EDIT:
I finally released a dingux toolchain for compiling GTK2 apps, and a rootfs. You can test the rootfs with gtkperf. You can find all in the downloads section.

Good GTK coding!

P.S.: once again thanks to vimrc!

*****************************************

I am trying to compile GTK2 over dircetfb.

To compile tslib, autoconf and libtool are needed, so i have installed them on my ubuntu system:
sudo apt-get install autoconf libtool

the ingenic sources are available here:
ftp://ftp.ingenic.cn/3sw/01linux/05apps/gtk/gtk-directfb-jz.tar.bz2

after having unpacked the archive you can go to the scripts subdirectory and set the right prefix in the build script. The following libraries compile good out of the box:

- tslib      -> OK
- libxml2   -> OK
- freetype   -> OK
- fontconfig   -> OK
- directfb   -> OK

to compile them, go to the build subdir, then:
../script/build

Glib didn'tt work, so I have taken the version compiled by vimrc, as explained here:
http://boards.dingoonity.org/dingux-development/how-to-run-debian-mipsel-application-on-dingux-%28again-thanks-dan!%29/msg3297/#msg3297
the archive is here:
http://bossninja.googlepages.com/gettext_glib2.tar.bz2
unpack the package and merge with the toolchain

sudo apt-get install libglib2.0-dev

----> change prefix in /opt/mipsel-linux-uclibc/lib/pkgconfig/glib2.0.pc , gobject.pc , gmodule.pc, gmodule-export , gmodule-no-export, gthread
----> change paths in libglib.la libgobject.la libgmodule.la libgthread.la
- atk      -> OK

cp -r /opt/mipsel-linux-uclibc/usr/lib/pkgconfig /opt/mipsel-linux-uclibc/lib/

- cairo      -> OK

----> cp all files in /opt/mipsel-linux-uclibc/include/cairo to /include

I am stuck in compiling pango, getting a lot of undefined references of function contained in libpangocairo.so . In attachment the log of the make issues. In the other attachment, there are also the scripts i made to compile separately every single library (zip archive renamed to pdf). I  Hope someone can give me some good hint.

Hi, batman52,

The problem is pango depends on the cairo, if you add the libcairo.so, you can kill these undefined references.

or you can simply get my complied cairo lib to pass it.
http://bossninja.googlepages.com/libcairo1.8.8.rar

It seems you miss the pixman?  For the pkg path, you can always use
export PKG_CONFIG_PATH=/opt/mipsel-linux-uclibc/usr/lib/pkgconfig/


Success!

Oh, if you have cairo, it's easier. The following part is from your log:

mipsel-linux-gcc -g -O2 -Wall -o .libs/cairosimple cairosimple.o  -L/opt/mipsel-linux-uclibc/lib -L/opt/mipsel-linux-uclibc/usr/lib ../pango/.libs/libpango-1.0.so ../pango/.libs/libpangocairo-1.0.so /media/Data/dingoo/dingux/dev/gtk-directfb/build/pango-1.16.4/pango/.libs/libpangoft2-1.0.so ../pango/.libs/libpangoft2-1.0.so /media/Data/dingoo/dingux/dev/gtk-directfb/build/pango-1.16.4/pango/.libs/libpango-1.0.so /opt/mipsel-linux-uclibc/lib/libgobject-2.0.so /opt/mipsel-linux-uclibc/lib/libgmodule-2.0.so /opt/mipsel-linux-uclibc/lib/libglib-2.0.so /opt/mipsel-linux-uclibc/lib/libintl.so -lc /opt/mipsel-linux-uclibc/lib/libfontconfig.so /opt/mipsel-linux-uclibc//lib/libxml2.so -ldl /opt/mipsel-linux-uclibc/usr/lib/libiconv.so /opt/mipsel-linux-uclibc/lib/libfreetype.so -lz -lm -Wl,--rpath -Wl,/opt/mipsel-linux-uclibc/lib -Wl,--rpath -Wl,/opt/mipsel-linux-uclibc/usr/lib -Wl,--rpath -Wl,/opt/mipsel-linux-uclibc//lib

