Yes, construct the BIO_METHOD at run time using the functions here:

https://www.openssl.org/docs/man1.1.0/crypto/BIO_meth_new.html

[Salz, Rich via openssl-users]

Yes, you will have to create the BIO object at run-time and use the settor 
methods.

[openssl-users] compiling cups-1.4.3 w/ OpenSSL 1.10 && BIO_METHOD

[Matthias Apitz]

Hello,

Compiling cups-1.4.3 against OpenSSL 1.10 gives the following error:

...
Compiling http.c...
http.c:216: error: variable `http_bio_methods' has initializer but
incomplete type

the code in question is:

#if defined(HAVE_SSL) && defined(HAVE_LIBSSL)
/*
 * BIO methods for OpenSSL...
 */

static int  http_bio_write(BIO *h, const char *buf, int num);
static int  http_bio_read(BIO *h, char *buf, int size);
static int  http_bio_puts(BIO *h, const char *str);
static long http_bio_ctrl(BIO *h, int cmd, long arg1, void *arg2);
static int  http_bio_new(BIO *h);
static int  http_bio_free(BIO *data);

static BIO_METHOD   http_bio_methods =
{
  BIO_TYPE_SOCKET,
  "http",
  http_bio_write,
  http_bio_read,
  http_bio_puts,
  NULL, /* http_bio_gets, */
  http_bio_ctrl,
  http_bio_new,
  http_bio_free,
  NULL,
};

Can I fix this somehow within the cups' code?
Thanks

matthias
