Build for OpenEmbedded
OpenEmbedded is a flavour of Linux used on some embedded computers. You need to cross-compile for the platform, having built the compiler. These notes are very old !
If you do not want to compile these yourselves, here are packaged binaries
for OpenEmbedded distributions. These were built using a Gumstix running
the Ångström distro and install vips & nip2 7.20.7 (latest version
at the time of writing) using the /usr prefix. These are quite minimal
and do not link against many of the optional libraries like FFTW.
These were generated following the instructions outlined here: http://handhelds.org/moin/moin.cgi/BuildingIpkgs?action=highlight&value=BuildingIpkgs
Having setup the OE environment configure VIPS src (I use an alias to remind me its:
/usr/src/oe/tmp/deploy/glibc/addons/arm-angstrom-linux-gnueabi-angstrom-gumstix-custom-connex-devshell
As JPEG and TIFF libraries are pretty much essential they need building/cross-compiling locally first then pointing to in the config line
--host option to tell it to use crosscompiler, prefix to point to your special area, stop it using liboil (tricky)
./configure --host=arm-angstrom-linux-gnueabi --prefix=/home/km/armvips --without-liboil
The following were the packages that I had to install to get the build environment setup on the Gumstix.
opkg install flex
opkg install bison
opkg install pkgconfig
opkg install gtk+-dev
opkg install libxml2-dev
opkg install libgthread-2.0-0
opkg install pango-dev
opkg install libpangomm-1.4-dev
opkg install libpng
opkg install libexif-dev
opkg install liboil-dev
opkg install pkgconfig
opkg install m4-dev
opkg install gettext-dev
opkg install g++-symlinks
opkg install bison-dev
opkg install cpp-symlinks
opkg install g++-symlinks
Then the following configure command was used
./configure --prefix=/usr
Somehow the bison installed through opkg (2.3-r1.5) would not work
correctly, so I compiled and installed the newest version of bison (2.4).
Furthermore, vips would not compile unless I commented out im_icc_export
from im_icc_transform.c. This is probably not a final solution as it
could lead to unwanted behavior...
