Hi, I checked into the CVS repository some changes today. They include: A) a fix to util/dll-src/Makefile to reference ../../kernel/lnp.c, so a symbolic link or copy is not required. B) small changes to various makefiles to get c++ support working (...) (23 years ago, 21-May-01, to lugnet.robotics.rcx.legos)

Hi, Sorry that I've been AWOL! Attached is a set of patches you can apply to the 2.5 distribution to clean up most of the make process. You will still have to correctly specify the TOOLPREFIX in Makefile.common, or via the make command line. You can (...) (23 years ago, 21-May-01, to lugnet.robotics.rcx.legos)

Is c++ supported in legOs2.5 ? We've been unable to compile even the demos! (I already posted about that) Please give us a voice! thanks Ciao, Vittorio (23 years ago, 20-May-01, to lugnet.robotics.rcx.legos)

Hi all, I'm new to legos and am having some problems loading programs. I have searched the news pages for my particular error and there are some that are close but not exactly. I hope someone can help because I am currently "dead in the water". Here (...) (23 years ago, 19-May-01, to lugnet.robotics.rcx.legos)

Hi there! (...) 0th law of computer science: NEVER use == on floats; it simply doesn't work as expected. In most cases a value cannot be exactly represented as a float variable; so MOST comparisons for equality WILL fail. (this is NOT an issue of (...)

(...) Thanks! But rather than do things for a single user I opted for: chmod 666 ttyS0 If I'm not mistaken, this will give every user access to Serial port 0 (comm 1).

Hello, The first thing I have ever installed on a *nix platform was legOS on my recently (last week) converted Redhat Linux PC. I didn't really know how this sort of thing is supposed to work, so I did the whole install as root. Of course after I (...) (23 years ago, 15-May-01, to lugnet.robotics.rcx.legos)

I agree with most of Luis statement. I've worked for three years in the embedded software development (for cars), and I think it's quite dangerous to have RCX functions with the same name that Unix ones, because they don't do the same thing.

I'm actually on my way to my baccalaureate ceremony right now, but I do want to say that I feel very strongly that API changes for the sake of API changes should not be checked in. The current API, while not always intuitive, is well documented and (...) (23 years ago, 12-May-01, to lugnet.robotics.rcx.legos)

(...) I don't imagine that these changes will increase memory usage much, since they are largely just re-working existing features. I will look into the memory usage before releasing, though.

My only concern with these proposed changes is possible increased memory usage. Encapsulation, error reporting, thread synchronisation etc are nice; but with just 32k of RAM I would question whether these are appropriate for some applications. For (...)

In using legOS, I've found that many of the design decisions seem somewhat backwards, and I think that this is due to a desire to keep the interface as similar as possible to NQC.
