----

Compiling Inkscape on Windows 64-bit works similar to [[Compiling Inkscape on Windows|compiling Inkscape on Windows 32-bit]] where you can find additional information.

This page only describes the basic steps that are required while highlighting the differences compared to a 32-bit build.

== Requirements ==
=== MinGW-w64 ===

Get [http://mingw-w64.org/ MinGW-w64] which contains the necessary GNU developer tools to build Inkscape on Windows.

You have to download a version that is configured for building native win64 applications with ''win32 threading model'' and ''SEH exception handling'', to ensure compatibility with the inkscape-devlibs64.

A matching build based on GCC 5.3 can be downloaded [https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/5.3.0/threads-win32/seh/ here]. The exact version used for building the inkscape-devlibs64 is [https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/5.3.0/threads-win32/seh/x86_64-5.3.0-release-win32-seh-rt_v4-rev0.7z/download MinGW-w64 x86_64-5.3.0-release-win32-seh-rt_v4-rev0.7z].

=== CMake ===

CMake is a Cross-Platform buildsystem generator similar to autotools. It generates '''makefiles''' to be processed by '''make'''.
Get CMake from the [https://cmake.org/ official website cmake.org]. As of writing [https://cmake.org/files/v3.5/cmake-3.5.2-win32-x86.msi version 3.5.2] is the most recent version.

=== Inkscape development libraries for Windows 64-bit ===

Get the [https://code.launchpad.net/inkscape-devlibs64 inkscape-devlibs64] which include pre-compiled binaries of all Inkscape dependencies.

To checkout via Bazaar use the command
<pre>bzr checkout --lightweight lp:inkscape-devlibs64 C:\devlibs64</pre>
The <code>--lightweight</code> switch ensures that you only have to download the latest version of all binaries, <code>C:\devlibs64</code> is the folder you want them to be downloaded to.

See also [[Inkscape Devlibs 64-bit]] ''(only relevant if you want to update the development libraries)''

=== Inkscape source code ===

Get the [https://launchpad.net/inkscape Inkscape source code] from launchpad

To checkout via Bazaar use the command
<pre>bzr checkout lp:inkscape C:\inkscape</pre>

See also additional information on [[Compiling_Inkscape_on_Windows#Obtaining_Inkscape_source_code|obtaining Inkscape source code]] and [[Working with Bazaar|working with Bazaar]].

== Building ==

=== Environment variables ===

Edit the file <code>mingwenv.bat</code> in the root directory of the Inkscape source to match you local paths. Most importantly the two lines
<pre>
IF "%DEVLIBS_PATH%"=="" set DEVLIBS_PATH=c:\devlibs64
IF "%MINGW_PATH%"=="" set MINGW_PATH=C:\mingw64
</pre>
should point to the folders containing MinGW-w64 and the inkscape-devlibs64.

Whenever you want to build Inkscape open a command prompt (<code>cmd.exe</code>), change into the root directory of the Inkscape source and execute <code>mingwenv.bat</code> to set environment variables.

=== Compiling build tool ===

Compile <code>btool</code> (the command line tool that handles the actual build) using
<pre>g++ buildtool.cpp -o btool -fopenmp</pre>

=== Compiling Inkscape ===

Use <code>btool</code> to compile Inkscape compile  and create the distribution directory:
<pre>btool -file build-x64.xml -j 2</pre>
The file <code>build-x64.xml</code> contains the necessary instructions for creating a standard 64-bit build.<br>
If you want to make a GTK+ 3 build use <code>build-x64-gtk3.xml</code> instead (please note that GTK+ 3 builds are experimental and not ready for production yet).

The <code>-j</code> switch allows to instruct btool to use multiple parallel threads to speed up compilation (e.g. 2 in the example above).

=== Compiling Inkscape using CMake ===

Go to source code directory.

Create the output directory, where the intermediate output goes to.
<pre>
mkdir build
cd build
</pre>

Create the makefiles using CMake.
<pre>cmake .. -G "MinGW Makefiles"</pre>

Start the build proccess. The INkscape.exe will be in build/bin directory afterwards.
<pre>mingw32-make -j 2</pre>

Collect all the needed files and create a selfcontaing directory. ''This currently does not work as with btool.''
<pre>mingw32-make DISTDIR=mydir install</pre>
See [http://stackoverflow.com/questions/11307465/destdir-and-prefix-of-make this article] in stackoverflow about the difference in DISTDIR and PREFIX of make.
