Ubuntu 11.10 上的 OpenCV

2021-12-10 00:00:00 opencv ubuntu c c++

我刚刚将我的系统从 ubuntu 11.04 更新到 11.10，现在我无法再编译任何包含对 OpenCV 库的引用的 C 程序

I've just updated my system from ubuntu 11.04 to 11.10 and now I can't compile anymore any C program that contain references to OpenCV libraries

我已经尝试重新安装 OpenCV(我使用 2.1 版本)，但我遇到了这个错误:

I've already tried to reinstall OpenCV (I use the 2.1 version) but I'm stuck with this error:

/tmp/ccArHTZL.o: In function `main':
z.c:(.text+0x59): undefined reference to `cvLoadImage'
z.c:(.text+0xa0): undefined reference to `cvNamedWindow'
z.c:(.text+0xb1): undefined reference to `cvShowImage'
z.c:(.text+0xbb): undefined reference to `cvWaitKey'
z.c:(.text+0xc5): undefined reference to `cvDestroyWindow'
z.c:(.text+0xd1): undefined reference to `cvReleaseImage'
collect2: ld returned 1 exit status

为了安装 OpenCV，我一直遵循以下步骤:

In order to install OpenCV I've always followed this procedure:

$ sudo apt-get install libcv2.1 libcv-dev libcvaux2.1 libcvaux-dev libhighgui2.1
     libhighgui-dev opencv-doc python-opencv

$ export LD_LIBRARY_PATH=/home/opencv/lib
$ export PKG_CONFIG_PATH=/home/opencv/lib/pkgconfig

$ pkg-config --cflags opencv
     -I/usr/include/opencv

$ pkg-config --libs opencv
     -lcxcore -lcv -lhighgui -lcvaux -lml

$ g++ -I/usr/include/opencv -lcxcore -lhighgui -lm hello.c

有人可以帮我吗?

推荐答案

你为什么不使用 pkg-config 对你有利?

Why don't you use pkg-config to your favor?

g++ hello.c -o hello `pkg-config --cflags --libs opencv`
