The program epdfview is PDF reader for handhelds using gtk+ and libpoppler.
Alternatively, evince is in the standard repos, if you don't mind some gnome dependencies - only a few megabytes.
It can be build using the extra DISTRO_EXTRA_RDEPENDS epdfview in build/conf/local.conf.
There is a binary version available for download here (at your own risk). You may need to install libglib-2.0-0 (>= 2.16.4), libcairo2 (>= 1.6.4). Read below how to install the missing packages.
There is a newer version available here.
cd /tmp wget http://www.ginguppin.de/files/epdfview_poppler.tar.bz2 wget http://www.angstrom-distribution.org/feeds/2008/ipk/glibc/armv4t/base/libfreetype6_2.3.6-r0.1_armv4t.ipk opkg install libfreetype6_2.3.6-r0_armv4t.ipk opkg install libpoppler3_0.8.4-r0_armv4t.ipk opkg install poppler_0.8.4-r0_armv4t.ipk opkg install epdfview_0.1.6-r3_armv4t.ipk
Unfortunately the last command still fails missing the packages:
* ERROR: Cannot satisfy the following dependencies for libpoppler-glib3: libglib-2.0-0 (>= 2.16.4) * gtk+ (>= 2.12.11) * libcairo2 (>= 1.6.4) * libpoppler-glib3 (>= 0.8.4) Please note that missing packages is a subjective problem, depending on previous programs that were/weren't installed.
The problem can be fixed searching and downloading the missing packages with KnjMokoOPKG available Here. You may also issue the simple "$ opkg install <name of package>" in terminal once connected to Internet. The next step involves writing: opkg install http://www.ginguppin.de/files/epdfview_0.1.6-r2_armv4t.ipk in Terminal to install the PDF Viewer.
You can find a patched version with an additional page-scrolling feature at http://www.opkg.org/package_193.html.
The most reecent version of libglib-2.0-dev that I could find for armv4 is 2.16.3-r0.
