that is defenitely a Windows 7 64bit thing, same exact setup works fine under 32bit. I guess it has to do with the path. Under 64bit one must copy the libraries under \hardware\msp430 folder to work but under 32bit it works fine if the libraries are located in their normal location in the sketch directory 

after fighting with the terrible string handling of msp430-g++ I finally got ESP8266 to work with MSP430 G2553 and upload telemetry data to ubidots. This is a REAL working code, no BS. Thanks to all who suggested using standard c str instead of the "String" object.
