Cygwin errors ? how to remove

Hi all, new user here.
When I compile (VS8) Sept 14 VMicro) 
I get LOTS of - for example
  Preferred POSIX equivalent ms_T31.elf
:CYGWIN environment variable option "nodosfilewarning" turns off this warning.

It compiles ok - I know nothing of Cygwin ?
I have added Cygwin and the nodosfilewarning to the system environment variables and rebooted - exactly the same.

Also - with intellisense - I seem to get lots more than Arduino  !! - how can I limit it to just arduino commands please ?
Many thanks
And hi to all.
Joe

Hi Joe,

Arduino 1.5.7+ uses cygwin and Visual Micro sets an Environment variable to prevent the warning you are seeing.

It's strange that you see the warning. Can you please confirm the version of Visual Micro you are using from tools>options>visual micro>version>version?

If you are using the latest release 1407.10 of Visual Micro we will have to look into why the env var is not working on your pc. Maybe you already have another piece of software that has set this variable. Please look in "computer>advanced>environment variables" and look for the CYGWIN variable. 

If it doesn't exist then add it with a value of:-

Code
Select All
nodosfilewarning


Look forward to hearing your vm version and if the variable exists in your global pc config aready.

Let's deal with intellisense discussion in another thread to keep things clean. When you create the thread please confirm the hardware and arduino version you are using.

Thanks

EDIT: Another thought. Arduino 1.0.6 was released a few days ago. I haven't had an issue with it but if you are using 1.0.6 then let me know that would change my answer. Thanks

Hi Tim,
VM 1.1407.10

Arduino 1.57

VS 2008

Win 8.1

Sorry if you missed it but as I said in my post, I added the global environment variable prior to posting, no difference at all.
Out of interest - I was trying to run with 1.06 arduino prior to this and there were no boards or programmers - com ports yes - but boards and programmers blank - on both VS and Atmel 6.2
Using the beta of Arduino solved the boards and programmers option but then got the cygwin -  note - there are no problem at all in Atmel 6.2 with cygwin.
Joe

Hi Joe,

Sorry I missed the version info.

1)

I have replicated the cygwin warnings issue with Visual Studio 2008. Will have to look into why this happens for 2008 and not for all other VS and Atmel versions. I suspect that it is something to do with .NET3.5 which the 2008 version of Visual Micro has to use. All other versions of Visual Micro use .net 4.0 or 4.5. Each Ide loads the version of Visual Micro that it requires.

2)

The boards will be blank if you attempt to configure 1.0.6 location for the Arduino 1.5.x setting. You should select the Arduino 1.0.x location setting for 1.0.6.

You can run Visual Micro with both 1.0.x and 1.5.x locations configured then use the tool bar to switch between them for individual projects or tests.

I'll post again when I find why vs 2008 is ignoring the CYGWIN=nodosfilewarnings environment variable. Your guess will be as good as mine!

Many thanks Tim,
The boards were blank with V1.0 selected also - on both Atmel 6.2 and VS.
Loading 1.57 and setting 1.5 cured that. I could not run V1.0 with the release arduino at all.

Hi Joe,

Did you install 1.0.6 into the same folder that previously contain 1.5.7 or a clean new folder?

This info will help me track down what happened to you.

Thanks

Hi Tim,
I originally had 1.06, so tried with - nothing on either atmel or VS with 1.0 set (no boards or programmers - but comm ports ok)
I then uninstalled and cleaned the old arduino (program files x86) - then reinstalled into c:\arduino - no difference.
Then replaced it with 1.57 (after full deletion of 1.06 and folder) - works but cygwin errors as you know - atmel ok.
Couldnt get 1.06 working any way at all.
Joe

Hi,

So with 1.0.6 and 1.5.7 installed you had both Arduino 1.0.x and Arduino 1.5.x as options in the tool bar?

When you selected Arduino 1.0.x the tool bar boards list became empty and when you selected Arduino 1.5.x the "Yun" appeared?

Thanks

ps: did you re-start your pc after setting the CYGWIN environment variables. I found a blog on google that suggested this might be required for .net3.5. Might be a red herring

Hi Tim, yes restarted after system variable - no difference - 
I have never tried the 2 arduinos together.
I can test if you like ? 
Please advise how to run both together ?

Just to clarify, it was 1.05 r2 I was using - I cannot dl 1.06 at the moment as their server appears down.

Ok ,
Have installed 1.06 AND 1.5.7 - pointed the ide location for each at the appropriate folders -

Cannot see boards with 1.06 - ok with 1.57


Cygwin still same.

Hi Joe,

Let's open a new thread for your boards issue because I know that there are over a 100,000 users who can see the boards so need to ask you some questions. When you create the thread please include a screen shot of the ide locations dialog with the path configured for 1.0.x

The CYGWIN warnings will be fixed by scouting the internet for an understanding of why a .net3.5 app would ignore environment variables. In the meantime I recommend atmel studio instead of Visual Studio 2008

Thanks

Out of interest - how many of those users are using VS 2008 and win 8.1 ?

Well the windows version doesn't make any difference but 2008 + Arduino 1.0.x is a combination that dates back to the beginnings of Visual Micro and the code is built from the same code base just compiled for each .net platform.

So it really is a lot of users and many years of testing for the combination you are using.

The Arduino 1.5.7 beta with the CYGWIN errors is a new combination but that is not 1.0.x.

I think when we look at some trace and config options that I will tell you about we will see the reason. The screen shot of the Ide config window with the path might also show something up.

But hopefully in a different thread so that other users can search and find the same discussion if applicable.

By the way did you run arduino 1.0.x to test it installed okay?

Thanks
