Example BASIC gives compilation errors

[grumpy-gnome]

Trying to verify the basic example sketch and I get the following errors:

Using library Flash at version 1.0.1 in folder: C:\Users\jemim\Documents\Dev\arduino\libraries\Flash exit status 1 Error compiling for board Arduino/Genuino Uno.`

Any pointers would be appreciated

[Lurgainn]

Same error here. A temporary workaround is to compile with 1.6.21 version of avr boards manager.

[grumpy-gnome]

Thanks for the pointer.

Unfortunately on my set up it still gives compile errors, although not a catastrophic compiler error as before. I'll just have to stop being lazy and create my own code to manage PROGMEM stuff. It'll help me understand what's going on anyway.

Thanks again

[Lurgainn]

I guess that the problem arise from the fact that from 1.6.22 version it's enforced the condition that every PROGMEM statement must be 'const'. I hope that the author of this library will adapt the code because flash library is SO MUCH MORE easy to use vs. original PROGMEM.

[schinken]

Can anyone try that out? https://github.com/schinken/Flash/commit/4d2ce7eb5a29326c0c2f1c1506906673a79c05a4

[Lurgainn]

With the modified Flash.h I have the same error (even if with the 'const' keyword) :(

[per1234]

Here's a workaround:

1. Tools > Board > Boards Manager
2. Wait for downloads to finish.
3. When you move the mouse pointer over "Arduino AVR Boards", you will see a "Select version" dropdown menu appear. Select "1.6.21".
4. Click "Install".
5. Wait for installation to finish.
6. Click "Close".

Due to a bug, this workaround doesn't work with Arduino IDE 1.8.6, but it will work with any other version of the Arduino IDE.

If you have File > Preferences > Check for updates on startup checked, the Arduino IDE may occasionally notify you that a new version of Arduino AVR Boards is available, you'll need to refrain from updating back to the new Arduino AVR Boards version, otherwise you'll be back to seeing the segmentation fault error again.

The error also doesn't occur with the beta version of Arduino's AVR toolchain, so I think the issue will no longer occur in the next release of Arduino AVR Boards.
