Compiler error on android

[tpecholt]

Description

I am trying to build cpr for android so it's possible I am doing something wrong but:

I am getting an error in openssl.c. Code looks like:

num = X509_get_serialNumber(x);
if(num->type == V_ASN1_NEG_INTEGER)
  BIO_puts(mem, "-");

it looks like asn1_string_st is not properly defined so one can't access it through num->type. Perhaps some wrapper function should be used instead to query the type?

It's also possible there is more to #include on android to make this work like crypto/asn1.h.

Example/How to Reproduce

1. Create a cpr::Session
2. Set option ...
3. Perform the request
4. See error

Possible Fix

No response

Where did you get it from?
