Notes on OSX port

GCompris on OSX.

Compilation modification

• add sdl.m4 into acinclude.m4. Needs cleaning, sdl.m4 is not used on OSX !
• add #define NO_IMPORT_PYGOBJECT 1 before #include <pygobject.h>
• Change on SDL/SDL_mixer détection. My opinion is to use OSX frameworks. SDL_mixer framework looks broken for now: missing SDL/ in headers #include (use of SDL framework.. ).
• Change #include for SDL* frameworks if we use them.
• suppress $LIBICONV in gcompris LDADD (multiply defined _locale_charset).
• Add check if argv[0] is full path beginning with /. If yes, get the install prefix from it. Usefull for GCompris.app relocatable OSX bundle.
• GNUcap detection looks broken:

gcompris: Dialog=Impossible de trouver le logiciel de simulation électrique « GnuCap ».
Vous pouvez le télécharger à l'adresse:
<http://geda.seul.org/tools/gnucap/>
Pour être détecté, l'exécutable doit être installé dans /usr/bin/gnucap ou /usr/local/bin/gnucap.
Vous pouvez tout de même utiliser cette activité pour construire des schéma électriques mais vous ne pourrez pas les simuler.

J'ai ajouté un test au bon endroit.

• Même genre de test pourGNUchess.

Native Gtk

• Works, but with bugs. Some small images abd some colors looks bad. The color selector is broken.
• Cairo/GTK are not frameworks. GTK is not relocatable (relocatable only on windows).
• Wait a better version.
• OSX support status on gtk-devel.
• Gtk OSX Using imendio script

X11/GTK

• Check inkscape and Gimp.app way.
• Gimp.app links to a Platypus script (ScriptExec). inkscape seems use the same solution.
• Inkscape launch a shell script set lot of environnement variables to locate correctly libs.

script launcher (Platypus)/ScriptExec

• Platypus create an exec application (a running .app bundle in fact) with a cocoa executable script launcher in Contents/MacOS and the script to run in Contents/Resources.
• Gimp.app uses a modified version (why?). Anyway this version does not compile with my xcode.
• Inkscape seems have a already modified version with right extension (xcodeproj). To be tested Direct compilation fails too. Needs to suppress libstdc++.a from External resources. Builds ok and works ok without it.
• This Xcode compilation gives the bundle executable. (From here: copy ScriptExec/build/ScriptExec.app/Contents/MacOS/ScriptExec to Gimp.app/Contents/MacOS/Gimp )
• Need to set XCode to Deployment target, for the compilation to be complete.

Notes on launch script

• The PANGO_RC_FILES need no " around the filenmae. Looks as a modifiction with svn pango.
• The actuyal Gimp.app script looks better: Uses /tmp instead of .gcompris-etc to put the modified files at launch.