But this command missed the libcairo.so, so if you add it, like this:

mipsel-linux-gcc -g -O2 -Wall -o .libs/cairosimple cairosimple.o  -L/opt/mipsel-linux-uclibc/lib -L/opt/mipsel-linux-uclibc/usr/lib ../pango/.libs/libpango-1.0.so ../pango/.libs/libpangocairo-1.0.so /media/Data/dingoo/dingux/dev/gtk-directfb/build/pango-1.16.4/pango/.libs/libpangoft2-1.0.so ../pango/.libs/libpangoft2-1.0.so /media/Data/dingoo/dingux/dev/gtk-directfb/build/pango-1.16.4/pango/.libs/libpango-1.0.so /opt/mipsel-linux-uclibc/lib/libgobject-2.0.so /opt/mipsel-linux-uclibc/lib/libgmodule-2.0.so /opt/mipsel-linux-uclibc/lib/libglib-2.0.so /opt/mipsel-linux-uclibc/lib/libintl.so -lc /opt/mipsel-linux-uclibc/lib/libfontconfig.so /opt/mipsel-linux-uclibc//lib/libxml2.so  /opt/mipsel-linux-uclibc//lib/libcairo.so -ldl /opt/mipsel-linux-uclibc/usr/lib/libiconv.so /opt/mipsel-linux-uclibc/lib/libfreetype.so -lz -lm -Wl,--rpath -Wl,/opt/mipsel-linux-uclibc/lib -Wl,--rpath -Wl,/opt/mipsel-linux-uclibc/usr/lib -Wl,--rpath -Wl,/opt/mipsel-linux-uclibc//lib

You can kill the error. (:


Currently I am using the Pango from Openwrt, but it's very painful to compile it. I met hundreds of problems including this problem..., so I am sure you can use that way to pass it. Now I can compile it successfully but I am stuck by the "Make install", I guess I chose a bad version, maybe you can pass it.

It took me about 4 hours to kill the pango's problem, I have to go out and eat sth... (:

i had to adda copy of libpng12.pc

cp  /opt/mipsel-linux-uclibc/usr/lib/pkgconfig/libpng12.pc  /opt/mipsel-linux-uclibc/lib/pkgconfig/

Then, still errors in compiling GTK...

sorry... but i'm really a noob...
where am i supposed to set that define?

you can easily download the one from ingenic, too if you like...

EDIT: forget it, i found
I had to apply that change in: gdk/directfb/gdkdrawable-directfb.c, gdk/directfb/gdkimage-directfb.c

wow! It's very good news! You really, really, really rock!
I think that we have to automate the building script now, in order to make it easier to replicate this. I have an important meeting today, so i think i can work on it tomorrow.

BTW: i am not sure i understood correctly but could the directfb issue solve problems with osd in mplayer too? Why you say you can't create the /opt folder? it's just a question of modify the rootfs as far as i can understand.

I feel really happy with this! ^_^

Yep, it's a good idea to modify the rootfs, but I think it's better to create a /lib/gtklib/ as the timidity
library without changing the default rootfs.

But how do we do with symlinks? We should make a script to mount a romfs with gtk libs before launching avery single GTK app: i feel like it wouldn't be very comfortable.

It looks like (if we get it working alright) it would be better to include it all into the default rootfs, let's ask booboo too anyway.

@mirco:
our discussion rise again after having read your article  ^_^.

I started fron the ingenic sources, because... it was the only that i knew should have worked.  The ingenic stuff i used anyway is slightly different from what used vimrc.

I still haven't looked at openwrt things because i still can't use svn. Maybe you're right we shold switch to it if it works (no more need of flaky support by ingenic).

@mirco,

Fancy to meet you here! I met several annoying problems when I compiled the latest pango, so I downgraded
its version to pass these error, just wanna know if my direction was right. Yes, now we have known gtk+ works
well, I will try to upgrade its version anyway.  (:

@batman52,

I agree with you. Maybe fbreader is promising to attract others into the GTK+ world. (;

Next, a port of apvlv or zathura (vim-like pdf readers)?

I think it's still a bit early for requests.

I believe the next step is to automate the compilation of GTK (I'll start working on it this eve).
BTW: i'll try using openwrt sources with mirco's patches.

Then, we can release the GTK toolchain (that hopefully will be integrated into the dingux default one).
When this will be achieved, everyone could start port his favourite application.

@Berticus: I'll start with FBreader, because in my experience i find that ebook formats are more suited for small-screen devices like the dingoo. With most pdf you would have to continuosly pan-scan the screen, that is very uncomfortable. Nevertheless i think that a pdf reader is a precious tool, so it's in my whishlist too. Anyway there is a plenty of software tools suited to convert pdf-to-anything, most notably calibre (http://calibre.kovidgoyal.net/).
