# dfs_v2和lwext4冲突问题
大家好，我在RTThread_v5.2.0版本 bsp/qemu-virt64-aarch64下参考smart教程，编译时打开了
RT_USING_SMART和PKG_USING_LWEXT4,并执行了 `pkgs --update` ，scons编译时遇到问题如下

```
问题目前看是在lwext4-latest/ports/dfs_ext.c下
```
rt_inline const char *get_fd_file(struct dfs_file *fd)
{
    const char *fn = NULL;

if (fd)
    {
#if (RTTHREAD_VERSION >= RT_VERSION_CHECK(5, 0, 0))
        fn = fd->vnode->fullpath;  #成员变量fullpath只在dfs_v1的dfs_vnode结构体中出现，dfs_v2下没有
#else
        fn = fd->path;
#endif
    }

return fn;
}
```
目前看是dfs_v2和lwext4不兼容导致，但是RT_USING_SMART下目前好像只能配置dfs_v2？
所以想问下大家这个问题应该如何解决？谢谢
