Missing Content "Cross Compiling Opencv2.2 for I.MX53 QSB"

YiayitKarabulut — Wed, 22 Feb 2012 22:43:15 GMT

Dear All,

I am searching "Cross Compiling Opencv2.2 for I.MXQSB2.2" content but i cant find it. It was written by eric gregori and was mentioned in FTF11_CON_F0321.pdf . Is there anyway how i can find it?

Many Thanks in advance,

Yigit Karabulut

I found this which maybe of help. I do not have the VMware image, but the steps are there for building Opencv2.2.

1) Unzip i.MX53QSB VMWare image into directory
------------------------------------------------
folder: vm_Ubuntu
user: lucid
passwords: lucid
L2.6.35_11.01.00_ER_source.tar.gz

2) Open a terminal window

3) Build LTIB for i.MX53 QSB
------------------------------
$ cd /home/lucid/ltib
$ ./ltib -c

Selection (imx5x)
board (mx53_loco)

4) Get OpenCV 2.2
-----------------
$ cd ~
$ mkdir OpenCV22_CrossBuild
$ cd OpenCV22_CrossBuild
$ wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.2/OpenCV-2.2.0.tar.bz2
$ tar -xjf ./OpenCV-2.2.0.tar.bz2
$ cd ./OpenCV-2.2.0/

5) Apply patches
-----------------
$ wget http://imxcommunity.org/group/computervisionusingtheimx/forum/attachment/download?id=4103961%3AUploadedFile%3A17039
$ wget http://imxcommunity.org/group/computervisionusingtheimx/forum/attachment/download?id=4103961%3AUploadedFile%3A17401
$ wget FileNotFound**LlzQ2YNNNtsb5tdZq/emgOPenCV22gbtFix.patch
$ patch -p1 < opencv2.2armxmsiftissue.patch
$ patch -p0 < emgOPenCV22gbtFix.patch

6) Build OpenCV
----------------
$ mkdir release
$ cd release
$ pwd
/home/lucid/OpenCV22_CrossBuild/OpenCV-2.2.0/release

$ export PATH=/opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin:$PATH
$ sudo apt-get install cmake
$ cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/home/lucid/ltib/rootfs/usr/ -DCMAKE_TOOLCHAIN_FILE:PATH=${PWD}/../imx53.cmake -DCMAKE_FIND_ROOT_PATH=/home/lucid/ltib/rootfs/ -DWITH_FFMPEG=OFF -DWITH_GSTREAMER=OFF -DWITH_PYTHON=OFF -DWITH_GTK=OFF -DBUILD_EXAMPLES=ON ..
$ make
$ sudo make install

The above cmake parameters will build a version of
highgui without window support. To see your video
you will need a fb interface. This was done to avoid
the overhead of having GTK and X11 on the system.

7) Build applications
-----------------------
$ cd ~/ltib/rpm/BUILD
GET LABS

$ cd /home/lucid/ltib
$ ./ltib -m shell
LTIB> cd /home/lucid/ltib/rpm/BUILD/Labs

8) Setting up NFS on the i.MX53QSB
------------------------------------
Requires a serial port @ 115200,8,n,1

Open hyperterminal

setenv serverip 192.168.1.23
setenv bootfile uImage
setenv nfsroot 192.168.1.23:/home/lucid/ltib/rootfs
setenv bootargs_base 'setenv bootargs console=ttymxc0,115200'
setenv bootargs_nfs 'setenv bootargs ${bootargs} root=/dev/nfs ip=dhcp nfsroot=${nfsroot},v3,tcp video=mxcdi1fb:BGR24,XGA di1_primary tve '
setenv bootcmd_net 'run bootargs_base bootargs_nfs;bootm'
setenv bootcmd 'dhcp; run bootcmd_net'
saveenv

I also edited /etc/exports
To configure nfs server, add lines to /etc/exports like this (below example exports /home and everything under it.
/home *(rw,no_root_squash)
Then restart the nfs server:
sudo /etc/init.d/nfs-kernel-server restart

class
1) ltib -c
2) flash bootloader to SD
3) configure uboot for NFS
4) build and run labs

echo -n 0 > /sys/class/graphics/fb0/blank

thanks for help, i notice that patch files are missing :( . where can i possibly find them?

