64 bit Irrlicht.

To use Irrlicht on a 64 bit system, does Irrlicht have to be recompiled for 64 bit? I just got a new computer that's 64 bit. I've been trying to get ready for another release of EditIrr, but I ran into a problem that I had heard users got before. The person who told me about it was on 64 bit too. It works perfect on my 32 bit machine though. It's on device->getSceneManager() calls that it's crashing... Could it be trying to give me a 32 bit pointer?

No I use irrlicht on 64 bit system all the time and I have no problems. I'm thinking your problem is being caused by something else. Maybe you could post some code or something.

Yeah, usually all 32bit programs should run fine in a 64bit environment.

I'm using a .lib and .dll that were compiled on a 32 bit system, on my 64 bit system. They're just the ones in the Irrlicht download.

You can not mix 32 and 64-bit code. If your program is 32-bit, all DLLs that it uses must also be 32-bit. That is the only restriction. Other than that, 32-bit code works perfectly fine on a 64-bit system. If you are getting crashing issues, make sure you don't have any old DLL files anywhere. If you are custom compiling Irrlicht, do a full rebuild and make sure you are using the correct Irrlicht.dll file. A lot of times the crash errors are because somebody has an old Irrlicht.dll file that they are accidentally using.

If DLLs are already compiled then you shouldn't have trouble using them in a 64bit program even if its 32bit right?

32 bit can run in 64 bit fine. I'm 99% sure your problem is something else.
Edit: I have actually used your program on my 64 bit machine and it works fine. Is there something special I have to do to reproduce the error?

If you try to add a scene node or animator it doesn't work. Code execution never goes beyonde the smgr = Device->getSceneManager(); line. I think I'm getting a bad pointer on my 64 bit machine because it works perfect on my notebook. Here's the libraries used:
Irrlicht (tried with 32 bit and tried recompiling for 64 bit),
LUA (compiled on 32 bit I think)
ToLUA (I think it was compiled on 32 bit too)
Boost (No idea what that got compiled on)
wxWidgets (32 bit I think).
As you can see it's mostly 32 bit. Is there a way to get Code::Blocks and GCC to compile 32 bit programs on a 64 bit machine?

Works for me. Animators work fine and I can add some scene nodes. When I try to add some of the nodes nothing happens(I assume it's because you haven't programmed it yet) and when I try to add an animated mesh the mesh doesn't show up, but nothing crashes. I am using Win7 64 bit.

It only happens when you compile it on a 64 bit machine. If you use the binary from sourceforge it works fine.

I see, you now ran into the same problem as me.
(I was the person that first had the problem)
I also tried tons of things to fix it but nothing worked.
I really prefer it IrrEdit, so I'd love it if there's some fix for this.

I tried compiling this in 32bit with 32bit libs etc for all dependencies, still nothing.
I also then tried compiling on a 32bit Win XP machine of mine and somehow got the same issue.

butting in again

For all those using Windows 7 – check that the folder where the art files are, are not protected with read-only properties by another 'user' (even if you are the only one using it)
I found that out when I wrote simple msi files and they refused to compile. I was logged in as Administrator and the folders where created by another user (me as BetaTester), so they did not link properly.

To save myself from grieve, I simply moved all my work from C:\ to C:\Users\MyName\ and no problems from then on. If your development is too advanced ( I just started ) trace the actions with something like Process Monitor and set the needed folders manually to Share - Read/Write to your AdminName. I tried to unlock all folders

this was interesting, lucky me there was a restore point.
