If I move the whole project to another computer, without any changes, then the IDE doesn't give out an error message. I deleted the files generated by IDE or compiler in directory "users\appdata\temp\arduino.*" without any effect. I think there should be the possibility to clean the environment.*

have you put variable defiinitions in a header file then included the header file in more than one C or C++ source file ? this can cause multiple definition errors
you should only have declarations in a header file
post your code (using code tags </>)

3

Which version of the IDE?
