Compilation error, arm-none-eabi-gcc...

I get the following compilation error for the Teensy 3.1 in Atmel Studio:
Its a sketch that compiles well in Arduino itself.

C:\Arduino\hardware\tools\arm\bin\arm-none-eabi-gcc -c -g -assembler-with-cpp -mcpu=cortex-m4 -DUSB_VID=null -DUSB_PID=null -DARDUINO=106 -I"C:\Arduino\hardware\teensy\cores\teensy3" "C:\Arduino\hardware\teensy\cores\teensy3\memcpy-armv7m.S" -o mcpy-armv7m.S.o"  -mthumb -nostdlib -D__MK20DX256__ -DTEENSYDUINO=121  -DF_CPU=96000000 -DUSB_SERIAL_HID -DLAYOUT_US_ENGLISH
arm-none-eabi-gcc*:error: unrecognized command line option '-assembler-with-cpp'
Error compiling core


Any ideas what causes this?  Undecided

Thanks in advance.

Hi Ralph,

I thought that the -assembler-with-cpp changed for the new Teensy 121 release a few weeks ago.

There was a beta with this change but a new beta was published yesterday. Cam you please give it a try and let me know the result.

Thanks very much

I couldn't find that beta version.
But i tried the 1.22 istead of the 1.21 with the same error.  Undecided

I installed eclipse with the "Arduino Eclipse IDE and Plugin". 
There the sketch compiles too.
It doesn't in the Atmel Studio only.
Are there maybe some more settings to be adjusted in Atmel Studio or Visual Micro?

Hi,

Sorry for the confusion.

You need the beta of Visual Micro from our downloads page not a different version of Teensy Smiley

The changes for Teensy were made on the 20th of March. You are using the March 18th version of Visual Micro so has no support for Teensy 121+

Cheesy Cheesy Cheesy It is compiling and uploading now!

Finally in short for the Teensy 3.1:
I have Arduiono 1.0.6, Teensyduino 1.2.1, the Atmel Studio 6.2 and the Visual Micro beta from yesterday installed.
Then apply the settings from here,
http://www.visualmicro.com/page/User-Guide.aspx?doc=First-steps.html
and here
http://www.visualmicro.com/page/Teensy-for-Microsoft-Visual-Studio.aspx

In the IDE location settings in visual micro for "Teensy 1.0" the path to the arduiono IDE has to be set.
For Example C:\Arduino\

I must say that this installation procedure is quite tought beans for a beginner. Tombraider is easier.  Huh

Thanks a lot for the support.

Best regards Ralph.

Great

So there are two steps

1) Enter the path to the ide in the Ide locations window
2) Enter the three options you want to use for Teensy such as cpu speed, keyboard and usb type.

No 2. relates purely to Teensy, which is more flexible than Arduino. Also the settings in 2) can be changed per project.

So, other than providing some simple menu choices to replace 2) what could be made easier?

Thanks

ps: In Eclipse how did you specify the options for 2)?

If one does this the first time it might be completely confusing, when it doesn't work at all and gives cryptical notifications.
Further more there is this puzzle with the various excluding versions.
But i know better now for the next time.  Smiley

I wasn't requested for any special settings in Eclipse concerning the teensy 3.1. 
Maybe it took the settings from the sketch i started with in arduino first.
I didn't care about this topic, because i prefer the atmel studio, because it's similar to the Visual studio.
I will deinstall that.

I found this video very helpful for a decision.

Okay thanks again for all the info.

I think the main issue is that you came to this when all the Ide's have just changed (last month or so) after being stable for a few years. That's why you got caught between versions. Unfortunately companies like Teensy and Arduino have started to beta for about 24 hours then push the changes. 

It's good in some ways because things move faster but if you are using any software with Visual Micro that has recently been released and not working then it's always worth checking the latest beta.

Thanks again, great to hear you persisted.

ps: Sounds like Eclipse has hard coded some defaults for Teensy maybe we should do the same. Would be interesting to know how you change them when next passing by Eclipse (different cpu speed or usb config). Thanks Smiley

I was getting the same 

arm-none-eabi-gcc*:error: unrecognized command line option '-assembler-with-cpp'
Error compiling core

error using teesnyduino 1.22 and the current stable Visual Micro version. When I installed the beta version of Visual Micro, the error went away.
