There are 3 libraries used for this sketch: “AccelStepper” to control a stepper motor, “Keypad” to map the keys of the keypad and “U8glib” to draw information on the nokia 5110 LCD.
The sketch will not compile and gives the following error message see photo capture.
I'm using the Arduino Mega2560.
Hoping members here can help resolve this issue. Thanks, Ron
Cannot see much of the error message.
Please post the full text of any and all error messages.
Not a picture showing a small piece of one error message out of many.
That's a compile warning (something syntactically valid, but which is felt to be sufficiently bad programming practice that they warn you), not an error. It is compiling successfully - if it doesn't, it won't try to upload, because it would have nothing to upload.
Do you have a string containing "!!!" anywhere in your code? Remove it if so - due to a bootloader bug (fixed long ago, but the bad one is preloaded on many mega2560 clones), this causes the compilation to fail with timeout errors when it gets to it.
You can select the compiler/upload messages and copy/paste them as text - please do that next time you need to post messages like that, not a screenshot. I'm pretty sure there's more above the compiler warnings, for example. And you should be using verbose compiler and upload output (in preferences) when investigating issues (I use it all the time) - which will output a hell of a lot more messages - and for that you absolutely do need to copy/paste it as text.
This sketch is giving me the U8glib library and Timeout issue as shown above. The !!! string is not found
in the code I'm using. My mega2560 is actually a Funduino product. Thanks.

As I said before, The ug8 "error" is not an error, it is a warning - you can ignore it.
Enable verbose upload and post full output (as text).

DrAzzy: Now that I've figured out verbose output, the amount of upload detail in this file is large.
Is this file going to reveal why my sketch couldn't be validated by Arduino? Thank you, Ron

That's verbose compile output, showing a successful compilation. There are no errors, only warnings. Those can be ignored - they do not indicate a problem. It is not unusual for working code to have warnings.
It looks like you did "verify", not "upload" - and no problems were encountered.
As I've said at least twice before, the problem is not with the code. The compilation is completing successfully. Whenever you see it show the total sketch size, that means it compiled successfully.
You said that you can't upload the sketch, and posted screenshots of a timeout error - that is a problem with the upload process, not the compile process. So I need the verbose output of an attempt to upload the sketch to the board, not just verify it.

Yes, I acknowledge no problem with the U8glib library.
I've attached the verbose text file related to an attempt to upload sketch to the mega2560
Hope I've finally got what is needed for a reveal, so to speak.

I can't tell if it's driver problems (it could be - since it sounds like you've never used the board successfully on that system), or hardware problem. Is there anything connected to pins 0 or 1? You can't have anything on those pins when uploading. What serial chip does your mega use? Is the mega showing up as working in device manager?

First time board has been used in my system.
Pins 0 or 1 not connected.
Serial chip don't know.
Device manager indicates (COM10) Arduino/Genuino mega or mega 2560.
Windows has determined the driver software for the Arduino Mega 2560 at (COM10) is up to date.
The RX TX LEDs never light which indicates to me that the Arduino is not transmitting or receiving data from the computer.
L LED blinks constantly.
The green LED is ON indicating Arduino has power.
I will be swapping out this mega2560 for a new board soon and start fresh.
Thank you for your time, help and suggestions.
Ron
