Migrating OPENCV libraries on Zedboard

Migrating OPENCV libraries on Zedboard
Before doing a lot of porting OpenCV library work, but need to contain the various libraries, need cross-compiling, X264, Jpge, Ffmpge and so on

Note: In the "embedded system hardware and software Collaborative design Practice Guide" in 13 chapters, said the need to close various settings switch, the root cause is that we do not have the corresponding library support, so if we need to use the corresponding library in OpenCV, then we must advance the various libraries cross-compile, into the cross-compiler directory, My cross compiler installation directory/root/codesourcery/sourcery_codebench_lite_for_xilinx_gnu_linux/arm-xilinx-linux-gnueabi/

Then we'll start to cross-compile the following libraries.

1 cross compiler build cross compiler build see: http://blog.csdn.net/xiabodan/article/details/22717175

2 Cross-compiling JPEG 1. Installing the Libtool tool

1.1 Download Libtool Tools libtool-2.2.10.tar.gzhttp://mirrors.ustc.edu.cn/gnu/libtool/

1.2 Tar-xvzf libtool-2.2.10.tar.gz-c/home/xzy/sdb1/jpeg/

1.3 Enter the extracted directory and execute the./configure

1.4 Make

1.5 Make Install

2.JPEG Code Library porting

2.1 Download JPEG source package, select Jpegsrc.v6b.tar.gz http://www.ijg.org/files/

2.2 Unzip the tar jpegsrc.v6b.tar.gz -c/home/xzy/sdb1/jpeg/

2.3 Enter the extracted directory and copy the Libltdl/config/config.sub and config.guess from the libtool-2.2.10 directory to this directory.

2.4 configuration./configure CC=ARM-XILINX-LINUX-GNUEABI-GCC--host=arm-unknown-linux

–prefix=/home/xzy/sdb1/jpeg/jpeg-6b --enable-shared--enable-static

2.5 make

2.6 go to the installation path and create the following directory MkDir bin Lib include man Man/man1, my installation directory is in this directory, note that you have to create these directories, or else make install (tried. )

2.7 make install, and then it's OK.

3 cross-compiling x264 1 Download yasm yasm:http://yasm.tortall.net/download.html decompression Enter the directory to configure the following:

        ./configure--enable-shared--prefix=/root/codesourcery/sourcery_codebench_lite_for_xilinx_gnu_linux/ arm-xilinx-linux-gnueabi/--host=arm-unknown-linux

         Make

         Make install

2 Cross-compiling x264Download x264:ftp://ftp.videolan.org/pub/videolan/x264/snapshots/Configure after decompression

        ./configure--prefix=/root/codesourcery/sourcery_codebench_lite_for_xilinx_gnu_linux/arm-xilinx-linux-gnueabi/- -enable-shared

Modify the Config.mak file

# here instead of armarch=armsys=linux# here arm-xilinx-linux-gnueabi-gcccc=arm-xilinx-linux-gnueabi-gcc# remove-dhave_mmxext here- Dhave_sse2-darch_x86cflags=-wall-i.-o4-ffast-math-d__x264__-dhave_malloc_h-dsys_linux-dhave_pthread-s- Fomit-frame-pointer ldflags=-lm-lpthread-sas=nasm

ModifyMakefilefile

LIBX264.A:. Depend $ (OBJS) $ (objasm) Rm-linux-ar RC libx264.a $ (OBJS) $ (objasm) Arm-linux-ranlib libx264.a

Makemake Install

Then you can have the corresponding library generated under the/root/codesourcery/sourcery_codebench_lite_for_xilinx_gnu_linux/arm-xilinx-linux-gnueabi/lib.
4 cross-compiling XviDDownload xvid:http://downloads.xvid.org/downloads/xvidcore-1.1.3.tar.gz

        CD xvidcore-1.1.3/build/generic/

        ./configure--prefix=/root/codesourcery/sourcery_codebench_lite_for_xilinx_gnu_linux/arm-xilinx-linux-gnueabi/- -disable-assembly

    Gedit platform.inc  Modify CC=ARM-XILINX-LINUX-GNUEABI-GCC

5 cross-compiling ffmpeg download ffmpge:http://download.chinaunix.net/download.php?id=5532&resourceid=2990 tar xvjf ff mpeg-0.4.9-p20051120.tar.bz2
CD FFMPEG-0.4.9-P20051120/6 Cross compilation OpenCV
