maybe find a bug: error: 'class radosfs::Dir' has no member named 'nextEntry'

[lh2debug]

Hi,
I got the source code of radosfs in https://github.com/joaquimrocha/radosfs and installed it.
And I used build-ps/build-binary.sh to compile and install percona-server-rados.
But I got the following error.

/data/jameshli/percona-server-rados-radosfs_backtooldversion/percona-server-rados_withradosfs/storage/innobase/os/os0file.cc: In function 'int os_file_readdir_next_file(const char*, os_file_dir_t, os_file_stat_t*)':
/data/jameshli/percona-server-rados-radosfs_backtooldversion/percona-server-rados_withradosfs/storage/innobase/os/os0file.cc:3666:16: error: 'class radosfs::Dir' has no member named 'nextEntry'
     ret = dir->nextEntry(entry);
                ^
make[2]: *** [storage/innobase/CMakeFiles/innobase.dir/os/os0file.cc.o] Error 1

Then I checked the source code of radosfs. class radosfs::Dir actually has no member named 'nextEntry'.

Need help, Thanks!
