Question

我正在尝试使用自己的库打包opencv库。我是这样做的：

   ar x libopencv_highgui.a
   ar x libopencv_core.a
   ar x libopencv_imgproc.a
   ar x libmyown.a
   ar cru libnew.a *.o

当我使用这个新库libnew.a时，会出现很多这样的错误：

Answer 1

opencv_imgproc和opencv_highgui模块具有相同名称的源文件（例如，util.cpp）。来自util.o的目标文件opencv_highgui将被opencv_imgproc中具有相同名称的目标文件覆盖。这就是你遇到链接错误的原因。

尝试使用AR工具的MRI脚本模式。使用以下内容创建MRI脚本文件（例如，script.mri）：

create libnew.a
addlib libopencv_core.a
addlib libopencv_imgproc.a
addlib libopencv_highgui.a
addlib libmyown.a
save
end

并将其与ar工具一起使用：

ar -M <script.mri

使用我自己的库打包opencv库
