作为我正在开展的更大项目的一部分，我需要在C程序上使用OpenCV库。我在Fedora 17 32位中使用yum安装了OpenCV和opencv-devel。我指示预处理器导入opencv / cv.h和opencv / highgui.h作为必要的头文件。
正如我所提到的，gcc用于编译整个C项目。但是，链接器似乎存在问题。
每当我尝试编译项目（gcc opencv.c -o opencv）时，我都会得到一个错误列表，类似于：
/tmp/ccLJWE0c.o: In function `cvRound': opencv.c:(.text+0x19):

另外，当我使用：
编译程序时gcc opencv.c -o opencv `pkg-config --libs --cflags opencv` -ldl
我仍然得到：
/usr/bin/ld: /tmp/ccMRviO3.o: undefined reference to symbol 'lrint@@GLIBC_2.1'
/usr/bin/ld: note: 'lrint@@GLIBC_2.1' is defined in DSO /lib/libm.so.6 so try adding it to the linker command line
/lib/libm.so.6: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
我一直在努力寻找解决方案，但似乎没有解决问题的方法。在OpenCV文档中，他们提到了安装所需库的不同方式，但我并不完全理解我必须遵循的步骤。我认为Fedora devel Packages在编译和准备使用的地方。无论如何，如果这是问题，是否有一种简单的方法可以使整个过程发挥作用？
我已经在Visual Basic中编写了6年的编码，但我刚刚开始学习C作为我大学教育的一部分;因此我在操纵GCC方面不是很有经验。 :(我会请你尽可能地解释！:)
任何帮助表示赞赏！提前致谢！！！ ：d
