The strndup function is used in src/libs/zbxdbupgrade/dbupgrade.c in DBpatch_2010101 function. It is GNU function, not standard, so can't compile server and link zabbix server with SunStudio CC and guess same for other compilers except gcc.

I fix it by the following code. but couldn't be a good choice.

#Fix strndup issue on dbuphgrade.c
STRNDUP_FUNC="//#if defined(SOLARIS)||defined(_APPLE) || defined(WIN32) || defined(_FORTEC)
#define min(a,b) (a>b?b:a)
char *strndup( const char *s, size_t n )

{ size_t nAvail; char *p; if ( !s ) return 0; nAvail = min( strlen(s) + 1, n + 1 ); p = malloc( nAvail ); memcpy( p, s, nAvail ); p[nAvail - 1] = '\0'; /* printf( \"[PAH][%s][%d] nAvail=%d p=(%s)\n\", __FILE__, __LINE__, nAvail, p ); */ return p; }

"

echo "$STRNDUP_FUNC" >> src/libs/zbxdbupgrade/dbupgrade.c

sed '/static void parse_db_monitor_item_params.*/ i\
char *strndup( const char *s, size_t n );\
