Not sure if this belongs here. I have been getting nonsense errors and warnings in my error list in visual studio in my arduino project. Depending on the cpp file I have open, it can be anywhere from 3 errors, to 500 errors. They are pretty much always in the standard libraries, like stdlib.h, wstring.h, etc.

I also get silly errors in my own code, like "too many arguments in function call" on strlen for the following line (as an example):

size_t len = strlen(_rawInstructions[_cursorY]); 

Everything builds just fine, but visual studio is freaking out, and these issues defeat the purpose of using the ide in the first place. Anyone have any ideas?

Ok, I can try my best..

I am running VS 2015 on Windows 8 with the latest version of visual micro. I installed the Intel Curie 32-bit Arduino/Genuino101 package on the board manager, and I have that selected in visual micro. I believe I have arduino 1.8.1 installed. Is that all the info you need, or is there more that I can gather for you?

Hello, I've emailed you with the build output. Thanks for the help!

I found you email, sorry

All the 101 string methods use syntax that visual studio c++ intellisense doesn't like. We will shortly move to using some new visual studio compilers that will cater better for the gcc language.

You will see this if you use the "goto definition" command to drill into the "string.h"

size_t	 _EXFUN(strlen,(const char *)); 

You will find that atmel studio and visual micro work much better in this area, although still not 100% perfect.

There is a workaround for vs which isn't great but works. VS intellisense has its own #define so you can safely redefine methods and get rid of the error reports. It doesn't affect compile so it's flexible.  More info here  

http://www.visualmicro.com/page/Extending-Visual-Studio-Intellisense.aspx

example: redefine strlen

//my_vsintellisense.h

#if _MSC_VER
size_t strlen(const char *);
#endif 

There are some intellisense improvements in the next release

One question: How was _rawInstructions[_cursorY] defined?
