Compiling xpdf
--------------
Xpdf is written in C++ (with a little bit of C). It should work with
any ANSI-compliant C++ and C compilers. The systems and compilers
it's been tested with are listed on the xpdf web page.
Xpdf requires the Qt toolkit. The non-GUI command line tools do not
use Qt.
The following notes give specific instructions for compiling on
different systems.
*********************
*** Linux, OS X ***
*********************
* Make sure you have the following installed:
- CMake 2.8.8 or newer
- FreeType 2.0.5 or newer
- Qt 4.8.x or 5.x (for xpdf only)
- libpng (for pdftoppm and pdftohtml)
- zlib (for pdftoppm and pdftohtml)
If Qt isn't found, the GUI viewer (xpdf) won't be built, but the
command line tools will still be built.
* Create a build directory. These instructions assume that you create
a directory called "build" under the top-level xpdf source
directory, but the build directory can be anywhere you like. Create
the directory and cd into it:
cd ..../xpdf-X.YY
mkdir build
cd build
* Run cmake:
cmake -DCMAKE_BUILD_TYPE=Release {other options - see below} ..
If your build directory isn't under the source, use the full path to
the source directory:
cmake -DCMAKE_BUILD_TYPE=Release {other options} ..../xpdf-X.YY
* If cmake doesn't find FreeType, you can set FREETYPE_DIR to point to
the FreeType install directory. Add this to the cmake command line:
-DFREETYPE_DIR=/opt/freetype
Cmake will look for ${FREETYPE_DIR}/include.
You can also set the FreeType library location with:
-DFREETYPE_LIBRARY=/opt/freetype/lib/libfreetype.so
* If cmake doesn't find Qt, make sure qmake is on your executable
search path.
* To change the xpdf install directory, use:
-DCMAKE_INSTALL_PREFIX=/opt/xpdf
If you're familiar with autoconf, this is similar to the "--prefix"
option.
* Other configuration options are:
-DSPLASH_CMYK=ON
Enable CMYK rasterization support.
-DA4_PAPER=ON
Switches the default paper size for PostScript output (xpdf
and pdftops) to A4. The default is Letter size.
-DNO_TEXT_SELECT=ON
With this option, xpdf will not copy text. (This is only
useful on closed systems where the user can't get at the PDF
file directly.)
-DOPI_SUPPORT=ON
Enables support for generation of OPI (Open Prepress
Interface) comments with pdftops.
-DMULTITHREADED=0
Disables multithreading, which also disables building the GUI
viewer (xpdf). This does not affect the command line tools.
Disabling multithreading should only be necessary if you're
building with a compiler other than gcc, clang, or Microsoft
Visual Studio.
-DSYSTEM_XPDFRC="/etc/xpdfrc"
Look for a system-wide xpdfrc config file in this directory.
-DCMAKE_DISABLE_FIND_PACKAGE_Qt4=1
-DCMAKE_DISABLE_FIND_PACKAGE_Qt5Widgets=1
Do not search for the Qt4/Qt5 libraries. This will disable
building the GUI viewer (xpdf).
-DCMAKE_C_FLAGS="..."
-DCMAKE_CXX_FLAGS="..."
Set additional options to pass to the C and/or C++ compilers.
-DCMAKE_EXE_LINKER_FLAGS="..."
Set additional options to pass to the linker.
-DCMAKE_INSTALL_BINDIR
Set the bin directory, relative to CMAKE_INSTALL_PREFIX
(typically "bin").
-DCMAKE_INSTALL_MANDIR
Set the man directory, relative to CMAKE_INSTALL_PREFIX
(typically "man" or "share/man").
* Build:
make
This will build the executables in the build directory:
xpdf/xpdf
xpdf/pdftops
xpdf/pdftotext
xpdf/pdftohtml
xpdf/pdfinfo
xpdf/pdffonts
xpdf/pdfdetach
xpdf/pdftoppm
xpdf/pdftopng
xpdf/pdfimages
xpdf-qt/xpdf
* If desired, install the binaries and man pages:
make install
If you want to run a quick test, there is a tiny PDF file included
with xpdf, as misc/hello.pdf .
*****************
*** Windows ***
*****************
The Windows build procedure is essentially the same as for Unix. If
building with cygwin, the procedure is identical to Unix.
If building with Visual Studio:
* Make sure you have CMake, FreeType, libpng, and zlib installed.
* You'll need to set the FREETYPE_DIR variable to point to your
FreeType installation, CMAKE_INCLUDE_PATH to point to your libpng
includes, CMAKE_LIBRARY_PATH to point to your libpng library, and
ZLIB_ROOT to point to your zlib installation.
cmake -G "NMake Makefiles"
-DCMAKE_BUILD_TYPE=Release
-DFREETYPE_DIR="c:/software/freetype"
-DCMAKE_INCLUDE_PATH="c:/software/libpng"
-DCMAKE_LIBRARY_PATH="c:/software/libpng"
-DZLIB_ROOT="c:/software/zlib"
..
* Build:
nmake
