人已经麻了，一个opencvc++一直报错，fatal error: opencv2/core.hpp: No such file or directory

cfzd commented 1 year ago

@onAugust1 你有安装opencv吗？有执行

ln -s /usr/local/include/opencv4/opencv2 /usr/local/include/opencv2

这个命令吗？

onAugust1 commented 1 year ago

@cfzd 嗯嗯·，都安装上了，但是我是用的autodl的平台，opencv安装到了root文件夹，还有一个build文件夹也在root文件夹下面，这个会有影响吗。我先安装的opencvc++，按官网给的指令，然后运行的ln -s /usr/local/include/opencv4/opencv2 /usr/local/include/opencv2指令，然后报错说 ln: failed to create symbolic link '/usr/local/include/opencv2': File exists，我按网上教程把-s改为了-sf，然后运行这个指令正确后，再进入culan中运行make，结果就报错了 include/spline.hpp:6:10: fatal error: opencv2/opencv.hpp: No such file or directory，这个是也是按网上教程说是新版本全打包在opencv中了，结果还是报错，回复不太及时，很抱歉。

@onAugust1 你可以尝试一下Option2的安装方式：

cd evaluation/culane
mkdir build && cd build
cmake ..
make
mv culane_evaluator ../evaluate

你也直接进入到这个路径：cd /usr/local/include/opencv2 && ls看看opencv.hpp到底存不存在。

或者你可以删掉rm /usr/local/include/opencv2这个link，然后重新执行一下ln -s /usr/local/include/opencv4/opencv2 /usr/local/include/opencv2

你好请问是直接按构建核心模块安装的吗

onAugust1 commented 1 year ago

对的，就按给的步骤来，但是建议用本地的远程登录工具，不要用autodl给的那个，那个我暂时没找到进入根目录的方法。
