To build from source for Linux or other UNIX/UNIX-like systems, it is generally sufficient to download just the
|
|
source `qpdf-<version>.tar.gz` file.
|
|
|
|
Windows Binaries
|
|
|
|
You can download Windows binaries that are statically linked with qpdf's external dependencies and use the OpenSSL
|
|
crypto provider. There are several options:
|
|
|
|
* For Windows installers, you can download the `.exe` file for a traditional installer that allows relocation, or you
|
|
can download the `.zip` file which you can unzip to any location. Note that the `msvc` executables perform slightly
|
|
better than the `mingw` executables.
|
|
|
|
* `qpdf-<version>-bin-msvc64.exe` - Use this for 64-bit Windows systems. This is the highest performance Windows
|
|
release. It is usually the best choice for using qpdf from the command line. It is also the right choice if you are
|
|
building non-Debug code for 64-bit systems using a recent version of Microsoft Visual C++.
|
|
|
|
* `qpdf-<version>-bin-mingw64.exe` - This is a 64-bit version built with mingw. Use this for 64-bit Windows systems if
|
|
you want development libraries that work with the 64-bit version of mingw. If you are dynamically loading qpdf from
|
|
the DLL, this version has fewer DLLs than the msvc version and does not require a Visual C++ runtime DLL. Unlike with
|
|
the MSVC releases, it is possible to link a debugging build with mingw against non-debugging libraries built with
|
|
mingw.
|
|
|
|
* `qpdf-<version>-bin-msvc32.exe` - This is a 32-bit version built with MSVC. Use this if you need to run qpdf on a
|
|
32-bit system or if you are building 32-bit executables in non-Debug mode with Microsoft Visual C++. The 32-bit
|
|
executables will work on 64-bit systems as well and are capable of working with files larger than 2 GB.
|
|
|
|
* `qpdf-<version>-bin-mingw32.exe` - This is a 32-bit version built with mingw. It will work on 32-bit or 64-bit systems
|
|
and can handle files larger than 2 GB.
|
|
|
|
Linux Binaries
|
|
|
|
Virtually all Linux distributions include packages for qpdf. There is also a PPA for Ubuntu
|
|
at https://launchpad.net/~qpdf/+archive/ubuntu/qpdf that includes the latest version of qpdf for recent versions of
|
|
Ubuntu. However, there are some downloads available for Linux as well.
|
|
|
|
* `qpdf-<version>-x86_64.AppImage` - If you'd like to run the latest version of qpdf as
|
|
an [AppImage](https://appimage.org/), you can download this. This is a self-contained executable that you make
|
|
symlink `qpdf` to and run on most reasonably recent Linux distributions. See README-appimage.md in the qpdf source
|
|
distribution for additional details, or run the AppImage with the `--ai-usage` argument to get help specific to the
|
|
AppImage.
|
|
|
|
* `qpdf-<version>-bin-linux-x86_64.zip` - This is not intended to be an end-user distribution. It is a (nearly)
|
|
stand-alone Linux binary, built using an Ubuntu LTS release. It contains the qpdf executables and shared libraries as
|
|
well as dependent shared libraries that would not typically be present on a minimal system. This can be used to
|
|
include qpdf in a minimal environment such as a docker container. It is also known to work as a layer in AWS Lambda
|
|
and was initially created for that purpose. The executables have their runpath set to looks for the qpdf library
|
|
in `../lib` relative to the location of the executables, which makes this distribution relocatable.
|
|
|
|
Windows Build Support
|
|
|
|
If you are building on Windows and want to use pre-built external static libraries, you should obtain current versions
|
|
from https://github.com/qpdf/external-libs/releases. The `external-libs` directory contains older versions that will not
|
|
work with qpdf versions >= 10.0.2. Please see README-windows.md in the qpdf source distribution. The libraries from this
|
|
distribution will not work with a Debug build with MSVC.
|
|
|
|
Documentation
|
|
|
|
* `qpdf-<version>-doc.zip` - This is a downloadable version of the qpdf manual. An online version is hosted
|
|
at https://qpdf.readthedocs.io.
