(...) I appreciate this -- that's what the "Not Quite" is all about. As long as you explain things well, I think this kind of compromise is the right way. (25 years ago, 20-Oct-99, to lugnet.robotics.rcx.nqc)

(...) I tried to do a DJGPP build of binutils and it didn't work for me. I really didn't want to spend more time futzing with the tools, and I was already using Cygwin, so I used one of the precompiled toolsets. I think you are just a lazy typer, (...)

  Sharing variables and using expressions (was Re: NQC 2.0 and some math questions
 
I have discovered a somewhat non-intuitive feature of NQC (in my version, at least, which is pre-2.0) The statement: var = (20 * var) / 21; gets compiled into the following: MUL var, 20 ; var = var * 20 DIV var, 21 ; var = var / 21 rather than the (...)

  legOS limitation
 
Hey, this is a small but frustrating one. This is in legOS 1.7 but I beleive it will still be in 2.0 as it's caused by the 1 priority to a task requirement.

  Re: Hapless WinNT user
 
I'm afraid these are the same errors that were reported with 0.2.1. It would appear that it is looking at a very long and convoluted path which happens to include the standard gcc, not just the cross-compiler. But that is just a guess based on a (...)

  Re: Problems with RCX Robolab and PowerMacs 6400/200 and 5500/225
 
You could try using NQC (or MacNQC) and see if it works any better. I know in the long run you want to get Robolab working, but testing MacNQC would at least separate a Robolab-only problem from more general problems (serial port problems, cables, (...)
