1) unpack and patch everything as described above and then run make until the error occurs.

2) Then edit the file compiler/lexer.cpp on line 1860 which looks like :

extern int isatty YY_PROTO(( int ));

and change this to

extern “C” int isatty YY_PROTO(( int ));

save and quit your editor.
3) run make again

Should now produce a workin nqc binary.

Hope this works for you as it worked for me, regards

Thanks for the helpful instructions. I would like to pass along one suggestion – it may be a quirk of my particular set-up, but I eventually found that the only way I could get nqc to communicate with the tower was to rename /dev/usb/legousbtower1 to /dev/usb/legousbtower0. Presumably the package I am using (nqc_3.1.r6-1_amd64.deb) has a requirement for that hard-coded in somewhere. That solved the problem. It may be worth a try to anyone who has a loaded tower driver and a working nqc, has already tried chmod 666 and changing file ownership, but keeps getting the message (as I did) “could not open serial port of usb device.”

BTW – I had trouble compiling nqc, so here’s the link to the package, in case anyone wants to try it: http://packages.ubuntu.com/uk/precise/amd64/nqc/download

Cheers,

Tjanks for that great post, I’m really looking forward to be able to program my RCXs (2.0 &1.0)

Everything goes good until I run the patches. I got this
“patch -p0 < nqc-01-Linux_usb_and_tcp.diff
patching file nqc-3.1.r6/Makefile
Reversed (or previously applied) patch detected! Assume -R? [n]
Apply anyway? [n]
Skipping patch.
5 out of 5 hunks ignored — saving rejects to file nqc-3.1.r6/Makefile.rej
patching file nqc-3.1.r6/nqc/nqc.cpp"

It comes few times and I can only say "no"

After few times I come back to the normal command line.

Then I ran: cd nqc-3.1.r6
make

And got the stacy looking lines. But at the end it says this:
"compiler/lexer.o: dans la fonction « yy_init_buffer(yy_buffer_state*, _IO_FILE*) »:
lexer.cpp:(.text+0x1c46): référence indéfinie vers « isatty(int) »
collect2: error: ld returned 1 exit status
make: *** [bin/nqc] Erreur 1"

Do you have any idea what I could do to solve this?

By the way I already managed to put the firmware on my RCX, I just need the patch between NQC and my USBtower.

Thank you in advance 🙂

Justin

Please run the following three commands in your terminal.


sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential


That should solve it

thanks for the guide. I love to see a solution for this. Unfortunately I got stuck on the make command as you can see below. I am not sure how to continue? Thanks

After speading days trying to get my old RCX 2.0 back up and running on anything, i managed to get the old RIS software installed and I think working on Linux Minth 16 through WineHQ. Except the software doesn’t seem to recognize the USB tower.

I know the town works because I was able to use it on windows xp until I rebooted the laptop. This seems to be a known problem — RIS will work once on XP then never again after a reboot.

So the tower works. The USB ports work. The port is sending power to the tower, as it does light green when first connected. But after rebuilding the PC with Linux Mint I can’t seem to communicate with the tower anymore.

Is there anyway to just quickly test the connection in Linux?
