I'm trying to write a very basic app to test how pawn with c++ works, tough I'm having some issues.
Since amxx mod x is based of pawn I taught that someone could help me.
Heres my c++ app code:
Code:
#include <stdio.h>
#include <string.h>
#include "amx/amx.h"
#include "amx/amxaux.h"

void print_int(int stuff)
{
    printf("%i\n",stuff);
}

static cell AMX_NATIVE_CALL n_print_int(AMX *amx, const cell *params)
{
    print_int( (int)params[1] );
}

extern "C"
int amx_PrintInit(AMX *amx)
{
    static AMX_NATIVE_INFO print_Natives[] =
    {
        { "print_int", n_print_int },
        { 0, 0 }
        /* terminator */
    };
    return amx_Register(amx, print_Natives, -1);
}

int amx_PrintCleanup(AMX *amx)
{
    return AMX_ERR_NONE;
}


void ErrorExit(AMX *amx, int errorcode)
{
    printf("Run time error %d: \"%s\"\n",
           errorcode, aux_StrError(errorcode));
    exit(1);
}
void PrintUsage(char *program)
{
    printf("Usage: %s <filename>\n", program);
    exit(1);
}


int main(int argc,char *argv[])
{
    size_t memsize;
    void *program;
    AMX amx;
    cell ret = 0;
    int err;
    cell index;
    memsize = aux_ProgramSize("1st.amx");
    program = malloc(memsize);


    if (program == NULL)
        ErrorExit(&amx, err);
    err = aux_LoadProgram(&amx, "1st.amx", program);
    if (err)
        ErrorExit(&amx, err);

    err=amx_PrintInit(&amx);
    if (err == AMX_ERR_NONE)
        printf("SUCCESS?\n");
    else
        ErrorExit(&amx, err);



    err = amx_FindNative(&amx, "print_int", &index);
    if (err == AMX_ERR_NONE)
        printf("SUCCESS?\n");
    else
        ErrorExit(&amx, err);


    err = amx_Exec(&amx, &ret, AMX_EXEC_MAIN);
    if (err)
        ErrorExit(&amx, err);

    if (ret != 0)
        printf("%s returns %ld\n", "1st.amx", (long)ret);

    amx_PrintCleanup(&amx);

    amx_Cleanup(&amx);
    free(program);
    printf("BYE!!!!\n");
    //VirtualFree(program, 0, MEM_RELEASE);
    return 0;
}
heres p code(1st.p):
Code:
#include "test.inc"
public foo()
{
return 1
}
main()
{
//print_int(1)
return 100
}
heres test.inc:
Code:
native print_int(value)
I compile the p code with the pawn compiler which I got with the library and everything compiles correctly and the 1st.amx is produced.
I put my 1st.amx into my apps folder.
Launch the app.
It fails at finding native func print_int.

what am I doing wrong?
