Difference Between Compil on Windows or Linux

Using Arduino Programming Questions

Hi everyone,

I'm playing with SHT21 sensors and a library found on Github (https://github.com/misenso/SHT2x-Arduino-Library),
and I found a strange issue. It works pretty well if I try it on windows 7 pro 64bit and then if boot and try it on linux (ubuntu 12.04 64bit), it compile, upload but results are odd:

Humidity(%RH): -5.82 Temperature(C): -46.84
Humidity(%RH): -5.79 Temperature(C): -46.85
Humidity(%RH): -5.79 Temperature(C): -46.85
Humidity(%RH): -5.79 Temperature(C): -46.17
Humidity(%RH): -5.82 Temperature(C): -46.17
Humidity(%RH): -5.82 Temperature(C): -46.17

I'm trying to understand why by looking the source code of library but need some clue... (endian issue?)

So what difference(s) between compil on ubuntu and linux?

if boot and try it on linux (ubuntu 12.04 64bit), it compile, upload but results are odd:

Are you using the Ubuntu repository version? I had some issues with that version. I use Ubuntu 12.04 32 bit and the IDE v1.0.1 downloaded from the Arduino site. Unpack it into a local directory. Run the arduino shell script in that directory to run the arduino site version.

Well done,
Thx a lot
