2010-11-20 19:24:30     opencv library for blackfin

Message: 96064   

 

I am trying to cross compile opencv library with uclinux for blackfin processor.

 

I am using the opencv source code "opencv-1.1pre1.tar.gz". I used the following commands from the source directory of opencv

 

> ./configure --host=bfin-uclinux --without-octave --without-gtk --without-v4l --without-carbon --without-quicktime --without-1394libs --without-ffmpeg --without-python --without-swig --enable-static --disable-shared --disable-apps --disable-openmp LDFLAGS=-mfast-fp \CC=bfin-uclinux-gcc-4.1.2 \CXX=bfin-uclinux-g++-4.1.2 \CPPFLAGS=-I/usr/include

 

> make 

 

Until make, everything goes well, But after "make install", i get the following error

 

> sudo make install.

you do not do anything as root.  it makes no sense to install cross-compiled packages into /usr/local/.

 

please integrate your lib into the uclinux-dist like normal and let it manage the install to the rootfs.
