working on a small homework which requires convert pvk private key to PKCS#8

OpenSSL 1.0.2.</span></font></div></span></div><span>

<div style="margin:0;"><font size="2" face="Calibri,sans-serif"><span style="font-size:11pt;">I
can get pvk private key components (Public exponent, modulus, prime1,
prime2, exponent1, exponent2, coefficient, private exponent) properly,
and convert to a valid
RSA format (<font face="Courier New">RSA_check_key()returns success</font>).</span></font></div>
<div style="margin:0;"><font size="2" face="Calibri,sans-serif"><span style="font-size:11pt;"> </span></font></div>
<div style="margin:0;"><font size="2" face="Calibri,sans-serif"><span style="font-size:11pt;">Now
I need to convert the key in RSA format to EVP_PKEY, then to PKCS#8. I
have tried the following functions, all of these functions return 0
(failure) without any
further debugging information/clues:</span></font></div>
