You can download the latest source distribution via one of the following links:

http://pugixml.googlecode.com/files/pugixml-0.9.zip
http://pugixml.googlecode.com/files/pugixml-0.9.tar.gz

The distribution contains library source, documentation (the manual you're reading now and the quick start guide) and some code examples. After downloading the distribution, install pugixml by extracting all files from the compressed archive.

If you need an older version, you can download it from the version archive.

The Subversion repository is located at http://pugixml.googlecode.com/svn/. There is a Subversion tag "release-{version}" for each version; also there is the "latest" tag, which always points to the latest stable release.

For example, to checkout the current version, you can use this command:

svn checkout http://pugixml.googlecode.com/svn/tags/release-0.9 pugixml

To checkout the latest version, you can use this command:

svn checkout http://pugixml.googlecode.com/svn/tags/latest pugixml

The repository contains library source, documentation, code examples and full unit test suite.

Use latest version tag if you want to automatically get new versions via svn update. Use other tags if you want to switch to new versions only explicitly (for example, using svn switch command). Also please note that Subversion trunk contains the work-in-progress version of the code; while this means that you can get new features and bug fixes from trunk without waiting for a new release, this also means that occasionally the code can be broken in some configurations.

The easiest way to build pugixml is to compile two source files, pugixml.cpp and pugixpath.cpp, along with the existing library/executable. This process depends on the method of building your application; for example, if you're using Microsoft Visual Studio^[1], Apple Xcode, Code::Blocks or any other IDE, just add pugixml.cpp and pugixpath.cpp to one of your projects.

If you're using Microsoft Visual Studio and the project has precompiled headers turned on, you'll see the following error messages:

pugixpath.cpp(3477) : fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "stdafx.h"' to your source?

The correct way to resolve this is to disable precompiled headers for pugixml.cpp and pugixpath.cpp; you have to set "Create/Use Precompiled Header" option (Properties dialog -> C/C++ -> Precompiled Headers -> Create/Use Precompiled Header) to "Not Using Precompiled Headers". You'll have to do it for both pugixml.cpp and pugixpath.cpp, for all project configurations/platforms (you can select Configuration "All Configurations" and Platform "All Platforms" before editing the option):

It's possible to compile pugixml as a standalone static library. This process depends on the method of building your application; pugixml distribution comes with project files for several popular IDEs/build systems. There are project files for Apple XCode3, Code::Blocks, Codelite, Microsoft Visual Studio 2005, 2008, 2010, and configuration scripts for CMake and premake4. You're welcome to submit project files/build scripts for other software; see Feedback.

There are two projects for each version of Microsoft Visual Studio: one for dynamically linked CRT, which has a name like pugixml_vs2008.vcproj, and another one for statically linked CRT, which has a name like pugixml_vs2008_static.vcproj. You should select the version that matches the CRT used in your application; the default option for new projects created by Microsoft Visual Studio is dynamically linked CRT, so unless you changed the defaults, you should use the version with dynamic CRT (i.e. pugixml_vs2008.vcproj for Microsoft Visual Studio 2008).

In addition to adding pugixml project to your workspace, you'll have to make sure that your application links with pugixml library. If you're using Microsoft Visual Studio 2005/2008, you can add a dependency from your application project to pugixml one. If you're using Microsoft Visual Studio 2010, you'll have to add a reference to your application project instead. For other IDEs/systems, consult the relevant documentation.

It's possible to compile pugixml as a standalone shared library. The process is usually similar to the static library approach; however, no preconfigured projects/scripts are included into pugixml distribution, so you'll have to do it yourself. Generally, if you're using GCC-based toolchain, the process does not differ from building any other library as DLL (adding -shared to compilation flags should suffice); if you're using MSVC-based toolchain, you'll have to explicitly mark exported symbols with a declspec attribute. You can do it by defining PUGIXML_API macro, i.e. via pugiconfig.hpp:

#ifdef _DLL
#define PUGIXML_API __declspec(dllexport)
#else
#define PUGIXML_API __declspec(dllimport)
#endif

pugixml uses several defines to control the compilation process. There are two ways to define them: either put the needed definitions to pugiconfig.hpp (it has some examples that are commented out) or provide them via compiler command-line. Define consistency is important, i.e. the definitions should match in all source files that include pugixml.hpp (including pugixml sources) throughout the application. Adding defines to pugiconfig.hpp lets you guarantee this, unless your macro definition is wrapped in preprocessor #if/#ifdef directive and this directive is not consistent. pugiconfig.hpp will never contain anything but comments, which means that when upgrading to new version, you can safely leave your modified version intact.

PUGIXML_WCHAR_MODE define toggles between UTF-8 style interface (the in-memory text encoding is assumed to be UTF-8, most functions use char as character type) and UTF-16/32 style interface (the in-memory text encoding is assumed to be UTF-16/32, depending on wchar_t size, most functions use wchar_t as character type). See Unicode interface for more details.

PUGIXML_NO_XPATH define disables XPath. Both XPath interfaces and XPath implementation are excluded from compilation; you can still compile the file pugixpath.cpp (it will result in an empty translation unit). This option is provided in case you do not need XPath functionality and need to save code space.

PUGIXML_NO_STL define disables use of STL in pugixml. The functions that operate on STL types are no longer present (i.e. load/save via iostream) if this macro is defined. This option is provided in case your target platform does not have a standard-compliant STL implementation.

	Note
	As of version 0.9, STL is used in XPath implementation; therefore, XPath is also disabled if this macro is defined. This will change in version 1.0.

PUGIXML_NO_EXCEPTIONS define disables use of exceptions in pugixml. This option is provided in case your target platform does not have exception handling capabilities

	Note
	As of version 0.9, exceptions are only used in XPath implementation; therefore, XPath is also disabled if this macro is defined. This will change in version 1.0.

PUGIXML_API, PUGIXML_CLASS and PUGIXML_FUNCTION defines let you specify custom attributes (i.e. declspec or calling conventions) for pugixml classes and non-member functions. In absence of PUGIXML_CLASS or PUGIXML_FUNCTION definitions, PUGIXML_API definition is used instead. For example, to specify fixed calling convention, you can define PUGIXML_FUNCTION to i.e. __fastcall. Another example is DLL import/export attributes in MSVC (see Building pugixml as a standalone shared library).

	Note
	In that example PUGIXML_API is inconsistent between several source files; this is an exception to the consistency rule.
