openssh unix dev - Feb 2010 - ld: Unsatisfied symbol "options" in file ./libssh.a[hostfile.o]

Hi All,
I have want to add a option in ssh_config to co-work with ldap.But when I am
compiling , i was encountered a
ld error, which says "cc -o ssh-keygen ssh-keygen.o -Wl,+nodefaultrpath -L.
-Lopenbsd-compat/ -lssh -lopenbsd-compat  -lz -lnsl -lxnet -lsec -lgssapi_krb5
-lkrb5 -lpthread
ld: Unsatisfied symbol "options" in file ./libssh.a[hostfile.o]
1 errors."
The following is my codes:
I have externed Options options like " extern Options options" in
hostfile.c
 
..........
extern Options options
..........
static HostStatus
check_host_in_hostfile_by_key_or_type(const char *filename,
    const char *host, const Key *key, int keytype, Key *found, int *numret)
{
        FILE *f;
        char line[8192];
        int linenum = 0;
        u_int kbits;
        char *cp, *cp2, *hashed_host;
        HostStatus end_return;
        debug3("check_host_in_hostfile: filename %s", filename);
        /* Open the file containing the list of known hosts. */
        f = fopen(filename, "r");
        if (!f)
        {
                if(options.usesshldaphostkey)
                        return check_hostkey_in_ldap(host,key,HOST_NEW);
                else

                return HOST_NEW;
}
.......
 
So any ideas about this?
Thanks!

ssh-keygen doesn't have a config file, so it doesn't link against
anything that provides an options struct. You need to pass your new
flag in as an argument.

Hi Miller,
 
Oh, thank you very much. I shoud pass the option "usesshldaphostkey"
as a
argument to the function "check_host_in_hostfile_by_key_or_type".
 
Best regards,
Kai Yang
