Hi,
I hope you will all forgive me for my impudence?
Rather than repeat all the information again, I wonder if you could scan this thread for me. And hopefully the linked log files. NHD-0216AW-IB3 with Arduino Uno Code example? in the hope that you can point me in the right direction.
It may be quicker to start at the bottom and craw up?
Best regards, Martin
It is rather impudent.
You have not even bothered to tell us what the Thread is about or why you are interested in it, or what exactly you want help with.
It may surprise you to know that I am even lazier than you are.

Post your code HERE.
Post links to non-standard libraries HERE.
Post error messages HERE.
It appears, though, as though you have linker issues, not compiler issues. This suggests to me that you have the header file for a class, but not the source code that goes with it.

Thank you Paul for the tips. I'd love to post code, if it would help. It is only the stuff I was trying to avoid repeating...

I'm sure you don't realty mean that I should post the verbose log HERE? - it's 30kb!
I have posted it at the link above.
PaulS:
It appears, though, as though you have linker issues, not compiler issues. This suggests to me that you have the header file for a class, but not the source code that goes with it.
The Library that I was given by Newhaven Displays has two files: OLedI2C.ccp & OLedI2C.h. I guess that the .h is the class header & the .ccp is the class source code that goes with it? Do I need more?
Best regards, Martin

Where have you installed the files ?
Hi UKHeliBob,
These are the points (copied from my Newhaven Thread) that look at this possibility:
Hi Chris, [...] Looking at the "Library in the wrong location" first.
While yes, it could be. But this is the results of this line of inquiry....
I have three library locations (don't know why?), they are:
a) /home/mprowe/Arduino/libraries/
b) /home/mprowe/.arduino15/packages/arduino/hardware/avr/1.6.18/libraries/
c) /opt/arduino-1.8.0/libraries/
For testing purposes only, I have put your library in all three locations - with a customized library.properties file (so that I can get the libraries location from within the Arduino IDE).
The log output (below) shows that it has found all three & is using the copy at (2.b) see lines 86 to 89. This is alongside the wire library.

93 Error compiling for board Arduino/Genuino Uno.Compiling with only one copy of the OLedI2C in each location. First run with OLedI2C in 2.a), second run with OLedI2C in 2.b) and finally with OLedI2C in location 2.c). This still results in a compilation error?
To try and avoid any OS dependency’s (NHD are using Windows, & I use Linux), I have done the same using the official web based workbench, Arduino Create. Yet again, no compilation success!! I have posted the verbose error log here http://www.mpr75.talktalk.net/. At my (low-level) of understanding, the output logs from all three OS'ies (Linux, Windows & web based) seem similar. To me, it is suggesting a path-resolution problem in OLedI2C.ccp or its dependencies?
And this is the link to Non-Standard Libraries: http://www.mpr75.talktalk.net/
That does not appear to link to the library. There appear to be only log files at that address.
Third party libraries are usually installed in the libraries folder of your sketch directory and #included in your program using < and > round the full name of the header file.
Without your program code and libraries it is difficult to offer advice and impossible to try to compile the code.
- I have three library locations (don't know why?), they are:
a) /home/mprowe/Arduino/libraries/
b) /home/mprowe/.arduino15/packages/arduino/hardware/avr/1.6.18/libraries/
c) /opt/arduino-1.8.0/libraries/
Only a is correct. Delete the other two copies COMPLETELY.
Hi PaulS,
Only a is correct.
Yes, I understand that is the correct configuration. I did say it was "For testing only". I also went on to say that even with a single copy in location a), it would not compile!
That does not appear to link to the library.
Opps.... Sorry. They are there now. I have also uploaded oled-test.ino.
It would be great if your intention was to try compiling at your end.