Hi,

I have not tried going through the build steps, sorry about the missing patches. I found a zip file which I have attached that has more information and some patches. Hopefully this will fill in the missing holes as I have no other areas to search. Good luck.

Can you describe how to use these file,please.I have been follow this but it doesn't work.Thank you so much.:D.

FranciscoCarril — Mon, 26 Nov 2012 20:25:14 GMT

Follow the Guide posted by Curtis and the patches as well, then it will probably fail close at 58% due to some code error:

Building CXX object modules/ml/CMakeFiles/opencv_ml.dir/src/gbt.o

/home/windows/Downloads/OpenCV-2.2.0/modules/ml/src/gbt.cpp: In member function 'virtual void CvGBTrees::find_gradient(int)':

/home/windows/Downloads/OpenCV-2.2.0/modules/ml/src/gbt.cpp:474: error: 'expl' was not declared in this scope

make[2]: *** [modules/ml/CMakeFiles/opencv_ml.dir/src/gbt.o] Error 1

make[1]: *** [modules/ml/CMakeFiles/opencv_ml.dir/all] Error 2

make: *** [all] Error 2

windows@ubuntu:~/Downloads/OpenCV-2.2.0$

This can be fixed with the following modification:

> Change line 14 ofOpenCV-2.2.0/modules/ml/src/gbt.cppfrom "Android" to "1"

- before -

#if Android
#define expl(x) exp(x)
#endif

- after -

#if 1
#define expl(x) exp(x)
#endif

With this Change it should work for 100%

Good luck!!

Hi Francisco,can you attach patch 1. I found a file name's "opencv-2.2-arm-imx53-sift-issue.patch" in 314-opencv_22_ltib.zip about.Is this patch1??, which is use to build a version of highgui without window support.:D.

Re: Missing Content "Cross Compiling Opencv2.2 for I.MX53 QSB"

FranciscoCarril — Mon, 03 Dec 2012 14:34:35 GMT

Yes, inside the zip file you have patch #1 the other patch is the one i sent you in the other post.

Re: Missing Content "Cross Compiling Opencv2.2 for I.MX53 QSB"

hoanganhngo — Tue, 04 Dec 2012 02:14:07 GMT

This is step by step what i've done:

$ cd ~

$ mkdir OpenCV22_CrossBuild

$ cd OpenCV22_CrossBuild

$ wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.2/OpenCV-2.2.0.tar.bz2

$ tar -xjf ./OpenCV-2.2.0.tar.bz2

$ cd ./OpenCV-2.2.0/

copy opencv-2.2-arm-imx53-sift-issue.patch from zip file to /home/lucid/314-opencv22_ltib

$ patch -p1<opencv-2.2-arm-imx53-sift-issue.patch (this patch is from zip file above).

$ patch -p2< gbt.patch

copy imx53.cmake from zip file to /home/lucid/OpenCV22_CrossBuild/OpenCV-2.2.0

$ mkdir release
$ cd release
$ pwd

$ export PATH=/opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin:$PATH
$ sudo apt-get install cmake

cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/home/lucid/ltib/rootfs/usr/ -DCMAKE_TOOLCHAIN_FILE:PATH=${PWD}/../imx53.cmake -DCMAKE_FIND_ROOT_PATH=/home/lucid/ltib/rootfs/ -DWITH_FFMPEG=OFF -DWITH_GSTREAMER=OFF -DWITH_PYTHON=OFF -DWITH_GTK=OFF -DBUILD_EXAMPLES=ON ..

$ make

........

and it stop at 57% because of this error:

home/lucid/OpenCV22_CrossBuild/OpenCV-2.2.0/modules/highgui/src/cap_dc1394_v2.cpp:49:27: error: dc1394/dc1394.h: No such file or directory

/home/lucid/OpenCV22_CrossBuild/OpenCV-2.2.0/modules/highgui/src/cap_dc1394_v2.cpp:53: error: 'dc1394error_t' does not name a type.

Can you tell me what is the mistake in these step. I try to solve this for a month but I have no result.:((.

Hi Francisco,

I am also trying to build the OpenCV2.2 for i.MX53 QSB Platform.

I was able to successfully build till 75%, then i am getting the errors as mentioned below.

I have followed the instructions provided by as mentioned in the above post.

Any idea what I might be missing here??
