编译和运行的问题 about lighttrack-ncnn HOT 10 CLOSED

把详细的报错贴出来啊

from lighttrack-ncnn.

大佬，这个按照你README中的提示，没办法编译啊，提示找不到文件，还请大佬详细指教哈

你的CMakeLists需要自己配的喔，依赖ncnn和opencv的库

from lighttrack-ncnn.

啊？我不太清楚咋配诶，能否劳烦大佬帮我配一下呢？

先看下你的错误

from lighttrack-ncnn.

make: *** 没有指明目标并且找不到 makefile。 停止。

这个就是报错信息，我按照你的README中的指导进入到build文件夹后执行：make -j && make install就报了上面这个错误，就这一句话

cmake .. && make -j && make install

我漏了一个命令，已经改过来，按照上面的写

好的，感谢大佬，我去试试哈，如果有问题再打搅你哈，谢谢大佬了

需要本机安装FFmpeg这个库，你先百度下，把它安装上

from lighttrack-ncnn.

好的，大佬
