Known script failing now?

monsterthews · January 22, 2021, 9:11pm

In anticipation of TFT display finally maybe working, I pulled out the example scripts I got from Random Nerd. I’ve used them. This is the original, unedited version. My sensor-laden esp-now script was failing for some reason, and i wanted to rewrite it anyway.
But now the tried and tested and built script is failing.

What does “identifier “uint8_t” is unidentified” mean?
I get three of those and an expected expression I haven’t investigated yet. And I’m getting yelled at for comments in a .json.

to wit:

It means, usually, that there is a missing #include <stdint.h> line.

Cheers,
Norm.

Why did it happen?

Why didn’t it happen months ago when I started using this code and built ten programs with it?

normandunbar · January 23, 2021, 6:21am

Hi Joe,

I’m afraid, I have no idea. But it’s not a PlatformIO issue as it is the C++ compiler that is complaining.

A Possible reason could be:

One of the libraries that has included it in the past, no longer does, and has been updated in recent months;

So, in the past while your code explicitly used uint8_t without including stdint.h but a library header you included did use it, your usage was covered.

An update took away the usage from the library and now your use of the int8_t is no longer covered.

Personally, if I need to use these data type, I always cover my donkey and include the header regardless.

I’ve been writing C code, pretty averagely, for 20 plus years and it’s just habit. I’m still not used to having some underlying program do my thinking for me. Like the Arduino IDE does.

Just add the now missing line to the top of the source files that the compiler is complaining about.

Cheers,
Norm.

Comments are not allowed in json files.

monsterthews · January 23, 2021, 9:35pm

Thanks rcohen, but I’m not using the json file. I didn’t open, didn’t read it, didn’t know it was there.
Apparently a train wreck happened.

Yikes!
Bad stuff happened. A lot of this is red, most yellow.

Nothing I can do about artifact in Arduino.h, is there?

normandunbar · January 23, 2021, 11:47pm

Weird stuff happening here Joe. Can you please post the first 25 lines of the Arduino.h file mentioned in the error messages?

From the errors, it looks like it’s seeing a second comment opening within an existing comment. That’s usually not allowed.

Like this:

/* 
 * This is a comment /* and this
 * Is a nested comment, and frowned upon! */
 */

Thanks.

monsterthews · January 29, 2021, 6:28pm

I don’t have access to Arduino.h.

maxgerhardt · January 29, 2021, 6:32pm

It’s right there on your filesystem.

Highly likely something was searched-and-replaced by accident and now the files in there are screwed up.

You can also try to remove the folder

and rebuild, to try it with a fresh version.

monsterthews · January 29, 2021, 6:37pm

The Arduino library has been a huge pain in the butt several times, because there are so many permutations. And some jerk names his new file ‘Arduino’.

I added #include <stdint.h> and got this:

I’m not doing anything with JSON.

I’ve been avoiding Arduino for weeks, because I know these frustrations are back.
I can understand my ignorance’s contributions to my frustrations, but there is no way to every possibly address these frustrations.

I’m not glad it’s happened enough for me to know it’s in the system, not in what I did.

Programming itself doesn’t work right now. How do I know when it’s working again?

So what happens? Does a vandal get in?

Weird stuff indeed. I thought it wasn’t supposed to be weird? Everything is math.

maxgerhardt · January 29, 2021, 6:44pm

the c_cpp_properties.json is autogenerated by PlatformIO and indeed contains comments in the JSON file. This is however handled without warning in the default VSCode JSON engine. It suggest you’ve installed other extensions on top of PlatformIO that hook into the json file processing and thus this error occurrs --> you can try and minimize the installed plugins to just C/C++ by microsoft and PlatformIO .

The second ones should indeed never occurr, but are likely as said a result of a corrupted framework-arduinoespressif32 package which you should be able to restore as written above.

monsterthews · January 30, 2021, 5:23pm

Thank you. So I should not panic.
These behind-the-scenes things are all painful lessons.
You don’t like to be at the mercy of remote machines, but it seems like everyone in this thing is at the mercy of Citizen X’s typing.
Trump’s 300-pound basement slob.
And then there’s the secret inner workings of the complex of applications that come together in this IDE situation.
Great. Now there’s a relationship at the foundation of my hobby.

I will delete that folder.
I was only aware of the libraries in the pio folder.

When it’s called for again, it auto-generates, right?

I don’t need to find anything, do I?
Just zap that folder?

monsterthews · January 30, 2021, 5:50pm

This may be exactly what I went through a few months ago. Everything went kerpluey. Then none of the libraries would load. Now it’s asking for something certainly in a folder inside itself.

This file must be there

Since it isn’t I’d recommend to do a more thorough clean:

Close VSCode
Remove the C:\Users\joema\.platformio\packages\framework-arduinoespressif32 folder
Remove the C:\Users\joema\.platformio\.cache folder
Reopen VSCode and rebuild.

monsterthews · January 30, 2021, 10:40pm

Wow. This is crazy- over 200,000 items in .cache so far. I got sick of waiting for it to stop.

So the framework, the Mama files in the SDK, toolkit section, the framework can spoil.
And PIO will go collect what it’s instructed to collect, and that can 1) be a bad download or 2) be collected poorly.

And there’s nothing I could have done. I just have to keep downloading the esp32 framework until it works?

Is that right?

monsterthews · January 30, 2021, 10:40pm

400,000 items now, up to 4 GB.
What’s that, 10 bytes per file?

Final: 489,267 items, 5.07 GB.
