Hello everybody I have installed the crosscompiler and legos 2.4 as descriped in the HOWTO. My system is redhat 7.0. The kernel seems to compile just fine, but whenever I try to compile one of the demo programs I get an error. Here is an output from (...) (24 years ago, 18-Oct-00, to lugnet.robotics.rcx.legos)

| | RCX communication
|
|
Hi, (Sorry, my English is not good) I would like to know if it's possible to use legOS (LNP) to get communications between RCXs without the PC, I mean, without an intermediate between the RCXs. And, if it's possible, how can I do that ? I'm using 3 (...) (24 years ago, 17-Oct-00, to lugnet.robotics.rcx.legos)

(...) Ok, thanks. I'll try everything else first, then try this if I get desperate.

| | Memory Usage
|
|
Well, I've gone and run out of memory with my RCX. It manifested itself in a task that refused to run, presumably because the OS couldn't allocate enough memory for its stack. Took a while to track down and was annoying, but it was my own fault for (...) (24 years ago, 14-Oct-00, to lugnet.robotics.rcx.legos)

I've been doing a lot with LNP lately, and I have a few questions. First, the lnpd package I have says in the readme that there is a bug in the legOS kernel with sending LNP packets from multiple tasks. Accordingly, all of my LNP-sending functions (...)
