	I'm having problems compiling/linking a piece of code using visual micro for Aduino. I've narrowed it down to the ArduinoJSON library. I installed the json library as I've installed other libraries, by downloading the ZIP file and then installing the library as a zip. Once I do that the library, its examples etc are available. I then open the JsonParserExample, and compile it under the arduino 1.6.5 GUI, and it compiles/links fine. When I load the exact .ino file into VS pro 2015, running Arduino for Visual Studio 1.0, I get the following errors: JsonParserExample.ino:In function `setup JsonParserExample.ino:parseObject(char, unsigned char) JsonParserExample.ino:In function `get<char const> JsonObject.ipp:JsonObjectKey) const JsonObject.ipp:as<char const>() const JsonParserExample.ino:In function `get<long int> JsonObject.ipp:JsonObjectKey) const JsonParserExample.ino:In function `as<long int> JsonVariant.ipp:asInteger() const JsonParserExample.ino:In function `get<ArduinoJson::JsonArray&> JsonObject.ipp:JsonObjectKey) const JsonObject.ipp:_invalid JsonObject.ipp:_invalid JsonParserExample.ino:In function `get<double> JsonArray.ipp:getNodeAt(unsigned int) const JsonParserExample.ino:In function `as<double> JsonVariant.ipp:asFloat() const JsonParserExample.ino:In function `get<ArduinoJson::JsonArray&> JsonObject.ipp:JsonObjectKey) const JsonObject.ipp:_invalid JsonObject.ipp:_invalid JsonParserExample.ino:In function `get<double> JsonArray.ipp:getNodeAt(unsigned int) const JsonParserExample.ino:In function `as<double> JsonVariant.ipp:asFloat() const collect2.exe:error: ld returned 1 exit status Error creating .elf In comparing the verbose output from the arduino build against the vs2015/vm build, the main difference is that the VM build is not building the json library, and hence its not linking to the json library. This is the first issue I've had with the Visual Micro plugin. I am continuing to program with the Arduino GUI, but its just not as nice. I'd appreciate any help or insights anyone might be able to give me ...

	Thanks for the good info. It's fixed in next release but this one made me laugh note: See the workaround at the end of this post for a quick fix. May 2015 Visual Micro was patched because the ArduinoJson library was a version 1.0 library but contained arduino version 2.0 library format structure which it required the Ide to ignore. Now the ArduinoJson library is version 2.0 format but contains a version 1.0 format file that it requires the Ide to ignore. I have removed the patch from Visual Micro which means the Visual Micro code is clean again. Great! What visual micro now does is detect the "\src" folder in "C:\Users\David\Documents\Arduino\libraries\ArduinoJson-master\src" to determine a version 2.0 library The older patch that you have, instead looks for a ".h" file in "C:\Users\David\Documents\Arduino\libraries\ArduinoJson-master" to determine version 1.0 and not 2.0 library. and guess what! There is a "C:\Users\David\Documents\Arduino\libraries\ArduinoJson-master\ArduinoJson.h" that does not do anything, is not used and should not be there. Workaround 1. Rename "C:\Users\David\Documents\Arduino\libraries\ArduinoJson-master\ArduinoJson.h" to "ArduinoJson.x" or delete it. 2. Click "tools>visual micro>reload tool chains" or restart the ide.

	Workaround worked like a charm! Thanks for the explanation as well. Cheers.
