Hi everyone,
    
    Now i am studying using libcurl ro implement FTP/SFTP transfer, but there are two problems:

    (1) I installedf curl-7.19.4 and found some examples like "ftpget.c" and "ftpupload.c", both of them work well; but I want to know How i could implement FTP manipulation like "delete_file", "delete_dir", "dir_remote" and "create_dir"? I checked the Token "CURLOPT", but did not find any clue.

    (2) I know that Libcurl needs libssh2 to support SFTP, so I downloaded libssh2-1.1 and openssl-0.9.8k(dependency of libssh2-1.1)£¬but installation failed due to a compiling error like below:
     
gcc -shared -Wl,-M -Wl,.libs/libssh2.so.1.0.1.exp -Wl,-h -Wl,libssh2.so.1 -o .libs/libssh2.so.1.0.1 .libs/channel.o .libs/comp.o .libs/crypt.o .libs/hostkey.o .libs/kex.o .libs/mac.o .libs/misc.o .libs/packet.o .libs/publickey.o .libs/scp.o .libs/session.o .libs/sftp.o .libs/userauth.o .libs/transport.o .libs/version.o .libs/openssl.o -L/home/xiaolech/Open_SSL/lib -lssl -lcrypto -lz -lnsl -lsocket -lc

...
ld: fatal: relocations remain against allocatable but non-writable sections
    
  I am not very clear about how to resolve it, any body knows?

    Thanks a lot!
