package 'poppler>=0.20.0' not found on CentOS 5

[haisum]

I am trying to cmake it on CentOS 5 and here's the output:

I installed every required package and utility. Any ideas what I am missing?

Pay attention to error message it says package 'poppler>=0.20.0' not found

[haisum]

I do have poppler installed

[haisum]

may be it should try to locate poppler like it does for fontforge if it's not found

[iapain]

It does try to locate poppler. Could you please check your poppler version?

[haisum]

I compiled it from http://poppler.freedesktop.org/poppler-0.20.5.tar.gz

[iapain]

can you locate your libpoppler.so ?

[haisum]

/usr/local/lib/libpoppler.so

$ ls /usr/local/lib | grep poppler
libpoppler.a
libpoppler-cpp.a
libpoppler-cpp.la
libpoppler-cpp.so
libpoppler-cpp.so.0
libpoppler-cpp.so.0.2.0
libpoppler.la
libpoppler.so
libpoppler.so.28

[iapain]

That's pretty odd. IMO cmake seems to be doing something weird while locating poppler. I don't have access to centOS so cannot say anything. BTW patches are always welcome here :)

[coolwanglu]

What's the output of pkg-config --libs poppler

And what's the content of /usr/local/lib/pkgconfig/poppler.pc

[haisum]

Since I compiled poppler myself, it didn't set environment variable PKG_CONFIG_PATH. So this is how I got it fixed:

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
cmake . -DCMAKE_C_COMPILER=/usr/bin/gcc44 -DCMAKE_CXX_COMPILER=/usr/bin/g++44

Thanks coolwanglu and iapain for your help :) and great work with this project coolwanglu 👍

Since I installed it successfully on CentOS here are steps I followed for reference of others:

• INSTALL LIBPNG
  **** THIS IS IMPORTANT TO BE INSTALLED FIRST
  http://sourceforge.net/projects/libpng/files/libpng15/1.5.13/

--if it fails for zlib requirement, install zlib from
http://sourceforge.net/projects/libpng/files/zlib/1.2.7/

• install poppler with xpdf header >= 0.20.0 (compile with --enable-xpdf-headers)
  http://poppler.freedesktop.org/poppler-0.20.5.tar.gz
• install poppler-data
  http://poppler.freedesktop.org/poppler-data-0.4.6.tar.gz
• install fontforge (with header files)
  http://sourceforge.net/projects/fontforge/files/fontforge-source/fontforge_full-20120731-b.tar.bz2/download
• On CentOS if you don't have gcc >= 4.4.6 you can use gcc44.
  To install gcc44 do
  yum install gcc44-c++ or yum install gcc44*

Then do

$ export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
$ cmake . -DCMAKE_C_COMPILER=/usr/bin/gcc44 -DCMAKE_CXX_COMPILER=/usr/bin/g++44
########### cmake . is to be run in directory containing source files of pdf2htmlEx###########
$ make
$ make install

[vungnhanh]

thanks haisum for the instructions above, I have installed
however, when run, I get the following error:

[....]#pdf2htmlEX --help
pdf2htmlEX: error while loading shared libraries: libfontforge.so.1: cannot open shared object file: No such file or directory

I have build pdf2htmlEX on CentOS 5.8 / 64bit

can you help me resolve problem ?

thanks

(sorry, my english is not good )

[haisum]

can you verify if libfontforge.so exists?
One of these commands should list it:

ls /usr/local/lib | grep fontforge
ls /usr/lib | grep fontforge

[vungnhanh]

Fontforge already exist
# ls /usr/local/lib | grep fontforge
libfontforge.la
libfontforge.so
libfontforge.so.1
libfontforge.so.1.0.0

I find that after set the LD_LIBRARY_PATH :
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
the above error is fixed
now, pdf2htmlEX works very well!

# pdf2htmlEX --help

thanks for all the help :)

[coolwanglu]

Congratulations!
And thank you @haisum for your info.

[jahewson]

@haisum why not use Yum?

[theZiki]

@jahewson how to use yum, it isn't in package manager?

[jahewson]

I mean use Yum to install Poppler and FontForge

[haisum]

Yum, in some distros might install older/incompatible versions, but there's no bad in installing it with yum if it works for you.

Here is my solution for CentOS .. It's a complete script that will do everything automatically.

#!/bin/bash

(deps)

echo "Installing Dependencies"
yum -y install gcc
yum -y install gcc-c++
yum -y install cmake
yum -y install libtool
yum -y install libpng-devel
yum -y install libjpeg-devel
yum -y install fontconfig-devel

(tmpdir)

echo "Preparing Directory"
mkdir -p /tmp/code
cd /tmp/code

(resources)

echo "Downloading Sources"
wget http://poppler.freedesktop.org/poppler-0.20.5.tar.gz
wget http://poppler.freedesktop.org/poppler-data-0.4.6.tar.gz
wget http://sourceforge.net/projects/fontforge/files/fontforge-source/fontforge_full-20120731-b.tar.bz2/download
wget https://github.com/coolwanglu/pdf2htmlEX/archive/v0.10.tar.gz
tar xfv poppler-0.20.5.tar.gz
tar xfv poppler-data-0.4.6.tar.gz
tar jxf fontforge_full-20120731-b.tar.bz2
tar xfv v0.10

(Installing)

echo "Installing"
cd poppler-0.20.5
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
./configure "--enable-xpdf-headers"
make
make install
cd ../poppler-data-0.4.6
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
cmake .
make
make install
cd ../fontforge-20120731-b
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
./configure "--without-libzmq" "--without-x" "--without-iconv" "--disable-python-scripting" "--disable-python-extension"
make
make install
cd ../pdf2htmlEX-0.10
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
cmake .
make
make install
echo /usr/local/lib > /etc/ld.so.conf.d/local.conf
ldconfig


[w2pmedia]

these instruction work great except for some minor issues( running on Centos 6.5)

• Make sure that you are running python2.7 environment
• Before you compile do the last steps in the instructions above
  echo /usr/local/lib > /etc/ld.so.conf.d/local.conf && ldconfig
• If python2.7 is in /usr/local/bin make sure that it's the first thing in your path and that it is linked to python
