050DR3 compile
 

Anyone else having issues with compiling zone?

I get several errors from client_process.cpp as follows:

Download the latest CVS. THis was fixed yesterday

The problem is on line 4333 of client_process.cpp. The wrong code may have been pushed out to CVS. Can you verify that the following is found on line 4333:

If it's not found, replace the if() statement there with what you see here. We'll work on getting the fix into CVS.

As a side note, I don't believe it makese sense to instantiate an ItemInst on its own. That's why I made it abstract.

krich, trump - is this the same problem that was encountered yesterday?

I suppose that it would be possible that a "return on fail" item could be a book or bag. A bit more code would take care of that potentiality.

Thanks guys! Much appreciated.

I saw something that made me quite happy with where you guys are going now; it was just one line, but it said much more:

Source management = a good thing (tm)

As a side project for some of you up and coming developers, can you look into these..

This worries me, when you jam a -1 into a nonnegative type, you end up with really weird outcomes... 4012331212312..... I've mentioned it to Merth, but neither one of us has really had the time to look at it. I started to try and fix the casts, just havent been able to follow through.

Im guessing this is because the first binary bit in an unsigned is one to indicate a negative number, so when its cast to a positive,its intrepreted incorrectly and becomes something abnormally large..

1001 would be -1 in signed, 9 unsigned for instance...

client_process and parser.cpp both have a slew of these warnings, anyone want to take a stab at discovering what the outcome is ?

Usualy it's the local storage with the wrong signedness. Things like the guild id which use abnormaly large storage types, use 0xFF 0xFFFF, thier max value, eg -1. So instead of using 0xFFFF in the code using -1 means you don't have to come back and change it if it changes to say 8bit 0xFF, the 0xFFFF would overflow, or if it goes up in size to 32bit you wind up with 0x0000FFFF which isn't 0xFFFF and then the code is broken but doesn't overflow. So long as the checks are consistant and there aren't any "0" checks..
