描述问题

在本地创建了一个新的环境。安装完opencv4之后发现环境问题，将其卸载后(sudo make uninstall)，安装了opencv3版本（手动编译安装），在编译时出现链接错误如下（最后面）。但是xmake l find_packages opencv可以找到opencv，信息如下：

{ 
  { 
    links = { 
      "opencv_dnn",
      "opencv_highgui",
      "opencv_ml",
      "opencv_objdetect",
      "opencv_shape",
      "opencv_stitching",
      "opencv_superres",
      "opencv_videostab",
      "opencv_calib3d",
      "opencv_videoio",
      "opencv_imgcodecs",
      "opencv_features2d",
      "opencv_video",
      "opencv_photo",
      "opencv_imgproc",
      "opencv_flann",
      "opencv_viz",
      "opencv_core" 
    },
    linkdirs = { 
      "/usr/local/lib" 
    },
    version = "3.4.7",
    includedirs = { 
      "/usr/local/include/opencv",
      "/usr/local/include" 
    } 
  } 
}

当强制指定opencv版本之后add_requires("opencv 3.x")，报错如下：

不知道opencv版本时，报错如下：

期待的结果

希望能够正常编译。个人认为可能是远程仓库的锅。因为我在本地安装的是opencv4.4.0和opencv3.4.7的版本，不存在报错中的4.2版本的问题。

关于链接报错问题，感觉跟我原先在这个issue提到的问题很像。但是那个问题的解决结果是安装动态链接库解决了。而这次我的opencv安装的确实是动态链接的,ls /usr/local/lib输出结果如下

奇怪，不知道为啥，现在执行成功了又，可以正常编译了。就是打开了打开了vscode，然后第一次编译还是失败，当再次把add_requires("opencv 3.x")改成add_requires("opencv")并在debug模式下进行编译就成功了（使用的是插件）。不知道可能的原因在哪里。在此之前搞了好久都是无法编译。 image

waruqi commented 4 years ago

首先，你来回切add_requires版本的时候，记得 xmake f -c 带 -c 强制清下配置cache，触发重新检测依赖包，不然会使用缓存的结果

error: package(opencv): version conflict, '4.2.0' does not satisfy '3.x'!

这个通常是由于，其他依赖包里面可能也add_deps指定了3.x的opencv依赖，或者其他地方还有 add_requries opencv 的依赖，导致版本冲突了，你可以找找

这个错误，你看下输出里面的实际link命令，opencv的库没有link进去，可以按刚说的 强制 xmake f -c 清下cache触发重新检测试试

另外，既然你本地有装，不想用远程的包，你可以人为指定不远程下载 add_requires("opencv", {system = true}) 仅从系统探测使用

默认模式是先从系统探测（指定了4.x就会探测系统对应版本，不匹配也会忽略），如果探测不到就会自动从远程下载

主要是无法链接问题的解决方案我很奇怪。因为当时尝试了很多种方法。sudo ldconfig重启都试了都是不行。opencv也重装了几遍也是不可以，就是启动vscode之后使用插件尝试编译就成功了。不知道可能问题在哪里。现在link是正常的。按我当时贴的报错的话，应该是没链接上的。正常的链接信息如下：

可以看到最后面是链接了opencv的，但是在之前的报错中似乎是没有正常链接。

通常是配置缓存问题，所以你可以按我之前说的xmake f -c 强制忽略历史缓存，重新检测所有就好，
