Error include Wire.h

marty_k · January 26, 2026, 6:05pm

Hello everyone.

I am a new user and am struggling to compile my 1st program.

I get this wire.h error: “#include nested too deeply”, which github says means a name clash or a circular include. So on their suggestion, I wrote a new empty sketch with wire.h and I get the same error.

#include <wire.h>

void setup() {}

void loop() {}

Anybody? TIA

#include <wire.h>

Check the name of the library very carefully. Is it called wire or Wire ?

marty_k · January 26, 2026, 6:34pm

Yes, I thought of that too. But then it just wouldn’t find the file, right?

sonofcy · January 26, 2026, 6:43pm

It would if there were a wire.h somewhere in your include path including your aketch folder and all sub-folders. Do a search for wire.h starting at your Arduino folder.

Yes there is another one further up the tree. I renamed it but made no difference.

Thanks

Renamed what?
BTW, what board have you selected, I get a missing error with my system

sonofcy · January 26, 2026, 7:08pm

What does 'up the tree' mean. Tell us the exact full path and filename. Did you renname the file which is wrong and will cause you future problems, or did you fix your sketch as post 2 mentioned.

xfpd · January 26, 2026, 7:12pm

Your error says there is a difference. Find the re-name you did and un-re-name it. Then, in your minimal sketch use uppercase-W "Wire.h"

marty_k · January 26, 2026, 7:24pm

Yes, the other file is uppercase W and its contents are totally different. So I changed to Wire.h and still no difference.

marty_k · January 26, 2026, 7:28pm

My board is a Sparkfun RedboardPlus. I’ve selected Arduino UNO like they said to do.

marty_k · January 26, 2026, 7:30pm

Where did I say “there is a difference”?

xfpd · January 26, 2026, 7:32pm

No. Do not change standard library filenames. They have their spelling and case for a reason. Un-do what you did. The problem stems from your use of the wrong library.

xfpd · January 26, 2026, 7:33pm

First post.

xfpd · January 26, 2026, 7:44pm

Your "wire.h"

System "Wire.h"

Ok, UNO is correct.
There is confusion with your use of the word 'rename'. That normally means to rename a file. DO NOT DO THAT and if you did rename it back.
Simply change the lower case w in wire.h to Wire.h. The OS is case sensitive.
Good use of <>, that means search the system libraries only and is correct. I tried these steps and do not get your error, it compiles clean.

[edit] Disregard the following... the error refers to library line 25...

What code is on lines 1 through 24?

         1    1  1
1...5....0....5..8
#include <Wire.h>

A previous version of IDE had problems with compiling unsaved sketches, and adding/removing lines to/from the unsaved sketch.

marty_k · January 26, 2026, 8:09pm

Lines 1 to 23 is legal mumbo-jumbo.

Line 24 is blank

xfpd · January 26, 2026, 8:17pm

Is the sketch in question opened from a zipped file, or without a folder, and unsaved?

marty_k · January 26, 2026, 8:22pm

Why would I zip a 51 byte file?
All sketches have to be in their corresponding folder.
