Introduction to Poppler
The Poppler package contains a PDF
rendering library and command line tools used to manipulate PDF
files. This is useful for providing PDF rendering functionality as
a shared library.
This package is known to build and work properly using an LFS 12.2
platform.

Additional Downloads
The additional package consists of encoding files for use with
Poppler. The encoding files are
optional and Poppler will
automatically read them if they are present. When installed, they
enable Poppler to render CJK and
Cyrillic properly.
Poppler Dependencies
Required
CMake-3.30.2, Fontconfig-2.15.0,
and GLib-2.80.4 (with GObject Introspection)
Recommended
Boost-1.86.0, Cairo-1.18.0, GPGME-1.23.2, Little CMS-2.16, libjpeg-turbo-3.0.1,
libpng-1.6.43, libtiff-4.6.0, nss-3.103,
OpenJPEG-2.5.2, and Qt-6.7.2 (required for PDF
support in okular-24.08.0)
Optional
cURL-8.9.1, gdk-pixbuf-2.42.12, git-2.46.0 (for downloading test
files), GTK-Doc-1.34.0, GTK+-3.24.43, and
qt5-components-5.15.14
Installation of Poppler
Now, install Poppler by running
the following commands:
mkdir build &&
cd build &&
cmake -D CMAKE_BUILD_TYPE=Release \
-D CMAKE_INSTALL_PREFIX=/usr \
-D TESTDATADIR=$PWD/testfiles \
-D ENABLE_QT5=OFF \
-D ENABLE_UNSTABLE_API_ABI_HEADERS=ON \
-G Ninja .. &&
ninja
In order to run the test suite, some testcases are needed and can
be obtained only from a git repository. The command to download
them is: git clone --depth 1
https://gitlab.freedesktop.org/poppler/test.git
testfiles. Then issue: LC_ALL=en_US.UTF-8 ninja test.
One subtest of check_qt6_signature_basics is known to fail.
Now, as the root
user:
ninja install
To install the documentation, run the following commands as
root
:
install -v -m755 -d /usr/share/doc/poppler-24.08.0 &&
cp -vr ../glib/reference/html /usr/share/doc/poppler-24.08.0
Poppler Data
If you downloaded the additional encoding data package, install it
by issuing the following commands:
tar -xf ../../poppler-data-0.4.12.tar.gz &&
cd poppler-data-0.4.12
Now, as the root
user:
make prefix=/usr install
Command Explanations
-D
CMAKE_BUILD_TYPE=Release
: This switch is used to apply
a higher level of compiler optimizations.
-D
TESTDATADIR=$PWD/testfiles
: Tells the test programs
where the auxiliary files are located.
-D ENABLE_QT5=OFF
: This
switch is needed to prevent an error when Qt5 is not installed.
Remove it if you have installed qt5-components-5.15.14.
-D
ENABLE_UNSTABLE_API_ABI_HEADERS=ON
: Installs some old
Xpdf headers required by certain
programs.
-D ENABLE_GTK_DOC=ON
: Use this
parameter if GTK-Doc is installed and you wish to rebuild and
install the API documentation.
-D ENABLE_QT6=OFF
: Use this parameter
if Qt-6.7.2 is not installed.
-D ENABLE_BOOST=OFF
: Use this parameter
if you have not installed boost
(the Splash backend for Qt5 recommends boost).
-D ENABLE_NSS3=OFF
: Use this parameter
if you have not installed nss.
-D ENABLE_GPGME=OFF
: Use this parameter
if you have not installed gpgme.
-D ENABLE_LIBTIFF=OFF
: Use this
parameter if you have not installed libtiff.
LC_ALL=en_US.UTF-8 ninja
test: Runs the test suite. The environment variable
LC_ALL=en_US.UTF-8 is only needed if the default locale does not
include UTF-8.
