I attempted a "verify" on a sketch; and I had not installed a needed library. Thus, the include file that I referenced in the first line of the sketch did not exist. The Verify immediately exited with a message indicating that it didn't know what was wrong. A better message would have been "Missing include file at line xxx".
Error code message was:
Thanks.
If you enable verbose output during compile, it will tell you

Hi @oktype3tim . Thanks for your valuable feedback. I agree 1000% with your suggestions. The lack of the standard "No such file or directory" error message in this situation was found to be caused by a bug in the Arduino CLI tool the IDE uses under the hood to handle the sketch compilation process. That bug has now been fixed:

**Please check if the PR fulfills these requirements**
- [x] The PR has no du… plicates (please search among the [Pull Requests](https://github.com/arduino/arduino-cli/pulls)x
before creating one)
- [x] The PR follows
[our contributing guidelines](https://arduino.github.io/arduino-cli/latest/CONTRIBUTING/#pull-requests)

* **What kind of change does this PR introduce?**
Fixes an issue with `compile` command and related gRPC function.
- **What is the current behavior?**
If the user tries to compile a Sketch that includes a library that's not installed an error is printed to stderr.
The gRPC interface doesn't show the error at all.
```
$ arduino-cli compile -b arduino:avr:uno /home/alien/Arduino/Blink/Blink.ino --format json
/home/alien/Arduino/Blink/Blink.ino:1:10: fatal error: SD: No such file or directory
#include <SD>
^~~~
compilation terminated.

"compiler_out": "",
"compiler_err": "",
"builder_result": {
"build_path": "/tmp/arduino-sketch-302F70E5AC1B118F7324375770CFA163"
},
"success": false
}
```
* **What is the new behavior?**
Compilation of a Sketch that includes a library not installed now correctly prints the error to the expected error stream.
This also fixes the gRPC function.
```
$ arduino-cli compile -b arduino:avr:uno /home/alien/Arduino/Blink/Blink.ino --format json
{
"compiler_out": "",
"compiler_err": "/home/alien/Arduino/Blink/Blink.ino:1:10: fatal error: SD: No such file or directory\n #include \u003cSD\u003e\n ^~~~\ncompilation terminated.\n",
"builder_result": {

},
"success": false
}
```
- **Does this PR introduce a breaking change, and is
[titled accordingly](https://arduino.github.io/arduino-cli/latest/CONTRIBUTING/#breaking)?**
Nope.

None.

That fix is not yet in Arduino IDE 2.x, but it will be in one of the upcoming releases.
The mysterious "Error: 2 UNKNOWN" part of the error message has since been changed to "Error: 13 INTERNAL", which, if anything, is even worse! But there is a proposal now for improving on that situation here:
