command_center.ino fails to compile

[chriskm]

When I try to compile command_center.ino, it fails to compile and outputs following error message:

Please update your AzureIoT library.

1. Delete the old AzureIoTHub from Arduino/libraries directory
2. Install the new AzureIoTHub, AzureIoTUtility, and AzureIoTProtocol_MQTT, all on version 1.0.17
3. Update all other libraries, including the esp8266 by ESP8266 Community in the 'Boards Manager' that must be version 2.3.0

Localize the target directory, Were Arduino IDE is placing the ino.elf file, it is probably in the C:\Users\\AppData\Local\Temp, you should have a directory called arduinobuild or only build_... Once you localize it, delete all files inside of this directory.

Build again your ino file.

OK, thanks for your reply, it helps and now it works for me on Win10. However, on macOS Sierra it still fails on this:

The same problem is in the simlpesample_http example:

@jirkakoutny In case you didn't figure it out, it's because he's using backslashes in his absolute paths. Can hardly blame an MS employee for being Windows-centric. Edit the library files in question and replace the offending character with a proper slash. Done and done.

@NoahNOA THX! I did not notice it myself, thanks again.
