terminal window:

wget https://www.imagemagick.org/download/ImageMagick-7.0.8-28.tar.bz2 && \
tar xvf ImageMagick-7.0.8-28.tar.bz2 && cd ImageMagick-7.0.8-28 && ./configure && make && \
sudo checkinstall -D --install=yes --fstrans=no --pakdir "$HOME/imagemagick_build" \
     --pkgname imagemagick --backup=no --deldoc=yes --deldesc=yes --delspec=yes --default \
     --pkgversion "7.0.8-28" && \
make distclean && sudo ldconfig

And finally test this, looking especially for the png you are missing in your own install:

andrew@corinth:~$ identify -version

andrew@corinth:~$ 

And there is the png option you were missing :).
