Adding User Library and Arduino Due

I am not able to compile any sketch that uses an external library such as Wire. Not even using the existing examples. I use Visual Studio 2010 - Atmel Studio 6.2, Windows 8.1.

Hi,

I think the first thing to do is to close the Vs intellisense reporting list because it can be confusing. Please see the little X to the right of the "Error List" caption so that the Errors, Warnings and Messages disappears.

You are concerned with compiler errors not intellisense reporting so you do not need that window.

You can then try to compile and upload so that we can see if there is an error and if so what the error is. However the <wire.h> include in your picture does not have a red squiggle below it so it looks like Visual Micro will happily compile okay.

Please click F5 or the blue arrow on the tool bar, then post the compiler/upload output that appears. 

Or please notice the tab at the bottom beside "Error List" called "Output". The build information on the �Output" tab is important and useful.

Thanks

Thanks for the quick response. But what I am trying to really compile is the following code and gave me the same output in IntelliSense. So according to you I shall ignore those.
Now the following '.ino' compiles just fine using the Arduino IDE but using the Atmel Studio + Visual Micro gave me the following :

[code abi-ar" rcs core.a" HID.cpp.o"
ar" rcs core.a" USBCore.cpp.o"
ar" rcs core.a" variant.cpp.o"
g++" -Os -Wl,--gc-sections -mcpu=cortex-m3 r_scripts/gcc/flash.ld" ue_x_dbg/MPU6050_DMP6.map" -o MPU6050_DMP6.elf" g" -lm -lgcc -mthumb -Wl,--cref -Wl,--check-sections -Wl,--gc-sections -Wl,--entry=Reset_Handler -Wl,--unresolved-symbols=report-all -Wl,--warn-common -Wl,--warn-section-align -Wl,--warn-unresolved-symbols -Wl,--start-group syscalls_sam3.c.o" MPU6050_DMP6.cpp.o" I2Cdev\I2Cdev.cpp.o" Wire\Wire.cpp.o" MPU6050\MPU6050.cpp.o" sam3x8e_gcc_rel.a" core.a" -Wl,--end-group

Binary sketch size: 40,656 bytes (used 8% of a 524,288 byte maximum) (10.47 secs) [/code]

I never saw it generating the '.hex', only these '.o', '.elf', '.map', '.bin'

The other error that I am having is; lets say I want to put the default '..DMP6.ino' example into a separate class (.h and .cpp) and use a default (main) '.ino' to call the update routines. Then Atmel get confuse because cannot find the headers files?!

Thanks for the info. Yes the error list does often include compiler output a whole load of other stuff that can be ignored which is why I said it caused confusion. 

Further more your report and screen shot do not give much detail but the compiler output you have posted shows the specific errors, which user libraries and where they are located. The direct error resulting in failed compile as� "redefinition" error. 

Once a compile has failed other errors will appear because of the missing compiled files. It isn't possible or easy to distinguish the main cause of the errors from the "Error List", especially from a screen grab. 

Therefore, providing support using the output is much easier.

Please switch on "tools>options>visual micro>compiler>verbose" then run the build. 

Email the resulting output to info[at]visualmicro.com. 

This will save me asking a bunch of questions. 

I suspect it's a path config issue/bug that we can workaround but just in case and to save time please also zip your sketch and email it. I can also look at your second report above which suggests some confusion somewhere. Header includes are very standard so should work.

forgot to say. before emailing the verbose output click "Build>Clean Solution" then click build. This will give a full output from a clean compile, thanks

Got the email thanks. I'll take look at the 6050 compile issue asap

Some immediate pointers

1) In the Visual Micro Ide config manager it is the folder name where the arduino.exe exists and NOT the name of the exe that is required however I think visual micro auto truncates?

2) The arduino rules are that non library #includes must reside in the same folder as the sketch. We adhere to this rule to avoid support issues. Your IMU project does not have an imu.h in the folder so the #include will fail.

3) With a project open, please confirm if the libraries show on the "Project>Add/Import sketch library>core" menu

Thanks

1. Checked that is = to C:\arduino-1.5.6-r2-windows\
2. Maybe I am confuse. But if I add the directory to the list it shall try to look for those libraries?
3. I noticed that if the external class (not the .ino) is the one that calls the library is then when, the application cannot find it. But if I add the library to the .ino it finds it. Is that how suppose to work?

Yes that all looks good. Yes it is an Arduino rule that libraries must be included into the main sketch.ino. Library includes in .cpp files will only be discovered that way,

Can I assume that when you tested in the arduino ide you had the correct source code but when you tested in visual micro it was changed slightly? This would explain why it worked in arduino and not in vm?

But for me that does not make sense at all. Because then why the Arduino has a folder called Libraries? We supoose to put external libraries to avoid adding it to every arduino sketch.

So I did it anyway. Now I have to add every arduino core library to where the sketch is located?

See below

Hi

Good news. I finally got it working in Visual Micro. I got it as I was thinking of how is suppose to work, without adding any library to where the .ino is located. Compiles in Arduino IDE and Visual Micro. However, I still do not have the *.hex.
How can I do to get it?

[code eabi-ar" rcs "C:\Users\Me\AppData\Local\VMicro\Arduino\Builds\IMU\arduino_due_x_dbg/core.a" pp.o"
-ar" rcs "C:\Users\Me\AppData\Local\VMicro\Arduino\Builds\IMU\arduino_due_x_dbg/core.a" pp.o"

Hi,

I said include your libraries in your main sketch.ino not copy them anywhere different. I also explained the reason you NEED to include in the sketch.ino is because you were trying to use the libs from cpp/.c files and having a problem.

#include "mylib1.h"
#include "mylib2.h"

If you are new to arduino I suggest you add your libraries using the menu called Project>add sketch library" then you will see the #includes

It would also save us all some time if you used the documentation from visualmicro.com Smiley http://www.visualmicro.com/page/User-Guide.aspx?doc=Add-Libraries.html

As concerns library locations there are two. One below the Arduino Ide folder that you have used and one below the SketchBook folder normally mydocuments\arduino\libraries. The latter are called user libraries and will remain if you move your arduino ide location.

You will also find in the documentation that you can switch on "tools>options>compiler>show builder folder" which provides a hyperlink to the build files (elf,hex) in the compiler output

All of this, except showing the build folder is standard arduino and is covered in the arduino.cc documentation.

Thanks
