yeah but the ERROR you have is about your project lacking a WinMain, Windows Main entry point

I dont know if i should post this here but anyway. Everytime i include RakNet with the SDK i get this error:

pawn Code:

If you look into amx.h you'll find this code:

Code:

  #include <stdint.h>
#else
  #if defined __LCC__ || defined __DMC__ || defined LINUX
    #if defined HAVE_INTTYPES_H

    #else
      #include <stdint.h>
    #endif
  #elif !defined __STDC_VERSION__ || __STDC_VERSION__ < 199901L
    /* The ISO C99 defines the int16_t and int_32t types. If the compiler got
     * here, these types are probably undefined.
     */
    #if defined __MACH__
      #include <ppc/types.h>
      typedef unsigned short int  uint16_t;
      typedef unsigned long int   uint32_t;
    #elif defined __FreeBSD__
      #include <inttypes.h>
    #else
      typedef short int           int16_t;
      typedef unsigned short int  uint16_t;
      #if defined SN_TARGET_PS2
        typedef int               int32_t;
        typedef unsigned int      uint32_t;
      #else
        typedef long int          int32_t;
        typedef unsigned long int uint32_t;
      #endif
      #if defined __WIN32__ || defined _WIN32 || defined WIN32
        typedef __int64	          int64_t;
        typedef unsigned __int64  uint64_t;
        #define HAVE_I64
      #elif defined __GNUC__
        typedef long long         int64_t;
        typedef unsigned long long uint64_t;
        #define HAVE_I64
      #endif
    #endif
  #endif
  #define HAVE_STDINT_H
#endif
which basically checks if your platform/compiler has fixed-size integer types ([u]intX_t).

Since you're using Visual Studio it thinks you don't have those, however, Visual C++ since VS 2010 provides stdint.h (probably because they started implementing C++11 in that version), so you can simply define HAVE_STDINT_H and the errors will go away.

Why are you using mysql plugin while c++ has its own mysql library?
Reply

So... any idea why im having this crash?

Looks like you are not providing all mysql_connect parameters. You also have to provide the optional ones.

When i declare the function:

namespace Hooks
{
    class MySQLHooks
    {
        public: static cell mysql_connect(char *host, char *user, char* db, char *pass);
//more functions
    };
    cell MySQLHooks::mysql_connect(char *host, char *user, char* db, char *pass)
    {
        return (cell)sampgdk_InvokeNative(sampgdk_FindNative("mysql_connect"), "ssss", host, user, db, pass);
    }
//more functions
};
And the part where i use the function:

pawn Код:
struct connectiondata
{
    char *host = "localhost";
    char *db = "tdm";
    char *password = "";
    char *user = "root";
    cell ConnectionHandle = 0;
};
connectiondata *ConnectionData;

PLUGIN_EXPORT bool PLUGIN_CALL OnGameModeInit()
{
    logprintf("Inited");
    ConnectionData->ConnectionHandle = Hooks::MySQLHooks::mysql_connect(ConnectionData->host, ConnectionData->user, ConnectionData->db, ConnectionData->password); //this is the line where the plugin crashes
    if (Hooks::MySQLHooks::mysql_ping(ConnectionData->ConnectionHandle))
    {
        logprintf("The MySQL system inited correctly: (HOST: %s | User: %s | DB: %s | Password: %s", ConnectionData->host, ConnectionData->user, ConnectionData->db, ConnectionData->password);
    }
    else
    {
        logprintf("I coudnt connect to the MySQL system.");
    }
    return true;
}
Because you are using a wrong format with sampgdk_InvokeNative.
String is not like other one cell length types. If you use a string you MUST mention the length of string in format string.
You can do this like "S[FIXED_LENGTH]" or "[S[*num_argument_that_contains_sizeof_string]".
So try to use "S[1024]S[1024]S[1024]S[1024]".

I provide them but it keeps crashing, after some debugging i figure out that it crashes when i call the function (not the one from the gdk)
pawn Код:
cell Hooks::MySQLHooks::mysql_connect(char *host, char *user, char* db, char *pass, int port)
    {
        sampgdk::logprintf("hi");
        AMX_NATIVE native = sampgdk_FindNative("mysql_connect");
        if (native != NULL)
        {
            sampgdk::logprintf("it exists");
        }
        else sampgdk::logprintf(" it doesnt");
        return (cell)sampgdk_InvokeNative(sampgdk_FindNative("mysql_connect"), "ssssi", host, user, db, pass, port);
    }
The hi message doesnt even appear.

Here's the syntax of mysql_connect in PAWN

pawn Код:
mysql_connect(host[], user[], database[], password[], port = 3306, bool:autoreconnect = true, pool_size = 2)
But you've only filled the 5 first parameters. There are 2 more that aren't filled.

Im using the plugin version R7 and in the include the parameters of mysql_connect are
pawn Код:
(const host[], const user[], const database[], const password[], port = 3306)
Anyway i used the debugger of VS and im getting a Violation Access error when im calling the hooked function

Do you really know C++ !?
pawn Код:
connectiondata *ConnectionData;
This isn't even initialized, so it's null!

Finally, was waiting for 4.2

Hello! Unfortunatelly I have CentOS server and want to compile your GDK from the box.
What I have done:
updated GCC to 4.7.6 with devtoolset-1.1
updated python to 2.7
installed cmake
First of all try to make project and success with it.
Next step I turned on the following options:
PHP код:
option(SAMPGDK_STATIC "Build static library instead" ON)
option(SAMPGDK_BUILD_PLUGINS "Build example plugins" ON)
option(SAMPGDK_BUILD_AMALGAMATION "Build amalgamation" ON
And tried to recompile again:

I have a problem when linking to the static library, getting the following runtime error when i connect.
Код:
[debug] Run time error 20: "Invalid index parameter (bad entry point)"
This happens as soon as a player connects to the server, not when the server is started.

I don't get this error when i link to the dynamic lib. I've double checked all the project settings, i'm linking to the correct lib, and SAMPGDK_STATIC is defined. Also using the amalgamation.

Note: The function main() exists in the blank mode i have loaded. So that's not what is causing it.

If you're using amalgamation, you don't need anything else than sampgdk.c, sampgdk.h, and the plugin SDK.
You just need to define before including sampgdk the following macro: SAMPGDK_AMALGAMATION
Then, you're free to use sampgdk without (using) including the sampgdk (shared) library

Here's an example of the plugin, using SAMPGDK Amalgamation
PHP код:
#define SAMPGDK_AMALGAMATION
#include <sampgdk.h>
PLUGIN_EXPORT bool PLUGIN_CALL Load(void **ppData) { return sampgdk::Load(ppData); }
PLUGIN_EXPORT unsigned int PLUGIN_CALL Supports() { return sampgdk::Supports() | SUPPORTS_PROCESS_TICK;}
PLUGIN_EXPORT void PLUGIN_CALL Unload() { sampgdk::Unload(); }
PLUGIN_EXPORT void PLUGIN_CALL ProcessTick() { sampgdk::ProcessTick(); } 
You don't need "main", "dllMain", etc. to make this dll works, since the moment you have the functions above declared & defined, as well the samphp.def included into the project, and configured correctly.
