fatal error ESP8266WiFi.h no such file or directory

[flirt]

I want to turn my esp8266 into access point so that i would able to connect directly to it.i use the following sketch but when i select GENERIC module ESP8266 from menu the two libraries which is ESP8266WiFi.h and #include ESP8266WebServer.h become available but at this point i was unable to upload sketch to arduino.Also when i select Board as arduino uno (Which i have really) and then what to upload then the above two files becomes unavailable and says fatal error no such file...no idea what to do next...Thanks in advance for kind attention.

"i use the following sketch" That's nice..what sketch might that be? Anyway it sounds like you have some sort of local install / setup problem. The best I can offer is you start again here: https://github.com/esp8266/Arduino/blob/master/README.md#installing-with-boards-manager

Which Arduino version are you using? The latest that that worked for me was 1.6.9, any higher it generates compile errors. Official is on 1.6.8, perhaps try downgrading to it if you are using a higher Arduino Version

I have this installed and working in v1.8.1 of the Arduino IDE here. This is their latest version today and a test compile of one of the included sample sketches works without any build issues. This is running on Linux Mint 18.1.

I'm not a fan of the Arduino IDE and I don't actually use it..but that's another story.

[lmk1988]

:( Sadly I just tried 1.8.1, it doesn't work for me. It still have compile errors but due to external .h files

[bebo-dot-dev]

take a look at the screenshots I posted in this other issue: https://github.com/esp8266/Arduino/issues/2993#issuecomment-282806813

if that doesn't help, I suggest you post your own screenshots

Hi dear I'm use the blynk library,stand alone program but there is an error when I verify the program , c/users/arduino /libraries............. no such file or directory

[Roanb89]

Im having a similar error "fatal error: data.h: No such file or directory" then under, it says #include "data.h"

There is no compilation issue using the Arduino IDE 1.8.4 and with latest git core. This as either user error or installation error. For assistance, please refer to esp8266.com or stackoverflow. Closing.

I love using Arduino IDE but I hate it when someone is getting an error, but people like devyte just say that it is a user or installation error. We are asking for help with the error, not asking what it is not. I am trying to compile a sketch and I keep getting a "wl_definitions.h: No such file or directory" even though when I try to install the library that has the file, Arduino tells me that it is already installed. Normally if I get something like this I just find the library and install it and that fixes it, but not with this. Does anyone have any ideas about what is going on? I am using Arduino IDE 1.8.13 on Windows 10 and I have my board selected as Modemcu32s. It is an esp-wroom-32 developmental board. Maybe I have the wrong board selected but I don't know. It worked fine when I was programming it to work with Alexa and some relays. By the way, this is the full error line:

Used: C:\Users\13212\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.6\libraries\WiFi C:\Users\13212\Documents\Arduino\Sketches\libraries\ESP8266wifi\src/ESP8266WiFi.h:28:28: fatal error: wl_definitions.h: No such file or directory Not used: C:\Program Files (x86)\Arduino\libraries\WiFi compilation terminated. exit status 1 Error compiling for board NodeMCU-32S.

Lots of users error indeed in your post:

• You are using an esp32 but you're in the esp8266 arduino core issue tracker.
• This issue tracker is meant to track the esp8266 arduino core issue and not meant to help users with installation issue, except when the issue is because of the arduino core installer - which is not the case here. The reason is that it'd be too much work for the people responsible for the repo. User errors are generally well managed in forum like stack overflow arduino section for example, or esp8266.com for esp8266 users.
• If there was a real issue with wl_definitions.h, nobody could use this core.
• This is a closed issue. If there's something wrong, please open a new issue.

We hope you'll be able to use your ESP32 with the right arduino core. You need to select the right board in the Arduino IDE tools menu. You seem to be using the esp8266 specific libraries with an esp32 installation. I personally don't know how this can happen. I'd advise you to delete your arduino installation including the "arduino15" directory, and start over from scratch.

Either its a case of picking the right board definition or your system is real messed up and its time to start from scratch

Ok, thanks.

Can compile fine using VS code extension but using arduino IDE I get the same same error mentioned above, this seems to be some kind of problem with the IDE and how it includes libraries, VS code extension seems to find .arduino15/packages/esp8266/hardware/esp8266/3.0.2/cores/esp8266/wl_definitions.h just fine.
