frustrating crash bug

[will_asher]

I might actually take you up on that. Could you really send me a working build environment? I tried downloading and installing Visial C++, but for some reason the one I downloaded wasn't able to install correctly on my computer.

I might actually take you up on that. Could you really send me a working build environment? I tried downloading and installing Visial C++, but for some reason the one I downloaded wasn't able to install correctly on my computer.

Was this the one you tried to install? How did the install go wrong, any error messages?

I think Pete was talking about the instructions for using the VC++ IDE I gave, so if you can't get VC++ to work they aren't much use. You'll also have to fix a lot of compile errors even if you do get it to work.

When I try putting a bunch of plogs, it seems to crash in a different place each time.
I tried downloading gdb, but I can't figure out how to use it. There's no executible and the readme file says to type 'configure' then 'make' neither of which do anything. (Is there maybe a debugger that's easier to use?)

If you're on Linux, try installing ddd - it's a handy front-end for gdb which makes debugging a lot easier. (I can't be more specific until I know your distro.)

Was this the one you tried to install? How did the install go wrong, any error messages?

I got it from a different website, but it looked like the same thing. It started downloading and seemed like it was going extremely slow. Then it stopped and gave me an error message saying something like "This ____ component was not able to install."
I'll try downloading it from the site you linked to and try again.

(BTW, I'm on Windows XP and I have no idea what mingw or msys are.)

Update: I finally got Visual C++ up and running (Thanks Paul), now to find the bug..

[will_asher]

I tell it to 'build solution' and it gives me an error saying:

Command line error D8045 : cannot compile C file '..\..\win\readdib.c' with the /clr option

I couldn't find anything about this in the visual C++ help.

[PaulBlay]

Command line error D8045 : cannot compile C file '..\..\win\readdib.c' with the /clr option

I couldn't find anything about this in the visual C++ help.

Right. Well the first thing is to check what is present in your 'command line'. As it's talking about compiling then it should be the one in ....

Project -> Properties -> C/C++ -> Command line.

Mine looks like

/Od /I "C:\RL\Angband311\src" /D "_MBCS" /Gm /EHsc /RTC1 /MDd /Fo"Debug\\" /Fd"Debug\vc90.pdb" /W4 /nologo /c /ZI /TC /errorReport:prompt

with

/DWINDOWS

in the separate text box below. As you can see there is no /clr in there. If you do have /clr in your command line then you should probably see where it was set in the properties.

[PaulBlay]

I tell it to 'build solution' and it gives me an error saying:

Command line error D8045 : cannot compile C file '..\..\win\readdib.c' with the /clr option

Found it. In

Project -> Properties -> Configuration properties -> General

Common Language Runtime support should be set to "No Common Language Runtime support"

I don't know why yours was set, unless you started from a "CLR empty project" instead of a "General empty project".

[will_asher]

I found where it has '/clr' in the command line, but I can't find how to get rid of it.
EDIT: nevermind you just told me as I was writing this message. thanks

EDIT: do I really have to fix all these 1223 so-called errors where there's really nothing wrong with the code in order to debug it?
(EDIT: 1202 errors)
(EDIT: 1155 errors ..maybe this isn't so bad)
(EDIT: ..then again maybe it is. I fixed several things it pointed out and it still says 1155.)
(EDIT: 1063 errors)
(EDIT: 1012 errors)
(EDIT: 867 errors)
(EDIT: 623 errors)
(EDIT: 458 errors)
(EDIT: 201 errors)

[PaulBlay]

EDIT: do I really have to fix all these 1223 so-called errors where there's really nothing wrong with the code in order to debug it?

I only had 605 when I compiled it (the latest version released).

And yes, if you want to debug in in VC++ you have to follow the standards VC++ compiles to. Which means either getting rid of the 605 (or whatever) errors when compiling as C, or getting rid of the 190 errors when compiling as C++.

Most of the former are probably things like

void foo(void)
{
  int a;
  a = 1 + 3;
  [i]int b = 2;[/i]
}

The line in italic is in error according to C89, because you are declaring a variable some place other than the start of a block.

There are probably fewer errors from a C++ perspective, but (from experience) they are quite likely to be more fiddly to fix.

[will_asher]

Well I got rid of all those 1223 errors and they were all because of variables not being declared at the beginning of the block.

Then it said there was another 70 errors of another kind. Now it says:
unresolved external symbol _____ referenced in function ______

I think all 70 of these additional errors are this type. I looked on the internet for a soluton to this error and I found something which said to disable the "treat wchar_t as built-in type" option in C/C++ -> Language. So I did that and it didn't help, it's still giving me the same errors.

I only had 605 when I compiled it (the latest version released).

I've done a lot since 1.0.97. For instance, I created (and fixed) another 618 compile errors.

[Pete Mack]

You are done with compiling. Welcome to DLL hell. Without a list of some of the external symbols, it's impossible to guess what's happening.

[PaulBlay]

Then it said there was another 70 errors of another kind. Now it says:
unresolved external symbol _____ referenced in function ______

I think those are basic Linker errors. It could just mean that there is a *.h, *.c or library file (like winmm.lib)that you need to include in the project but missed. It would probably help to know what the _____'s are.

Here's one quick check you can do ...

Use a search utility (like win-search) to look for your missing symbol ______ in all files in the source code directory (and sub-directories). If there's a file defining them make sure you have included it in the project. (Don't use the default Windows search utility - it sucks).

I found something which said to disable the "treat wchar_t as built-in type" option in C/C++ -> Language. So I did that and it didn't help, it's still giving me the same errors.

I think that would only apply if you are messing around with Unicode or non-English charsets.

Anywho ... now that you're down to just 70 errors maybe you could just put the source code archive up somewhere so other people can have a shifty at it?

P.S. "I've done a lot since 1.0.97. For instance, I created (and fixed) another 618 compile errors." That would make a nice signature quote.

I kindof hoped what I put would be enough, but here's the whole ugly shebang from the error list.

It's kindof odd that it numbers the 70 errors with #6-75

[PaulBlay]

I kindof hoped what I put would be enough, but here's the whole ugly shebang from the error list.

Yeah, apart from the "snprintf" one I got none of those from your source code. I think that either
a) you forgot winmm.lib or
b) these are left-over problems from creating a clr empty project instead of a general empty project.

In any case I'm pretty sure they are down to stuff set in the "Project->Properties" (or maybe from missing a file) not any of your code.

I would suggest deleting the VC++ project folder (it will be a subfolder in \src) and creating it again from scratch, bearing in mind the suggestions above.

Incidentally, you only need "main-win.c" to compile it in Windows, not the other main*.c files.

[PaulBlay]

Back to the original problem - I've done tons of wandering around town killing t's (and one P) and had no crashes at all. So it might be a compiler issue (I had one with Dev-C++) or you might have fixed it without realizing it.

Either that or there is just some specific action that triggers it and I didn't do it.
