I've did what you proposed, and the error was gone, but of course new one
occured. The ones I have now are for this part of the code:
void initialize (void)
{
struct o_id *op = oids;
/* Win32: init winsock */
SOCK_STARTUP;
/* initialize library */
init_snmp("asynchapp");
/* parse the oids */
while (op->Name) {
op->OidLen = sizeof(op->Oid)/sizeof(op->Oid[0]);
if (!read_objid(op->Name, op->Oid, &op->OidLen)) {
snmp_perror("read_objid");
exit(1);
}
op++;
}} when parsing the oid I get: g++ -I/usr/local/include -I/usr/include/mysql -g
-c Testincpp.cpp -o Testincpp.oTestincpp.cpp: In function `void
initialize()':Testincpp.cpp:74: error: invalid conversion from `int*' to
`size_t*'Testincpp.cpp:74: error: initializing argument 3 of `int
read_objid(const char*, oid*, size_t*)' And for:
void asynchronous(void)
{
struct session *hs;
struct host *hp;
/* startup all hosts */
for (hs = sessions, hp = hosts; hp->name; hs++, hp++) {
struct snmp_pdu *req;
struct snmp_session sess;
snmp_sess_init(&sess); /* initialize session */
sess.version = SNMP_VERSION_2c;
sess.peername = strdup(hp->name);
// unsigned char comm[50]= hp->community;
sess.community = strdup(hp->community);
sess.community_len = strlen(hp->community);
sess.callback = asynch_response; /* default callback */
sess.callback_magic = hs;
if (!(hs->sess = snmp_open(&sess))) {
snmp_perror("snmp_open");
continue;
}
hs->current_oid = oids;
req = snmp_pdu_create(SNMP_MSG_GET); /* send the first GET */
snmp_add_null_var(req, hs->current_oid->Oid, hs->current_oid->OidLen);
if (snmp_send(hs->sess, req))
active_hosts++;
else {
snmp_perror("snmp_send");
snmp_free_pdu(req);
}
}
/* loop while any active hosts */
while (active_hosts) {
int fds = 0, block = 1;
fd_set fdset;
struct timeval timeout;
FD_ZERO(&fdset);
snmp_select_info(&fds, &fdset, &timeout, &block);
fds = select(fds, &fdset, NULL, NULL, block ? NULL : &timeout);
if (fds < 0) {
perror("select failed");
exit(1);
}
if (fds)
snmp_read(&fdset);
else
snmp_timeout();
}
/* cleanup */
for (hp = hosts, hs = sessions; hp->name; hs++, hp++) {
if (hs->sess) snmp_close(hs->sess);
}} When giving the hp->community to the sess.community, I get: Testincpp.cpp:
In function `void asynchronous()':Testincpp.cpp:309: error: invalid conversion
from `char*' to `u_char*' How can I fix that? Thanks a lot for your help
