问题描述
今天编译了从github
下载的opencv-master
.随着网页http://ariandy1.wordpress.com/2013/02/13/raspberry-pi-rasbian-opencv/
中的这些说明,最后编译了OpenCV
成功地.但是当我写了一个简单的 C++
程序时,将它与 -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_video
链接,在终端中运行它.Illegal instructions
说发生了错误.但是当我把OpenCV
依赖的代码去掉,重新编译后,就可以成功运行了.我怀疑 apt-get
安装的包有一些错误.但我找不到他们.有人面临这个问题吗?
Today, I compiled the opencv-master
downloaded from github
. With these instructions in the webpage http://ariandy1.wordpress.com/2013/02/13/raspberry-pi-rasbian-opencv/
, and finally the OpenCV
compiled successfully. But when I wrote a simple C++
program, link it with the -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_video
, run it in terminal. An error occured, says Illegal instruction
. But when I remove the OpenCV
-dependent code, and recompile, it can run successfully.I doubt that the packages installed by apt-get
have some bugs. But I can't find them.Does anyone face this problem?
/etc/apt/sources.list
是:
deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
deb http://www.deb-multimedia.org/ wheezy main non-free
deb http://archive.raspbian.org/raspbian wheezy main contrib non-free
deb-src http://archive.raspbian.org/raspbian wheezy main contrib non-free

推荐答案
我不知道 Raspberry Pi 中的非法指令
的确切原因,但我找到了解决方案.只需使用 -DWITH_FFMPEG:BOOL='0'
重新编译 OpenCV
.如果没有 ffmpeg
,摄像机仍然可以工作.
I don't know the exact reasons of the Illegal instruction in Raspberry Pi
, but I find a solution. Just recompile OpenCV
with -DWITH_FFMPEG:BOOL='0'
. Without the ffmpeg
, the video camera still works.
