Installation of Poppler

Install Poppler by running the following commands: 

mkdir build                         &&
cd    build                         &&

cmake  -DCMAKE_BUILD_TYPE=Release   \
       -DCMAKE_INSTALL_PREFIX=/usr  \
       -DTESTDATADIR=$PWD/testfiles \
       -DENABLE_XPDF_HEADERS=ON     \
       ..                           &&
make

In order to run the test suite, some testcases are needed and can be obtained only from a git repository. The command to download them is: git clone git://git.freedesktop.org/git/poppler/test testfiles. Then issue: LC_ALL=en_US.UTF-8 make test. Only the Qt5 libraries are tested.

Now, as the root user: 

make install

To install the documentation, run the following commands as root: 

install -v -m755 -d           /usr/share/doc/poppler-0.67.0 &&
cp -vr ../glib/reference/html /usr/share/doc/poppler-0.67.0

Poppler Data

If you downloaded the additional encoding data package, install it by issuing the following commands: 

tar -xf ../../poppler-data-0.4.9.tar.gz &&
cd poppler-data-0.4.9

Now, as the root user: 

make prefix=/usr install

Command Explanations

-DCMAKE_BUILD_TYPE=Release: This switch is used to apply a higher level of compiler optimizations.

-DTESTDATADIR=$PWD/testfiles: Tell the test programs where the auxiliary files are located.

-DENABLE_XPDF_HEADERS=ON: Install some old Xpdf headers required by certain programs (e.g. Okular, LibreOffice and Inkscape).

LC_ALL=en_US.UTF-8 make test: Run the test suite. The environment variable LC_ALL=en_US.UTF-8 is only needed if the default locale does not include UTF-8.
