Last Friday, November 11th, i have opened a enhancement bug in gnome bugzilla with the patch containing all the modifications necessary to make Gnumeric run on Maemo platform. Today, Monday November 14th, i received the notification that the patch was accepted and now the code is part of Gnumeric mainstream (see the release notes). Thanks to all gnumeric community and Jody Goldberg that commited the patch and helped me a lot to solve the problems i have faced.
For now on, to compile Gnumeric on Maemo platform, just download the source code (at this moment, the last stable version is 1.6.1) and configure it with --enable-hildon option.
If everithing goes fine, by the end of this week we may have the debian packages available to install in the Nokia 770. w00t!
Now, some pics for screenshot lovers. ;)
