certificate

[Amir Reda]

dear all
i have just made a code to make a certificate request from a node and my
certificate authority reply with the certificate
the node has attributes as below
X509_REQ *x;
EVP_PKEY *prk;
EVP_PKEY *puk;
X509 m_myCert;
//RSA structure contain both private and public key
RSA *rsa_keyPair;
X509_NAME *name;
the function which made the certificate request is
X509_REQ*
AeroRoutingProtocol :: MakeSignedCertReq (int bits, int serial, int days)
{
X509_REQ_set_pubkey(x,puk);
name=X509_REQ_get_subject_name(x);
// it gives errors i don't knoe why????
//X509_NAME_add_entry_by_txt(name,"C",MBSTRING_ASC, "UK", -1, -1, 0);
//X509_NAME_add_entry_by_txt(name,"CN",MBSTRING_ASC, "OpenSSL Group",
-1, -1, 0);
X509_REQ_sign(x,puk,EVP_md5());
return x;
}
the certificate authority receive this request and reply by the certificate
the function that make certificate as below

X509*
CertificateAuthority :: CreateCertificate (X509 *issuer, X509_REQ *req,
RSA *key )
{
X509 *cert = NULL;
int rv;
X509_NAME *xn_req = NULL, *subject = NULL;
EVP_PKEY *pkey = NULL;

//create the certificate
X509 * x509;
x509 = X509_new();
X509_NAME *issuerSubject = X509_get_subject_name(issuer);
X509_set_issuer_name(cert, issuerSubject);
xn_req = X509_REQ_get_subject_name(req);
X509_set_subject_name(cert, subject);
pkey = X509_REQ_get_pubkey(req);
rv = X509_set_pubkey(cert, pkey);
X509_gmtime_adj(X509_get_notBefore(cert), 0);
X509_gmtime_adj(X509_get_notAfter(cert), 36400);
signCertificateWithKey(cert, key);
return cert;
}

when i compile i got this error
../src/aerorp/model/certificate-authority.cc: In member function ‘X509*
ns3::AeroRP::CertificateAuthority::CreateCertificate(X509*, X509_REQ*,
RSA*)’:
../src/aerorp/model/certificate-authority.cc:58:37: error:

thanks allot for help
