c++ - Opencv静态库无法在eclipse中链接（添加了-ldl！）
问题描述
我想在我的 c++ 程序中静态链接 opencv，这样用户就不必自己下载 opencv。
我已经尝试了互联网上的所有方法来尝试在我的 c++ 程序中使用 opencv 静态库，但它不起作用。
我已经使用 -DBUILD_SHARED_LIBS=OFF 编译了 opencv 静态库，以在 /usr/local/lib 中生成 opencv lib 文件。所有文件都有.a 扩展名。我将这些文件移动到我的程序中的一个文件夹中，并将其与 eclipse 链接到 ("${workspace_loc:/${ProjName}/opencv lib}")
我已经包含了 -ljpeg -lpng -ltiff -lzlib -lpthread -lrt -ldl -lz -lm
我放了 -static 标志
我试图链接 /usr/local/include/opencv 和 /usr/local/bin
错误消息显示了一堆代码，例如 ... sum.cpp:(.text._ZN2cv3sumERKNS_11_InputArrayE+0xb19): undefined reference to `ippicviSum_16s_C4R'
...
和
/home/vivian/cuda-workspace/AutoVideoAnalyze_v4/opencv lib/libdl.a(dlopen.o)：在函数dlopen':
(.text+0x5): undefined reference to__dlopen'/home/vivian/cuda-workspace/AutoVideoAnalyze_v4/opencv lib/libdl.a(dlclose.o)中：在函数dlclose':
(.text+0x1): undefined reference to__dlclose'/home/vivian/cuda-workspace/AutoVideoAnalyze_v4/opencv lib/libdl.a(dlsym.o) 中：在函数dlsym':
(.text+0x5): undefined reference to__dlsym'collect2：错误：ld 返回 1 退出状态 make：*** [AutoVideoAnalyze_v4] 错误 1
我在谷歌上尝试了许多组合和不同的方式，但没有任何效果。有没有人真的在他们的 c++ 程序上静态链接了 opencv？请问可以分享你的作品吗？
解决方案
最后静态链接opencv我eclipse！我使用了 Opencv Cuda、IPP、ffmpeg 和许多其他库，所以还有更多库要包含！

库搜索路径（-L）：/usr/include、/usr/lib/x86_64-linux-gnu、/usr/lib/x86_64-linux-gnu/hdf5/serial/、/usr/local/share/OpenCV/3rdparty /lib、/usr/local/cuda-9.2/lib64、/usr/local/lib
如果你想知道你需要包含什么库，你可以看下看起来像下面脚本的General配置（*在构建opencv时出现）并将脚本中的每个库都包含到你想要链接的程序中静态的opencv。
