Hello

I am trying to compile:

 #include <gnutls.h>
 #include <gcrypt.h>
 #include <errno.h>
 #include <pthread.h>
GCRY_THREAD_OPTION_PTHREAD_IMPL;

          int main()
          {
             /* The order matters.
              */
             gcry_control (GCRYCTL_SET_THREAD_CBS, &gcry_threads_pthread);
             gnutls_global_init();
          }
I have all the requirements to do this, curl built with gnutls, and all the
headers/libraries in place.
In fact I am using an exactly duplicated debian 5 64 bit environment where
this code will compile with gcc.

However gcc on Cent OS 5 64bit yields this:

[root_at_localhost code]# gcc -lpthread test.cpp -O -lgnutls -lssl -lcurl
-pthread
test.cpp: In function int gcry_pthread_mutex_init(void**):
test.cpp:5: error: malloc was not declared in this scope
test.cpp:5: error: free was not declared in this scope
test.cpp: In function int gcry_pthread_mutex_destroy(void**):
test.cpp:5: error: invalid conversion from void* to pthread_mutex_t*
test.cpp:5: error: initializing argument 1 of int
pthread_mutex_destroy(pthread_mutex_t*)
test.cpp:5: error: free was not declared in this scope
test.cpp: In function int gcry_pthread_mutex_lock(void**):
test.cpp:5: error: invalid conversion from void* to pthread_mutex_t*
test.cpp:5: error: initializing argument 1 of int
pthread_mutex_lock(pthread_mutex_t*)
test.cpp: In function int gcry_pthread_mutex_unlock(void**):
test.cpp:5: error: invalid conversion from void* to pthread_mutex_t*
test.cpp:5: error: initializing argument 1 of int
pthread_mutex_unlock(pthread_mutex_t*)
[root_at_localhost code]#

I would love to know why GCRY_THREAD_OPTION_PTHREAD_IMPL;
works just fine on debian but not centos.

Thank you very much,

John
