Hi Val,

The solution is described above but you can also download the latest BETA from our download page on visualmicro.com.

The cause is that the toolchain in 1.5.8 does not auto discover files that it requires which are installed into the arduino ide folder when you install the arduino ide. The files are cygwin files.

The atmel gallery version of visual micro resolves this for most users but if you have installed any software (such as winavr) that includes cygwin that has also added its location to your windows path then arduino 1.5.8 still becomes confused. 

The latest beta simply ensures that the arduino ide folder has priority over all other path definitions (only applies when the toolchain is running does not globally affect your pc config)

The beta is SP4 of the version you are running so it is quite mature.

Thanks

Oh, maybe it wasn't the issue that I suspected.

Please switch on tools>visual micro>verbose messages and then click build>clean, then build and email the output to info[at]visualmicro.com

That should save me asking a load of questions.

Thanks

as a precaution to avoid wasting your time I also suggest you manually add the location of the arduino ide folder to the start of the "path" environment variable via control panel. Does that make sense or should I explain more?
