CentOS Specific Install Instructions

To install on CentOS:

Following the instructions from this link

On CentOS

On CentOS the libpoppler-cpp library is not included with the system so we need to build from source. Note that recent versions of poppler require C++11 which is not available on CentOS, so we build a slightly older version of libpoppler.

# Build dependencies
yum install wget xz libjpeg-devel openjpeg2-devel

# Download and extract
wget https://poppler.freedesktop.org/poppler-0.47.0.tar.xz
tar -Jxvf poppler-0.47.0.tar.xz
cd poppler-0.47.0

# Build and install
./configure
make
sudo make install

By default libraries get installed in /usr/local/lib and /usr/local/include. On CentOS this is not a default search path so we need to set PKG_CONFIG_PATH and LD_LIBRARY_PATH to point R to the right directory:

export LD_LIBRARY_PATH="/usr/local/lib"
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"

CentOS moved some devel packages into the PowerTools repo, looks like. Just spun up CentOS 8 and this seems to work:

yum install dnf-plugins-core
yum config-manager --set-enabled PowerTools
yum install gcc-c++ pkgconfig poppler-cpp-devel python3-devel
pip3 install pdftotext

You can use the latest version of poppler if you want, but you won’t find the latest version of just about anything in normal CentOS packages 🤷‍♂️

@jalan Thank you very much for quick answer! I am up and running thanks to you. Would probably wasted many hours and still not arrive to the same result as you provided. You have been helpful! I am using your project with another project (SeedDMS).
