I am trying to compile OpenCV 1.0.0 for  uClinux R06.

The configuration command I am using:

./configure --build=i686-pc-linux-gnu --host=bfin-uclinux LDFLAGS="-L/home/....../practice/uclinux/uClinux-dist/lib/ --without-gtk

However, the log after configure shows that it hasn't been able to find packages like libjpeg (present in the above directory specicfied during ./configure)

Also upon executing make, I get errors of failed dependencies of functions apparently defined in math.h. Thus it seems like files like math.h also arent being included.

the latest release is 2008R1.5.  it supports staging libraries as documented here:

http://docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:existing_libraries#using_libs_in_external_applications

otherwise you need to handle all of the library/includes yourself

Thanks a lot.

One more question: Is the uClinux kernel supposed to be compiled in order to execute the

make vendor_staging_install

the Linux kernel does not matter to staging libraries

the staging_install target will only install the libraries you've already built in uclinux-dist

Thanks.

What is the exact procedure to build individual libraries in the uClinux dist?

Pardon me, but I am very new to the whole linux, uClinux as well as Blackfin environments

you want to compile existing ones or add your own ?

if you want to compile existings ones, just select it in the menuconfig settings and then run `make`

Dear Ashwin.

I'm trying use OpenCv in uClinux too. I compiled the OpenCv but it doesn't work...   I'll see the parameter that I use in configure and I'll post here...

Which hardware plataform do you use? I'm using the BF537-STAMP-BOARD.
