Mike, As recommended by others in this thread I contacted Lego Dacta and they sent me (free of charge) a CD-ROM with the 2.5.1 upgrade on it. This can only be applied to an installed copy of 2.5.0. I have not found the 2.5.1 upgrade anywhere on the (...) (23 years ago, 3-Oct-02, to lugnet.robotics.rcx.robolab, lugnet.dacta)

I grow confused about all this. Can you tell me how to get 2.5.1 from a patch/update off the net? Alternatively, can you tell me who to contact in the UK (or for the UK) to get the update files please? Mike Reddy, Senior Lecturer -- Web: (URL) (...)

I, too, have been at it for three weeks. gcc and bintools build OK under cygwin, but when it gets to the cross-compiler, the whole make process craps out. The compile fails because some of the cross-compiler sources are (complaining about) missing (...) (23 years ago, 3-Oct-02, to lugnet.robotics.rcx.legos)
