After making the style.css, the index.html, and the main.cpp files I clicked on the PlatformO:Build check mark.
I get the following error message and I have no idea what it means.
collect2.exe: error: ld returned 1 exit status
*** [.pio\build\esp32doit-devkit-v1\firmware.elf] Error 1
============================== [FAILED] Took 15.54 seconds ===
I Need help.
I have gone back to the beginning of the course and I tried to platformIO build on the blink sketch. I get this same error.
do I need to remove VS and start over. Seems pretty desperate. I have python 3.11 loaded
when I open VS I no longer get the first screen shown in the book. Is there a way to get back to that screen and maybe start over from there?
I managed to get back to the beginning of the course and used all course provided code for each step. Every step worked according to the course program. That includes the “Hello World” example.
When I got back to chapter 2.1 = Web Server – Control Outputs, I used all example files from the course. The only modification I made was to the ssid and password. When I tried to check the program I got the above error again and now the “Hello World” example no longer works but also gives the above error code
Hi.
That must be just the last part of the error: collect2.exe: error: ld returned 1 exit status
*** [.pio\build\esp32doit-devkit-v1\firmware.elf] Error 1
Can you scroll up on the terminal window and share the rest of the error?.
Alternatively, you may want to send a printscreen. To share a picture, upload a photo to google drive or dropbox and then share a link to the file.

Sara

I’m not sure how to save a screen shot but I’ll try to get that too. Ctrl V doesn’t seem to paste screenshots from the clipboard.
Hi.
What ebook
version do you have?
On the latest version (2.2), page 188 addresses that issue.
I suggest following option 2 or option 3 to fix the issue.
If you don’t have the latest eBook version, you can download it here: https://rntlab.com/module-1/welcome-build-web-servers/
Let me know if this fixes the issue.
Regards,
Sara
I don’t know my version but it must be the latest because I just bought the course and have been working on it about two weeks. Somehow I didn’t see several pages right around there. Thanks for the help. I will go back a ways and start this exercise over.
I’m working on 2.3 – WebSocket Web Server chapter. The error came back as usual when I compiled the project for the first time. I mouse over the yellow error message and Ctrl-Click to bring up the WebAuthentication.cpp file and edit the 3 lines of code and then Ctrl-S the changes to save them. Then I went back and recompile as in all previous examples. This time I get error again but it appears to be on a different file. See attached pictures.
I have tried deleting the folder twice and starting completely from scratch using the course provided data files without modifications and the main.cpp file with my credentials but I continue to get this error.
When I go back to earlier lessons I can compile them and they work as designed.
Notice that yellow file above the error message is a different file.

When I try to do the Ctrl-Click on the file I get this file and error message.
