我在尝试按照本教程https://visualgdb.com/tutorials/raspberry/opencv/build/使用 VisualGDB 交叉编译 OpenCV 时遇到了这个问题

tar -xf b624b995ec9c439cbc2e9e6ee940d3a2-v0.1.1f.zip从命令行输入时，我也会遇到同样的错误。

CMakeList 在哪里使用命令tar.exe？是否可以用不会出错的东西（如 7zip）替换它？还是可以通过更新 tar 来解决这个问题？

即使以管理员身份，我也无法tar.exe从 C:\windows\System32删除或替换

这个问题有解决方法吗？

网上查了一下，tar 甚至都不支持 zip 文件，为什么要解压一个 zip 文件呢？

谢谢

我将问题追溯到第cmake\opencvdownload.cmake236 行

execute_process(COMMAND "${CMAKE_COMMAND}" -E tar xzf "${CACHE_CANDIDATE}" WORKING_DIRECTORY "${DL_DESTINATION_DIR}" RESULT_VARIABLE res)

如果我运行相同的命令行，我会收到此错误：

opencv\.cache\ade>cmake -E tar xzf b624b995ec9c439cbc2e9e6ee940d3a2-v0.1.1f.zip
CMake Error: Problem with archive_write_finish_entry(): Can't restore time
CMake Error: Problem extracting tar: b624b995ec9c439cbc2e9e6ee940d3a2-v0.1.1f.zip

而如果我用 7zip 替换它，它工作正常 7z x b624b995ec9c439cbc2e9e6ee940d3a2-v0.1.1f.zip

但是，CMake 不允许我使用“Cmake -E ...”从命令行执行 7zip 命令

所以临时解决方案，直到他们在 OpenCV 或 Cmake 中解决这个问题

修改cmake\opencvdownload.cmake第 236 行上的文件更改

execute_process(COMMAND "${CMAKE_COMMAND}" -E tar xzf "${CACHE_CANDIDATE}"

至

execute_process(COMMAND 7z x "${CACHE_CANDIDATE}"
