Angstrom && opencv build error

Hi all,
I'm trying to have opencv for the beagleboard.
I get angstrom toolchain from http://www.angstrom-distribution.org/narcissus/
and I checked the opencv library but I can't find the library to use
so I decided to cross compile opencv.

The opecv version I use is 1.0 but 2.0 is the same.

this is the procedure I followed:

cd opencv-1.0.0
export CXX=/usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-g++
. /usr/local/angstrom/arm/environment-setup
./configure --host=arm-linux --without-gtk --without-highgui --without-
v4l --without-carbon --without-quicktime --without-1394libs --without-
ffmpeg --without-python --without-swig --disable-apps
make

but I get this error:

/bin/sh ../../libtool --tag=CXX --mode=link arm-angstrom-linux-gnueabi-
g++ -Wall -fno-rtti -pipe -O3 -fomit-frame-pointer -o libcxcore.la
-rpath /usr/local/lib -no-undefined -version-info 1:0:0 dummy.lo
lib_cxcore.la -lpthread -ldl -lm
libtool: link: cannot find the library `' or unhandled argument `/'
make[3]: *** [libcxcore.la] Error 1

Can you help me?

Thanks

Have someone compiled successfully opencv library for beagleboard?

I did it on the beagleboard itself using ubuntu - worked flawlessly.

Yes I managed to compile successfully natively on the BeagleBoard. I
posted my process here (http://tirokartblog.wordpress.com/2010/09/08/
qr-codes-decoded-on-the-beagleboard/ ) as part of the process of
getting a QR code decoder working.

Thanks,
but I didn't find how to cross compile opencv in your link.

6

It was done natively so there is no cross compiling involves

7

No compilation needed to get qr decode working:

Isn't that always the way! Thanks for that - interesting to see it
working with the LI camera module too.
