Compiler Options for Teensy 3.1

Print Post  
I am using AtmelStudio 6.2.1548+SP2 and I already installed the Teensyduino and VisualMicro in that environment .
I am wondering how can I change the compiler settings for arm gcc that is used for Teensy (Which menu options) I want to activate C++11 features in this environment.

Hi,

I am not sure exactly what you need to add but if just a simple compiler switch then you can try to add it to the "Extra Flags" in the Project (Global) section of the project properties.

Extra Flags - Project
Extra Flags - Configuration

To view the properties select the project node in the solution explorer and press "Alt+Enter" or "View>Properties Window". The properties should display as a tool window.

No,
This does not work even the project settings are related o AVR8 I think none of the settings from AtmelStudio affect the Teensy board selection settings.
I think it takes the settings saved and taken from a TeensyDuino setting file that I do not know its name but I am not sure how visual micro override some settings to the compiler like CPUFreq,....

Hi,

If you are using a recent version of Visual Micro this property should be passed to the compiler. It will not affect the Ide but the first task musty be to affect the compile.

Arduino/Teensy build defs normally allow for the extra flags param and this is how Visual Micro manages to pass the flags to the compiler.

Please set "Extra Flags - Project" and also turn on "tools>visual micro>versbose". Then build and post the compiler output for one file.

Thanks

Hi,
Thanks for your reply.
I retried again and I filled the Extra Flags - Project with wrong switch 
In fact it should not compile, but this switch did not reflect into compiler parameters.
Please check the screenshot and the enclosed build output(verbose).
