CompilingMacOsX

Compiling on Mac OS X

Requirements

To compile Inkscape from source you will need:

• Mac OS X 10.3 (Power PC) or higher
• A full unstable fink installation
• Inkscape's source code. You can get the official release source code, a SVN snapshot or a copy of the SVN repository.
• A DarwinPorts install if you want to use inkboard.
• XCode 2.3 on OS X 10.4 (gcc 4.0.1)

You need to install software on which Inkscape depends, using Fink and/or DarwinPorts.

Dependencies

They are necessary for Inkscape to compile. In a Terminal type:

fink install \
        intltool \
        glib2 glib2-dev glib2-shlibs \
        gtk+2 gtk+2-shlibs gtk+2-dev \
        libpng3 libpng3-shlibs \
        libsigc++2 libsigc++2-shlibs \
        gtkmm2.4 gtkmm2.4-dev gtkmm2.4-shlibs \
        libtool14 libtool14-shlibs \
        libxml2 libxml2-shlibs \
        popt popt-shlibs \
        gc gc-shlibs \
        automake1.8

You need version 1.8 of automake 1.8 (and not 1.9, the latest in Fink). Fink installs many packages from source so this is usually long.

You may also need to build popt from source (tested on 10.4): [1]

(Since May 2006, the version of sigc++ required when using gcc 4 is 2.0.12 or greater. For a short time, only 2.0.11 was available in Fink. The latest version of libsigc++2, version 2.0.17, has now been added to fink unstable so everything should compile normally again.)

Optional Features

To enable some additional functionality in Inkscape you might want to install:

• lcms : color management via LittleCMS
• loudmouth >= 1.0 : collaborative whiteboard (only available in DarwinPorts)
• boost >= 1.32 : auto-organisation of connectors
• gnome-vfs
• gnome-print
• xft2

for each of these you need the developement packages as well (the name ends by -dev)

Easy Compile

You can try to download this bash script which automates the processes of updating Inkscape from the svn repository, setting the build environment, building and producing a simple package of Inkscape. Modify it with your favorite text editor in order to set a correct install prefix and to change configuration options.

Check Inkscape source code from svn and copy the script to the base of your local svn repository. Make it executable:

chmod +x makeosx.sh

and then simply run it

./makeosx.sh

If something doesn't run smoothly, refer to the indications underneath.

Setting the build environment

Fink's hierarchy is not searched for libraries by default. Therefore, before the configuration starts, some environment variables need to be set. The environment variables are presented in bash syntax here. You can create a file named set_env_variables.sh and copy/paste this inside:

FINK="/sw"
export CFLAGS="-O3 -Wall"
export CXXFLAGS="$CFLAGS"
export CPPFLAGS="-I$FINK/include"
export LDFLAGS="-L$FINK/lib"
export CPATH="$FINK/include"
export PATH="/usr/X11R6/bin:$PATH"
export LIBRARY_PATH="/usr/X11R6/lib:$FINK/lib"
export PKG_CONFIG_PATH="$FINK/lib/pkgconfig"

In addition, you must make sure that Inkscape is compiled with the compiler version that Fink uses, otherwise Inkscape will not link properly. To determine which compiler to use type:

head -n 5 $FINK/etc/fink.conf | grep "Distribution"

If your fink distribution is 10.4 add:

export CC="gcc-4.0"
export CXX="g++-4.0"

to set_env_variables.sh, else (10.3, 10.4-transitional) add:

export CC="gcc-3.3"
export CXX="g++-3.3"

You can also use ccache (fink install ccache) to speed up the compilation a bit. To do so, modify the compiler lines accordingly:

export CC="ccache gcc-??"
export CXX="ccache g++-??"

Eventually, open a Terminal and, in the directory where you created the file set_env_variables.sh, type:

bash; source set_env_variables.sh

Configuring

You might need to build the configure script first (if you compile Inkscape for the first time). Cd to Inkscape's source directory and run:

./autogen.sh

Then run the configure script:

./configure --prefix=/path/to/build/products/ --enable-osxapp

The --prefix option sets the directory where the build products are placed. It must be somewhere you have write access to. The option --enable-osxapp allows you to package Inkscape into an .app bundle in order to access it like a regular OS X application. Remove this option if you only want to build Inskscape, not to package it afterwards. Of course you can add here classic configuration options such as --enable-lcms for color management or --enable-inkboard for whitboard functionality.

Starting the Build

Piece of cake:

make
make install

Packaging Inkscape into an .app bundle

Creating the .app and a simple .dmg

Assuming that you have used the --enable-osxapp option during configure, the process is fully automatized. You just have to open a Terminal, cd to Inkscape's sources directory and type:

cd packaging
./osx-app.sh -s /path/to/build/products/bin/inkscape ../Info.plist macosx

The -s options produces an app bundle stripped of debugging information (which is therefore smaller). Omit this option if you want to keep debugging info.

Either way, this creates two files in current directory: Inkscape.app that you can copy to your Applications directory and Inkscape.dmg for distribution.

Creating a more complete .dmg

The steps that used to comprise this section have since been integrated into the official Inkscape.app build script, refered to above.

Enabling python effects

Many "effects" in the Effect menu of Inkscape use python as a scripting language. Mac OS X ships with python but not with pyXML which is needed by Inkscape effects. You can install a binary version downloadable with the developement builds of Inkscape:

http://inkscape.modevia.com/macosx-snap/?M=D

Or you can install it from source:

1. download the source code from sourceforge
2. unpack the .tar.gz file
3. cd into the newly created directory
4. set the variable MACOSX_DEPLOYMENT_TARGET to the number of your operating system (10.3 for Panther, 10.4 for Tiger. It probably won't work on previous systems). In bash syntax this means typing:

   export MACOSX_DEPLOYMENT_TARGET=10.?

5. move the python files and build C extensions

   python setup.py build

6. install (the install is system wide so you need administrator rights)

   sudo python setup.py install

   and type your password.
