Unable to convert from Int Ptr to Int

I would like to know can this be fixed with NG, this works perfectly with Vanilla BMX btw.For Local Sprite:LTSprite = EachIn SpriteMap.Lists[ Int( Floor( X / SpriteMap.CellWidth ) ) & SpriteMap.XMask, .. Int( Floor( Y / SpriteMap.CellHeight ) ) & SpriteMap.YMask ] Sprite.Draw() Next I'm kind of confused on what has changed, thanks. |

| Hiya, Also, posting any bugs on the github repo would likely get more attention and faster. https://github.com/bmx-ng/bcc https://github.com/bmx-ng/bmx-ng Although NG has moved away from 100% compatibility with the legacy Blitzmax ( it has way more features ), I'm sure Brucey wants it to be 100% backwards compatible. In the meantime, making the assumption that SpriteMap.Lists is a 2 dimension array of integers, have you tried moving the mask expression inside the integer cast expression as opposed to be a part of it... Int(( Floor( X / SpriteMap.CellWidth ) ) & SpriteMap.XMask) , Int(( Floor( Y / SpriteMap.CellHeight ) ) & SpriteMap.YMask) |

| Thanks Dave, but I'm still getting the same error |
| ||
| No probs, I thought it was a bit of a long shot anyway :D I'd raise an issue on the repo. |
| ||
| Hi, one possible scenario is that either CellWidth or Mask fields are defined as Int Ptr's, which legacy Blitzmax converts to Int's but NG does not due to 64-bit awareness. -Henri Ps. Of course I can be completely off :-) |
| ||
| Thanks Henri, Ok now I understand it's related to 64bit awareness and I'm curious on any possible workaround. CellWidth and CellHeight are double and SpriteMap.XMask is integer. |
| ||
| Is there any chance that you post a complete example that reproduces that same bug? |
| ||
| @col Yes, that's the DWLab library that munch posted on an earlier thread, which works on vanilla but not with NG. https://code.google.com/archive/p/dwlab/ Check out 1.4 as I think that's the last version |
| ||
| Using NG v0.78 I just tried real quick and I can't get dwlab.mod to compile either ( obviously ). I get an expression error in a different place to you that I can work around but then I get an EAV during compilation which is rather unhelpful :P It looks like dwlab.mod would be a great candidate for squeezing out some compatibility bugs. |
| ||
| Ah I see. still got 0.70 as I'm failing to build all brl.blitz module with 0.78 (see related post) It looks like dwlab.mod would be a great candidate for squeezing out some compatibility bugs. Agree, it would be a waste to be not able to port and use these existing libraries from Vanilla to NG. |

| @ col use "bmk makemods -v modulenamepart" to compile the module. Then you get in the command prompt the commands used to compile the various file - and so also the line leading to the EAV. Next: - create another BCC-directory, copy the sources in it, copy (if needed) bcc.conf (and adjust to your needs) Open up "bcc.bmx" in MaxIDE, select "debug build" and in "program - command line" you enter the portion after the "bcc[.exe]"-portion of that EAVing command line. Now compile your bcc and upon execution, it should try to compile the module - and when segfaulting, you might have a chance to see what fails. bye Ron |
