I keep getting a missing file compile error:
=====================================================================
#include <Adafruit_TFTLCD.h> // Hardware-specific library
But when I look in the c\documents\Aduino\libraries folder, I see both the Adafruit_TFTLCD.h and the Adafruit_TFTLCD.cpp files; What am I missing?
Thanks!
Showing the complete output of a compile attempt with verbose output enabled, formatted with the <CODE/> tool to make it readable, might make it possible to offer a diagnosis.

Make sure case is identical. Also try " .... " rather than < ... >
Also, an aside, but I can't help but notice you have .INO in the folder name therefore.INO.ino for the sketch.
Show the full verbose error log in code tags.
You might have non-ascii characters in your file path. Can you post a screenshot of file → preferences in the IDE?
The below shows one with the problem (marked in red)
Thanks for the tip!
Here is the compile error in verbose mode
(still not sure what it’s telling me);

What is the folder Adafruit_TFTLCD_files? Did you create it yourself?
If the library TFTLCD-Library was installed correctly, Adafruit_TFTLCD_Library should be created under the libraries folder like this:
C:\Users\pip\Documents\Arduino\libraries\Adafruit_TFTLCD_Library

Just to be sure, try moving Adafruit_TFTLCD_files to your desktop and reinstalling TFTLCD-Library from the library manager.
Then open an example from "File > Examples > Adafruit TFTLCD Library " and make sure it compiles correctly.

Looks like (library) files were moved or installed elsewhere, possibly if you unzipped a file containing libraries.

iamiretheo:
`myLCD-EMG.INO.ino
The .INO.ino does not look right.
Also the"-" special character in the file name.
Not sure why it saved itself by including “.ino” in the file name, any ideas?
When you saved the sketch, you called it myLCD-EMG.INO instead of myLCD-EMG .
Thanks for bringing this to our attention @xfpd . I submitted a formal bug report to the Arduino developers on your behalf:
opened 02:16AM - 10 Nov 25 UTC
topic: code
type: imperfection
topic: build-process
### Describe the problem
During sketch compilation, if Arduino CLI finds a fold… er in a libraries folder that does not contain a valid Arduino library it displays a message to notify the user in the verbose output:
```text
loading library from C:\Users\per\Documents\Arduino\libraries\FooLib: invalid library: no header files found
```
🐛 If multiple such libraries are found, the messages are printed all on one line instead of a newline being added between each message.
### To reproduce
```text
$ export ARDUINO_DIRECTORIES_USER="/tmp/FooSketchbook"
$ arduino-cli core install arduino:avr
[...]
$ mkdir -p "$ARDUINO_DIRECTORIES_USER/libraries/FooLib"
$ mkdir "$ARDUINO_DIRECTORIES_USER/libraries/BarLib"
$ arduino-cli sketch new "$ARDUINO_DIRECTORIES_USER/FooSketch"
[...]
$ arduino-cli compile --fqbn arduino:avr:uno "$ARDUINO_DIRECTORIES_USER/FooSketch" --verbose

### Expected behavior
Each of the "invalid library" messages are printed on a separate line.
For example:
```text

loading library from C:\Users\per\AppData\Local\Temp\FooSketchbook\libraries\FooLib: invalid library: no header files found

so in order to get a clean start, I renamed my arduino floder and created a new arduino folder. Then I copied my script from the old folder and copied it to the new arduino folder. I opened the arduino IDE and opened my script. Then I managed libraries by including zip libraries, but I am sti;; getting thesese compile errors"

And now I am at wits end trying to figure out ho to get this to work.
Can anyone please help me to figure this out ?
Thanks
I asked for your program.
And why did you add ZIP libraries? And not install libraries the usual way via the library manager (except for those that don't exist in there).
I guess you did not install the Adafruit_TFTLCD library.
