Hi, thanks for the letting me know. I'll look at a fix. In the mean time, could you try these links instead? You can get an offline installer and source code for Qt 5.12.12 here: www.qt.io/offline-installers, and here: download.qt.io/archive/qt/5.12/5.12.12/. Please note! I had to use 5.12.3 when I tried, I couldn't get 5.12.12, or higher than 5.12.3, to work, some more info: heavybaremetal.com/index.php/blog/6-how-to-cross-compile-qt-5-for-raspberry-pi-3#h52skelb92cp1u42gydadmhkmpwp0u4 5.12.3 offline installer and source available here: download.qt.io/archive/qt/5.12/5.12.3/ Anywhere in commands on the website, you will have to replace download.qt.io/official/ with download.qt.io/archive

@@heavybaremetal8682 Thanks for your quick answer!😀 In short, it works now! I will post my long answer (and a few other points) as a fresh comment; in case someone else is interested.

@@berndwacke7083 Could you post your long answer? I am stuck at "qt requires c++11 support" too

The Arduino plugin for VSCode solves 60-70% of these problems, and provides customizability. The limits of the libraries and language are the real limits.

Hi, did you follow all the commands on the linked website? It seems cmake is not installed. What OS are you using for running Qt?

Thanks for the comment. Yes the switch method could just call functions. The table of function pointers method is just an alternative to the switch case, but it can be easier to modify and keep track of. Yes dealing with changes is always the hardest part, but making code easy to modify from the start is best. Happy coding!

Are u using the Debian Bullseye OS on your Raspberry Pi ? if yes, then u should probably get the Buster instead so that it works !

@@cedric6100 Hi, I just had the same issue on Raspbian/Debian Bullseye. Seems that Qt 4 is now obsolete, and thus no longer available as a package. I just left it out, since I'm not using Qt 4 anyway. No issues encountered.

Thanks very much fro confirming it still works! I hope it was helpful!

Hi John, thank you for your comment, I'm sorry for the delay in replying. For your system a state machine may not be needed, but I'm not sure. It sounds more like data gathering, so a more suitable design might be to gather the data on a clock tick (similar to how the traffic light system only does something when the next time is reached), then package the data up and send it over your radio link. If you continually collect data but only send it say once a second all in one go, then a state machine might be suitable, as there are clearly defined separate states: collect data, send data. But this could also be done just be filling a buffer, then sending once the buffer if full. I hope this helps!

@@heavybaremetal8682 Yes, it is data gathering. And I guess I'll follow your advice (filling a buffer). Thank you for the reply!

​@@heavybaremetal8682 but if you're trained to gather data at and use the data I think a switch case would be better because I did some things a while back and I would crash the CPU. on the Arduino.

Some of the syncs don't send a lot of data. Did you get an error? Carry on anyway it should work. Thanks for the comment!

@@heavybaremetal8682Thnx for yur reply man! I Started all over again and have the same problem again... sigh :x Hmmm okay, but at 16:05 when you enter "rsync -avz pi@$PI_IP:/lib sysroot" a-lot of data is being transfered from the pi to the vm, like lib/arm-linuxgnueabihf folder etc. With that command i only get this: utracer@utracer:~/raspi$ rsync -avz pi@$PI_IP:/lib sysroot receiving incremental file list lib -> usr/lib sent 27 bytes received 57 bytes 168.00 bytes/sec total size is 7 speedup is 0.08 something is going completly wrong and it driving me nuts.. I ignored it yesterday also but with making the install it went into errors & missing files.... SoI guess it's due this line "rsync -avz pi@$PI_IP:/lib sysroot"

@@heavybaremetal8682 I guess you were right! i finally managed it to compile the program and run the analog clock on the pi! yeahhhh, gotta go to work, tonight i'll carry on with Building and debugging with Qt Creator

@@DJDavo013 Congratulations! What did you do in the end? Was there something missing in the guide? Thank you very much for letting me know how it went!

@@heavybaremetal8682 I can't exactly tell what went wrong... I had sum issues when i restarted the VM & Pi & tried to rsync after generating a new ssh it worked export PI_IP=<ip adress> ssh-keygen ssh-copy-id pi@$PI_IP rsync -avz pi@$PI_IP:/lib sysroot And this one also: Now we need to let the Pi know about these new libraries. Open an SSH into the Pi, with: ssh pi@<PI IP address> i did this in my VM ssh But i think you should let the manual as it is... I made it myself confusing lol Linux can be quite a pain sometimes, i'm just a rookie as it come to linux Thanks for make it happen! I'm not there yet lol still have to do the rest (Building and debugging) but i had to work and got home late... my goal is to install www.bmamps.com/uTracer/utmax_linux.zip and run it on the pi, the soft has been written with qt, and i'm very happy with your tutorial man!

Thank you very much for your kind comment! I'm glad it helped! I was in the exact same situation which is why I made this video. What kind of videos would you like to see? I've been thinking of making a series on embedded TDD (Test Driver Development), writing unit tests FIRST, then the code to make the tests pass. That's how I write code in industry, very easy to add new functionality when you have a complete suite of tests to prove you haven't broken anything else!

Thank you sir! Your milling video looks very interesting! Thank you for the kind offer, I'll remember it! Very impressive tolerances. I've got an original Makerbot Replicator, great for quick prototypes, but not the most reliable or accurate!

Hi Jorge, thanks for your comment. See the comment above: "For a graphical program, you'll have to execute it on the Pi itself, otherwise you'll get no graphical output. Copy across, then run from the Pi You may have to be build the Qt svg module, and copy the libs over to the Pi, details near the end of the video/website guide. Let me know how you get on!" Once copied over, you should be able to run graphical programs from the Pi directly. Just find them and double click. There are ways to remotely execute a GUI program, but can be quite complicated. Look into X redirection over a network if that's what you want.

@@heavybaremetal8682 I got it working by exporting some environmental variables from the pi to my vm. You can do the same on the QT creator and it runs on the pi from my vm. Also I did not set the mspek and it still works? IDK lol

Hi, thanks for the question. How are you running/copying the program? What happened with the analogue clock example? heavybaremetal.com/index.php/blog/6-how-to-cross-compile-qt-5-for-raspberry-pi-3#h61skelb96xplx7j2frwiv9mbo5df7 For a graphical program, you'll have to execute it on the Pi itself, otherwise you'll get no graphical output.

Same here. Doesn't work. Heavebaremetal, can you fix? Going through steps is hard just using video. Thanks!!

Hi Jef, website is fixed now, spam bots got past the comment captcha and overloaded it with 100,000+ comments! Sorry for the outage!

@@heavybaremetal8682 works now, thx
