looks good!

Now try to start the irex stuff...

As to pangox and pangoxft, I didn't notice that these two libs did not exist. I will check what's wrong.
Thanx so much. You really gave me a big hand.

Added:
It seems that newer pangox and pangoxft are not compatible with fontconfig and freetype on iLiad. Therefore, pangox and pangoxft wasn't built. I will try to replace them, or downgrade to pango1.20.

Added 2:
I was wrong. There is nothing incompatible between Pango and freetype. It's solved after I gave correct include and lib path to ./configure.

It's totally working now. I have removed gtk-related libs under /usr/lib and cf is still bootable.
Here is the complete gtk lib package. Put the "local" dir in /usr. Copy local/etc/pango and local/etc/gtk-2.0 to /etc, overwrite the original. It's all.
Thanx hansel, jharker, and Antartica. Your knowledge helps me.

Added:
In the package, local/bin and some dir in local/share/locale might be unneeded.

Added 2:
The following files in /usr/lib is safe to remove.

glib-2.0
gtk-2.0
pango
libatk-1.0.so.0
libatk-1.0.so.0.1011.0

Let's compare memory usage under original iLiad (GTK+2.6) and GTK+2.14.7:

What is the difference in disk usage?

If the new libs are not much bigger than the old ones, and if you can provide a clean recipe to build all those libs form their sources, and check that everything keeps running fine, this might be ready for inclusion in the next IliadOS!

PS: you can strip the libs without problem to make them smaller.
PPS: I tried to give you some karma, but the system insists "You must spread some Reputation around before giving it to ericshliao again."

If not stripped, disk usage is roughly 15mb more. As to compile, I didn't apply any patch to the source code. Everything just went fine after I setup proper pkg-config environment in Scratchbox.

That's beyond my current knowledge. I have to do some study.

Thanx for your consideration. Your help is already so wonderful.

[ericshliao]

This is a package of stripped libs. Disk usage difference between GTK+2.6 and GTK+2.14.7 should be no more than 3mb. From the tiny size difference, I guess iRex didn't rip any source code, they just stripped the shared objects.

Besides GTK+related libs, I also upgraded some other libs (also put in the package). Leave them in /usr/local/lib is safe. If you want to try, just remove their older version in /usr/lib. But /usr/lib/libexpat should not be removed.

These libs are working perfectly on my iLiad. ipdf, mobi reader, newLister, fbreader 0.10.7, and my homebrew apps have been tested to run with these libs.

[ericshliao]

I have put all the new libs into iLiad root partition, and removed their respective old version. My iLiad works like a charm.
To make more storage space in root partition, removing /usr/lib/mozilla-minimo is required. Putting /usr/local/lib in /mnt/free and make a symbolic link should be a workaround, too.
Since I have an update to date bootable cf, I guess I won't need to reflash my iLiad for a long time. If iLiad fails to run, booting from cf and restoring damaged files should be enugh. I hope so.

Great achievement! . Congrats.

Hope that these updated libraries can go into the iliad OS soon .

[ericshliao]

This is a package of newer libs that is ready to be unpacked in iLiad root partition (or bootable CF). After unpacked, it will occupy 20mb, so please make sure there is enough space in root partition.
I extracted the package from my bootable CF, which is identical to iLiad root partition. So, I think it should be working for everyone. To be cautious, however, I would suggest applying the package on a bootable CF first.

Package content:

/etc/fonts -- will replace the original
/etc/pango -- will replace the original
/usr/local -- new libs.
README.txt -- a list of libs should not be removed from /usr/lib. Others are safe to delete.

I made an update to the package because I forgot to remove unneeded fils in /etc. It's clean now.
