warning: data definition has no type or storage class

[omronz]

Hi everyone

I am doing a simple SSL server program using OpenSSL. I just initialize the OpenSSL library and i compile. Then the GCC return a warning message "data definition has no type or storage class. The snippet is as below :-

#include <stdio.h>
#include <openssl/bio.h>
#include <openssl/ssl.h>
#include <openssl/err.h>

OpenSSL_add_all_algorithms(); //This is where the warning message returned
SSL_load_error_strings(); //This is where the warning message returned

int main()
{
   return 0;
}

Hope that anyone of you can help me. My OpenSSL version is 0.9.8g 19 Oct 2007.

Thanks

You can pre-declare your functions, but you can't call them outside of function.

I hope that's just a cut-n-paste mistake and you see your problem, otherwise I think you need to start with a "hello world" and a couple of programming books. Programming isn't something you can just copy-n-paste from sources on the web.

I try to use ANSI C hash-table implementation and also get the same warning (and 1 error and 1 note). The following snippet is from YACC declarations part:

 #include "strmap.h" // ANSI C hash-table implementation (definitions are in "strmap.c")
// ...
StrMap *SYMTAB;
SYMTAB = sm_new(10);
// ... 
  

Besides the warning (in the thread title), I also get

asm.y:(2nd line): error: conflicting types for ‘SYMTAB’
asm.y:(1st line): note: previous declaration of ‘SYMTAB’ was here

What am I doing wrong?
