I am testing the sample code.
But it is quite troublesome to have the -Werror option for compilation.
Any idea to remove this option in Developer studio?

mkapp builder indeed turns on -Werror option by default.
You can negate this option for some (or all) warnings by adding a -Wno-error=all option.
(You can add it to mkapp command line in Project Properties > C/C++ Build > Settings)
Thx for your reply, but it is not working for me…
I put the “-Wno-error=all” in Project Properties > C/C++ Build > Settings-> mkapp Tool -> C build option -> Additional compiler option
Any idea?

Hum, sounds like using “all” keyword isn’t doing anything here…
Alternatively, you can specify warning types one by one (e.g. in your case: -Wno-error=unused-variable)
