Hello,
I need some help with extending the VFS for my project. I need hardlink
support, so I added the following to repos/os/include/vfs/directory_service.h's
Directory_service struct:
virtual int hardlink(char const *path, char const *hardlink_path)
{
(void) path;
(void)hardlink_path;
Genode::error("not implemented!");
return 0;
}
I have the Lwext4 plugin
(https://codeberg.org/jws/genode-wundertuete/src/branch/import-lwext4_from_world-2024-04-19)
setup for my project so I then extended
repos/wundertuete/src/lib/vfs/lwext4/vfs.cc's Lwext4_vfs_file_system struct:
int hardlink(char const *path, char const *hardlink_path) override
{
return ext4_flink(path, hardlink_path);
}
The problem is that hardlink uses the default implementation in my main code:
squidutils->_vfs_env.root_dir().hardlink(p2.string(), p1.string()); // Prints
'not implemented'
>From what I have read online the issue is that squidutils->_vfs_env.root_dir()
>is of type Directory_service, whereas I need it to be Lwext4_vfs_file_system.
>However, Lwext4_vfs_file_system is declared in the vfs.cc file above as
>opposed to being declared in a header.
Is there a way to use Lwext4_vfs_file_system without copying the entire source
of Lwext4 into my project's source code? Or am I perhaps going in the wrong
direction with all of this?
Best,
Rumen
