Segmentation error (Most likely my script) - Hobod - 08.07.2011

Hi, i've spent this afternoon creating a dynamic housing system for my server.
All worked fine, i could create, edit, delete etc. This was on my windows machine.
I uploaded it to my vps which runs ubuntu 10.10 x86 and tried to run it, and i received the segmentation error.
So i just tried commenting out the line that calls the function that loads my houses.
Then the server loaded up fine.
I could save houses and all that, and they'd show up but without being able to load them on startup it's a bit useless.
Un-commented the line and it wouldn't start again.
This is the code that gets called at startup, can anyone see whats wrong with it?

stock SetHouseOwned(propid, toggle, owner)
{
    if(toggle == 1)
    {
        DestroyDynamicPickup(housepickups[propid]);
        DestroyDynamicMapIcon(houseicons[propid]);
        housepickups[propid] = CreateDynamicPickup(1272, 1, houses[propid][propx], houses[propid][propy], houses[propid][propz], -1, -1, -1, 200.0);
        houseicons[propid] = CreateDynamicMapIcon(houses[propid][propx], houses[propid][propy], houses[propid][propz], 32, 0, -1, -1, -1, 500.0);
        houses[propid][ownerid] = owner;
        houses[propid][owned] = 1;
    }
    else if(toggle == 0)
    {
        DestroyDynamicPickup(housepickups[propid]);
        DestroyDynamicMapIcon(houseicons[propid]);
        housepickups[propid] = CreateDynamicPickup(1273, 1, houses[propid][propx], houses[propid][propy], houses[propid][propz], -1, -1, -1, 200.0);
        houseicons[propid] = CreateDynamicMapIcon(houses[propid][propx], houses[propid][propy], houses[propid][propz], 31, 0, -1, -1, -1, 500.0);
        houses[propid][ownerid] = 0;
        houses[propid][owned] = 0;
    }
    return 1;
}

When i looked into the server log when i uncommented it, it loads the houses, prints those 3 lines then the server stops.

Move your mysql_free_result() function inside the mysql_num_rows() if statement. You're freeing query data that might not exist.

Re: Segmentation error (Most likely my script) - Hobod - 09.07.2011

Tried what you said, and it still threw it back at me.
Really wonder what it could be.

Re: Segmentation error (Most likely my script) - WooTFTW - 09.07.2011

You forgot to add the delimeter

pawn Код:

while(mysql_fetch_row_format(Str, "|"))

I dont know if this will fix it, but give it a try.

Re: Segmentation error (Most likely my script) - Hobod - 09.07.2011

Nope didn't like it :/

EDIT:
Just being commenting out different parts of it to see what was causing it, seems to be the whole while statement.
If i comment the while statement out it starts up.
Confused because this function is basically a copy of my faction checkpoints loader, which works fine, but with the table changed and the big list of variables in this one.

EDIT 2:
Looked into the functions for the mysql plugin im using, works now.
Changed the function that goes through the database.
Thanks for the help anyway ^^

Re: Segmentation error (Most likely my script) - Hobod - 15.07.2011

Got this error once again, on a part of code that can't even go wrong, and it's worked for several weeks before this.

pawn Код:

mysql_connect("localhost", "root", "database", "");

That bit of code makes the server actually start up, but because the user is passworded it can't connect resulting in my server being practically dead.
But if i put the users password in, which is probably about 10 characters long into it, i get the segmentation error.
So close to scrapping this completely and start over, but i don't really want to seeing as i've spent ages on this. My first gamemode as well.

Who knows a MySQL tutorial ?

Re: Segmentation error (Most likely my script) - Hobod - 15.07.2011

This isn't the place to be asking for one

I'm after help with a bloody segmentation error not a mysql tutorial.
