I tried compile in my Dell Laptop with Slackware Current Latest Version.

And this error happened after run make command:

/usr/bin/ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_md4it'

I expected the following

curl/libcurl version

[curl -V output]

Please provide us with a full sequence of what you do when you build. You presumably did something before make.

If you cannot build it. How can you provide the curl -V output?

This code should always fail MD4 build with gnutls and openssl enabled

#if defined(USE_GNUTLS)
#include <nettle/md4.h>
/* When OpenSSL or wolfSSL is available, we use their MD4 functions. */
#elif defined(USE_OPENSSL) && !defined(OPENSSL_NO_MD4)
#include <openssl/md4.h>
#endif

should?

I can build curl fine with both and it does not fail on this.

I can't :(
./configure --without-gnutls --with-openssl builds fine
./configure --with-gnutls --with-openssl fails with #10110 (comment)

I suggest that someone that can reproduce the problem works on a fix. I cannot reproduce.

May be you have openssl with OPENSSL_NO_MD4?

I see logic with my openssl 1.1.1:

#if defined(USE_GNUTLS)
true #include <nettle/md4.h>
#elif defined(USE_WOLFSSL) && !defined(WOLFSSL_NO_MD4)
skipped #include <wolfssl/openssl/md4.h>
#elif defined(USE_OPENSSL) && !defined(OPENSSL_NO_MD4)
skipped #include <openssl/md4.h>
... skipped too
#endif

nettle/md4.h included, openssl/md4.h not

#if defined(USE_WOLFSSL) && !defined(WOLFSSL_NO_MD4)
false
#elif defined(USE_OPENSSL) && !defined(OPENSSL_NO_MD4)
true
skipped  #elif defined(USE_GNUTLS)
...skipped
#endif /* CRYPTO LIBS */

void Curl_md4it(unsigned char *output, const unsigned char *input,
                const size_t len)
{
  MD4_CTX ctx;

  MD4_Init(&ctx);
  MD4_Update(&ctx, input, curlx_uztoui(len));
  MD4_Final(output, &ctx);
}

And MD4_CTX still unknown here because #elif defined(USE_GNUTLS) skipped.
