Hi, 

I'm not sure which forum to post in, so please correct me or move this post to where it needs to be.

I have just upgraded from AS6.2 to AS7, and also upgraded to the latest VisualMicro for Arduino beta (a couple of hours ago).

I can't link my project successfully any more, please can someone advise me of things to try?

My steps so far:
1) before I started, I had AS6.1 and AS6.2 installed, and was using AS6.2 for my Microduino project (using Arduino 1.6.3) - no problems.

2) I downloaded and installed AS 7 this morning.
3) I then downloaded and installed VM4A from http://www.visualmicro.com/page/Arduino-Visual-Studio-Downloads.aspx.  I did experience the "Manifest" problem, but followed the guide to work around it (using my V2014 vsixinstaller)

Now, I get hundreds of errors during creation of the .ELF, indicating duplicate symbols, and it appears for every single source file (.CPP) in the project.

Here are the first few lines:
new.cpp.o:In function `__cxa_pure_virtual'
Adafruit_GPS.cpp.o:In function `Adafruit_GPS::common_init()'
Adafruit_GPS.cpp:common_init()'
Adafruit_GPS.cpp.o:(.bss.recvdflag+0x0): multiple definition of `recvdflag'
Adafruit_GPS.cpp.o:(.bss.recvdflag+0x0): first defined here
Adafruit_GPS.cpp.o:(.bss.lineidx+0x0): multiple definition of `lineidx'
Adafruit_GPS.cpp.o:(.bss.lineidx+0x0): first defined here
Adafruit_GPS.cpp.o:(.bss.line1+0x0): multiple definition of `line1'
Adafruit_GPS.cpp.o:(.bss.line1+0x0): first defined here

Can anyone help me to understand/fix this?

I was able to compile and debug normally before I did the upgrades.

Many thanks
Adrian

Thank you Tim,

I have posted the output as suggested to info[at]visualmicro.com, would you mind having a look at it?

Thanks in advance
Adrian

Ok Tim, I have done that.  The result seems to be identical, still the hundreds of duplicates.   

Is there something else I can try? Perhaps folders to check?

Regards
Adrian

I think this is actually a bug in the Microduino Ide

I see some reports about this and can see they have updated from the arduino 1.6.3 version to 1.6.5-r2 which is more stable

Please try it

Tim, I got it sorted out by creating a new Arduino project IN AS7.  Thank you for the help!

Best regards

I did send it you yesterday, did it not arrive?

You are correct in surmising that the project had some of the sources bound into it. I loaded it into a text editor in an effort to understand why it was trying load sources from my previous version of the arduino (microduino) IDE, even after it had been uninstalled, and I had carefully removed all links in the project options via the UI dialogs.

and I forgot to say that you can switch off these new features by changing the compatibly settings in tools>options>visual micro.

Switch off "Compile Files in Project" which falls back to compiling the sources found in the physical sketch folder regardless of the Visual Studio project structure. This of course is how the Arduino Ide works but can be quite limiting for larger projects.

However, as stated earlier, using the Visual Micro command to see all underlying sources "project>show all core and library sources" is a way to see all the underlying code in the project without confusing the compiler.
