dbcore.cpp error

I'm trying to compile 1119 under debian linux, but i'm getting this error =(

[CODE]-o ../common/dbcore.o
../common/dbcore.cpp: In static member function

wierd cut and paste error on my part i guess >.>

../common/dbcore.cpp: In static member function ‘static bool DBcore::ReadDBINI(char*, char*, char*, char*, int32&, bool&, bool*)’:
../common/dbcore.cpp:112: error: ‘atoi’ was not declared in this scope
make[1]: *** [../common/dbcore.o] Error 1
make[1]: Leaving directory `/home/equsr/EQemu/source/EQEmu-0.7.0-1119/world'
make: *** [all] Error 2

Did you edit your source code before you started to compile? There are multiple changes that you have to make for it to compile. Though, I have never seen that particular error.

I assume you're using GCC 4.3. If so, there's some information about this on the GCC website that I found through this forum using this Google search:

C++ language issues
Header dependency cleanup

As detailed here (Header dependency streamlining), many of the standard C++ library include files have been edited to only include the smallest possible number of additional files. As such, many C++ programs that used std::memcpy without including <cstring>, or used std::auto_ptr without including <memory> will no longer compile.

Usually, this error is of the form:

error: 'strcmp' was not declared in this scope

The table below shows some of the missing items, and the header file that will have to be added as an #include for the compile to succeed.
If missing Then include this header
find, for_each, sort <algorithm>
ostream_iterator, istream_iterator <iterator>
auto_ptr <memory>
typeid <typeinfo>
isalnum, toupper <cctype>
INT_MIN, INT_MAX, RAND_MAX <climits>
printf <cstdio>
atoi, free, rand, exit <cstdlib>
EXIT_FAILURE <cstdlib>
strcmp, strdup, strcpy, memcpy <cstring>

In other words, change this in common/dbcore.cpp:

Code:

    1 #include "../common/debug.h"

    2 #include "../common/files.h"

    3 

    4 #ifdef WIN32

    5 #include <winsock2.h>

    6 #endif

    7 

    8 #include <iostream>

    9 using namespace std;

   10 #include <errmsg.h>

   11 #include <mysqld_error.h>

   12 #include <limits.h>

   13 #include "dbcore.h"

   14 #include <string.h>

   15 #include "../common/MiscFunctions.h"

   16 

   17 #ifdef WIN32

   18         #define snprintf        _snprintf

   19         #define strncasecmp        _strnicmp

   20         #define strcasecmp        _stricmp

   21         #include <process.h>

   22 #else

   23         #include "unix.h"

   24         #include <pthread.h>

   25 #endif

   26 

   27 #ifdef _EQDEBUG

   28         #define DEBUG_MYSQL_QUERIES 0

   29 #else

   30         #define DEBUG_MYSQL_QUERIES 0

   31 #endif

to something like this:

Code:

#include "../common/debug.h"

#include "../common/files.h"



#ifdef WIN32

#include <winsock2.h>

#endif



#include <iostream>

using namespace std;

#include <errmsg.h>

#include <mysqld_error.h>

#include <limits.h>

#include "dbcore.h"

#include <string.h>

#include "../common/MiscFunctions.h"

#include <cstdlib>



#ifdef WIN32

        #define snprintf        _snprintf

        #define strncasecmp        _strnicmp

        #define strcasecmp        _stricmp

        #include <process.h>

#else

        #include "unix.h"

        #include <pthread.h>

#endif



#ifdef _EQDEBUG

        #define DEBUG_MYSQL_QUERIES 0

#else

        #define DEBUG_MYSQL_QUERIES 0

#endif

Or you could do it the lazy way and just downgrade to 4.2 or 4.1 of GCC. I personally have 4.1 and it compiles fine. Long term, this is probably something that may needed to be added to the source in general.

Well, the wiki should be pretty up-to-date for getting everything to compile correctly without having to change anything that isn't in the wiki. I know people have done it as recently as this week and it worked fine. Unless there was some change since then that would cause this, I imagine you missed something in there.

yea acually i'm using gcc 4.2 i'll try this here in a few. Guess i shoulda installed etch instead of lenny >.>

after applying your fix to about a dozen files Oo, now i'm getting this error.

client.h:141: warning: ‘typedef’ was ignored in this declaration
zone.cpp: In member function ‘bool Zone::LoadZoneObjects()’:
zone.cpp:184: warning: missing braces around initializer for ‘uint32 [2]’
make[1]: *** [zone.o] Error 1
make[1]: Leaving directory `/home/jenco/EQemu/source/EQEmu-0.7.0-1119/zone'
make: *** [all] Error 2

i got around that error by passing a fpermissive flag to zone's makefile (i know i should'nt do that to make things compile =( ) but it just looks like eqemu just need to be updated to gcc's new specs is all.
