交叉编译opencv，解决不了这个错误，请大家帮忙！

由 beckham009 » 2010-04-02 17:08

我使用的编译工具是arm-none-linux-gnueabi-g++
想用opencv写个程序，放到devkit8000（omap3530芯片）开发板上。

在configure指令用的是下面这些

代码: 全选

./configure --host=arm-none-linux-gnueabi --without-gtk --without-carbon  --without-quicktime --without-1394libs --without-ffmpeg --without-python
--without-swig --enable-static --disable-shared --disable-apps
CXX= arm-none-linux-gnueabi -g++
CPPFLAGS=-I/usr/include
--prefix=/opt/opencv-arm6

成功。
Make成功。
Makeinstall成功。

之后进行交叉编译我自己写的程序diejia2.cpp

代码: 全选

arm-none-linux-gnueabi-g++ diejia2.cpp -o diejia2 -I/opt/opencv-arm6/include/opencv -L/opt/opencv-arm6/lib
-lcv -lcvaux -lcxcore -lhighgui -lml

出错，信息如下

代码: 全选

好像是highgui交叉编译出问题。

把diejia2.cpp注释掉里面的

代码: 全选

//ima=cvloadimage（“1.bmp”）

代码之后，没错了。生成了可执行文件。
但是没有cvloadimage怎么读取图像？？肯定要有的。

在网上看到好多人说，交叉编译时gtk和highgui是会出问题的，我想只有两条路可以解决问题
1 想办法把highgui交叉编译通过，不知道大家有没有做成的，指教一下
2 不用highgui，有没有其他读图片的方法，初学望指教

你离成功不远了~~~highgui的确有问题~~所以自己写采集接口吧~~·
至于loadimage~~~我给你三种方法吧~~
1）iplImage = cvCreateImageHeader(cvSize(width,heigth),IPL_DEPTH_8U,1);-
cvSetData(iplImage,pGrayBuffer,width*1); //第3个参数是行字节数
cvReleaseImageheader(&iplImage);
free(pGrayBuffer); //pGrayBuffer是程序里用来放灰度数据的空间，由calloc分配


（2）iplImage = cvCreateImage(cvSize(width,heigth),IPL_DEPTH_8U,1);
iplImage->imageData=pGrayBuffer;
iplImage->imageDataOrigin=pGrayBuffer;
cvReleaseImageheader(&iplImage);
free(pGrayBuffer);


(3) iplImage = cvCreateImage(cvSize(width,heigth),IPL_DEPTH_8U,1);
memcpy(iplImage->imageData,pGrayBuffer,iplImage->imageSize);
cvReleaseImage(&iplImage);
free(pGrayBuffer);
