I did this

Defined both CURL_DISABLE_CRYPTO_AUTH and USE_NTLM.

I expected the following

A successful compilation. Instead I got an error saying "serverdata" was undefined (because it was being "defined" out).

curl/libcurl version

7.54.0

operating system

Windows, Visual Studio 2017.

Solution:

In curl_sasl.c, around line 417-ish (in Curl_sasl_continue() ), move char *serverdata; outside of the the #if !defined(CURL_DISABLE_CRYPTO_AUTH) define.

Or, alternatively, replace this:

#if !defined(CURL_DISABLE_CRYPTO_AUTH)
  char *serverdata;
  char *chlg = NULL;
  size_t chlglen = 0;
#endif

With this:

#if !defined(CURL_DISABLE_CRYPTO_AUTH) || defined(USE_NTLM) || defined(USE_KERBEROS5)
  char *serverdata;
#endif

#if !defined(CURL_DISABLE_CRYPTO_AUTH)
  char *chlg = NULL;
  size_t chlglen = 0;
#endif
