CompilingMacOsX

Before you start

Note that from version 0.42 of Inkscape a Mac OS X package (in .dmg form) will be available for official releases as well as for development versions. Both can be downloaded from Inkscape's downloads page:

http://www.inkscape.org/download.php

Inkscape for Mac OS X is an X client: it runs under the X Windows System. You will need an X Windows Server installed for it to work. For 10.4.x users, X11 can be installed from your installation DVD. For 10.3.x users, you can get Apple's X Server here:

Compiling Inkscape

Requirements

To compile Inkscape from source you will need:

• Mac OS X 10.3 of 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.

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

Essential 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.

Optional dependencies

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)

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.

Building

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

Many Mac OS applications are distributed in a dmg with a background picture and some basic installation instructions. In order to distribute Inkscape this way you first need to create an .app bundle of Inkscape as described above. Then you need to create a read-write disc image big enough to contain the app bundle:

hdiutil create -size 55m -fs HFS+ -volname "Inkscape" RWinkscape.dmg

This step has only to be done once. For next builds you will just have to reattach the image and copy the new Inkscape .app inside it. To attach the disc image, double click the .dmg or use:

hdiutil attach RWinkscape.dmg 

The second step is to copy everything you need inside the attached disc image (which is available as a white disc icon named "Inskcape" on your Desktop). You need:

• the .app bundle
• an alias to the Applications folder (CTRL+click Applications and select "Make Alias")
• the background picture

Finally you need to improve the appearance of the disc image. First you need to set the background image:

• navigate to the attached disc image with the Finder
• switch the Finder to Icon's view (View > as Icons)
• open the View Options window (View > Show View Options)
• check the radio button to select options for "This window only"
• in the "Background" section, select "Picture" and choose the background picture you just copied in the disc image.

You may want to make the background image file invisible to have a cleaner aspect:

/Developer/Tools/SetFile -a V /Volumes/Inkscape/background.png

The icon of the file should become kind of transparent and you should not see it anymore if you relaunch the Finder. Enventually, arrange the Finder window as you want people to see it. You may want to hide the Finder brushed metal skin to have a smaller window (click the elongated transparent button in the top right corner of the Finder window), fit the window to the background image, move Inkscape's icon to be next to the arrow (you may need to deselect some presentation options in View > Show View Options) and center the window in your screen. You should end up with a window looking like this.

The last step consists in creating a compressed read-only disc image from this read-write disc image:

hdiutil detach /Volumes/Inkscape
DATE=`date "+%Y%m%d"`
hdiutil convert -format UDCO -o Inkscape_$DATE.dmg RWinkscape.dmg 

This creates a smaller disc image with a name like Inkscape_20060424.dmg.

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. To install it you need to

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.
