I assume you're using GCC 4.3. If so, there's some information about this on the GCC website (http://gcc.gnu.org/gcc-4.3/porting_to.html) that I found through this forum (http://forum.mymediasystem.org/viewtopic.php?t=1258) using this Google search (http://www.google.com/search?hl=en&q=%E2%80%98atoi%E2%80%99+was+not+declared+in+this+ scope):
C++ language issues
Header dependency cleanup
As detailed here (Header dependency streamlining) (http://gcc.gnu.org/onlinedocs/libstdc++/manual/api.html#api.rel_430), 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 (http://eqemulator.cvs.sourceforge.net/eqemulator/EQEmuCVS/Source/common/dbcore.cpp?view=markup):
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:
#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.
