(...) well, i got it and compiled everything using linux 2.2.13 and glibc 2.01. My native compiler is gcc 2.95.1, for cross compiling i built gcc 2.95.2, after applying the rcx-interrupt patch. compiling the dll and makelx utilities was a little (...)

Hi Martin, the FD_ZERO bug sounds interesting. Maybe there's a way to work around this issue in a more portable way? Like, remove /usr/include from the Makefile and hope for the best? The debugging output shows that the host is sending packets and (...) (25 years ago, 9-Nov-99, to lugnet.robotics.rcx.legos)

Hi Markus, sorry for the delayed response, but finally i'm back: (...) i found a way that may be somewhat cleaner, by separating the lnp related header files needed by the utilities from the libc stuff: created a directory in legOS/include named (...)

Hi, if I am not wrong, I have a problem similar to Martin's: When I load the legOS-0.2.2 kernel to the RCX, the kernel dies leaving "on -" on the LCD. It doesn't accept any key input, only removing the batteries helps. When I nevertheless try to (...) (25 years ago, 14-Nov-99, to lugnet.robotics.rcx.legos)

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.

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.

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)
