Please help me. I have a project that I have been working on for a long time. The project contains more than 10,000 lines of code. A few days ago, everything was working fine; I was using IDE 2.0.6 (ESP32 dev board). Now, when I try to verify or upload the sketch, it takes more than 20 minutes and I also get errors that I did not get before, even though I haven't changed the project. I have tried on several different computers and the same thing happens. On the same computer, I also have IDE 1.8x, where verifying the sketch also takes a very long time, more than 15 minutes, but I don't get any errors and I can upload the sketch to the ESP32.
Before this issue, the time to verify the sketch was about 3 minutes.
Hi @barboxxx.
Can you think of anything that changed between the last time it was "working fine" and the first time you noticed a problem?
Why do you say "was"? Are you using something different now than what you were using before?
Please provide a detailed description of what you mean by this. There has never been a 2.0.6 version of Arduino IDE.
I'm going to ask you to provide the full output from a compilation during which these errors occur.
This procedure is not intended to solve the problem. The purpose is to gather more information.
Please do this:
- Open your project in Arduino IDE.
- Select Sketch > Verify/Compile from the Arduino IDE menus.
- Wait for the compilation to fail.
- You will see a "Compilation error: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button on that notification.
- Open a forum reply here by clicking the "Reply" button.
- Click the
<CODE/>icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
- Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the compilation output into the code block. - Move the cursor outside of the code block markup before you add any additional text to your reply.
- Click the "Reply" button to post the output.
In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a .txt file and then attach that file to a reply here:
- Open any text editor program.
- Paste the copied output into the text editor.
- Save the file in
.txtformat. - Open a forum reply here by clicking the "Reply" button.
- Click the "Upload" icon (
) on the post composer toolbar:
The "Open" dialog will open. - Select the
.txtfile you saved from the "Open" dialog. - Click the "Open" button.
The dialog will close. - Click the "Reply" button to publish the post.
Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the .txt file onto the post composer field to attach it.
Two of my favorite subjects: slow compiling and ESP32 platform/libraries.
Version 3.0.0 of arduino-esp32 was released five days ago, and has several breaking changes from v2 (the latest is currently 2.0.17, and there was a 2.0.6 from Dec '22 It is likely baked into your Board platform, directly or indirectly.
You can find your Board in the Boards Manager, see if the "Installed" version is 3.something; you can change it back to the latest 2.something, or to 2.0.6 if it is still listed.
IDE 2.txt (5.1 MB)
i tried to downgrade board manager but no success, also tried tu update IDE to newest
This error is caused by a syntax error at line 318 of your sketch.
You must specify a data type when you declare a variable.
Change line 318 of your sketch from this:
const WDT_TIMEOUT = 30;
To this:
const int WDT_TIMEOUT = 30;
After that, compile the sketch again. Hopefully this time it will be successful. If not, post the new output, just as you did before and we'll take another look.
