Don't know much about the compiler differences (except that I thought most of the 1.1.2->2.9.5 differences would mainly cause compile-time failures, not run-time) but I have compiled every legOS thing I've done (including 0.2.1) with 1.1.2. I have (...) (25 years ago, 15-Nov-99, to lugnet.robotics.rcx.legos)

(...) does this mean legOS will or at least should compile and run without the patch ? if that's true -- what is the actual effect of the patch ? (25 years ago, 15-Nov-99, to lugnet.robotics.rcx.legos)

As I understand it, the patch provides support for interrupts, which, at least from my glance over the code, are necessary only for LNP stuff. (Markus, feel free to correct me on this.) So, it will compile with your "old" cross compiler and provide (...) (25 years ago, 15-Nov-99, to lugnet.robotics.rcx.legos)

(...) In theory, everything should work with an unpatched cross compiler, too. legOS code checks a preprocessor define, CONF_RCX_COMPILER, I think, to determine whether patched or unpatched compilers are used. The problem is, I don't have an (...) (25 years ago, 15-Nov-99, to lugnet.robotics.rcx.legos)

(...) A quick grep of the sources show that only a few things (other than lnp, which depends very heavily on interrupts) need the interrupts- task visualization and sound appear to be the two victims. If you don't need these and don't want to worry (...) (25 years ago, 15-Nov-99, to lugnet.robotics.rcx.legos)

Hi Luis, i got thes egcs-1.1.2 sources today and rebuilt the cross-compiler and legOS and -- it works now. Thanks a lot for your help !! Could you perhaps give me a starting point to get some understanding of how legOS works internally ? (25 years ago, 16-Nov-99, to lugnet.robotics.rcx.legos)

Well, Markus is probably better qualified, but I'm going to try to get to it eventually. Don't bet on it for anytime soon- I seem to be getting less and less freetime, instead of more :( -Luis (...) ###...### Profanity is the one language that all (...)
