Thanks for the zip. Sorry no idea what the problem is. As you say it's a very simple project and there are plenty of people compiling that without issue.

Maybe try restarting Visual studio or the pc.

Failing that delete the visual micro registry key HKEY_CurrentUser\Software\Visual micro.

Then restart vs and re-enter your ide location but do not change any other settings.

Thanks


Here is result of registry cleaning

In error window written (translation) "...Unknown error (Exception from HRESULT..."

Thanks.

The error dialog is related to intellisense however it suggests that you are not using a standard Visual Studio project or that the project has been switched from win32/app/dll to a make project.

I suggest you create a new project as a test using "File>New>Arduino Project". Then build and confirm the empty project compiles okay. Then click "add>arduino library" and check it compiles okay?

If that works I will tell you what the problem was with the current test project.

Thanks

* I have created totally new Adruino project.
* I did not created any local libraries

And, as I mentioned in first post, results:

1. If I switch option "Compile Files In Project" to "True" I get:
Code
Select All
Compiling 'TestLocalLibrary' for 'Arduino/Genuino Mega w/ ATmega2560 (Mega 2560)'
core.a(main.cpp.o)*:In function `main
main.cpp:undefined reference to `setup
main.cpp:undefined reference to `loop
collect2.exe*:error: ld returned 1 exit status
Error creating .elf


2. If I switch option "Compile Files In Project" to "False" project compiles well:
Code
Select All
Compiling 'TestLocalLibrary' for 'Arduino/Genuino Mega w/ ATmega2560 (Mega 2560)'
Binary sketch size: 642 bytes (used 0% of a 253 952 byte maximum) (0,19 secs)
Minimum Memory Usage: 9 bytes (0% of a 8192 byte maximum)

Another experiment:

0. Got new, fresh PC
1. Installed VS2015 Enterprise
2. Installed VMicro
3. Downloaded and unzipped Arduino 1.6.6
4. Run once arduino.exe then closed
5. Run VS, specified Arduino IDE path 
6. Created new Arduino project
7. Build it and got same error:

Code
Select All
Compiling debug version of 'TestCompile' for 'Arduino/Genuino Mega w/ ATmega2560 (Mega 2560)'
core.a(main.cpp.o)*:In function `main
main.cpp:undefined reference to `setup
main.cpp:undefined reference to `loop
collect2.exe*:error: ld returned 1 exit status
Error creating .elf


Notice: nothing was changed in any settings, it was first VS2015 and VMicro installation on that PC

Finally! I found out what is the problem:
If any part of path to sketch location contains leading point "." build will fail with error:

Code
Select All
core.a(main.cpp.o)*:In function `main
main.cpp:undefined reference to `setup
main.cpp:undefined reference to `loop
collect2.exe*:error: ld returned 1 exit status
Error creating .elf


And we use such pathes now like ".Sketches"/".Projects" etc

Yes I just found an article on google about this issue also with the arduino ide (but maybe fixed more recently)

But I didn't see a . or other illegal characters in the output you posted. No .Sketches"/".Projects etc.

Which operating system are you using?
Which path contained the "."?

Thanks

I use Windows 10 and Linux based PCs, by fact - point by itself is not illegal character, in linux it "hides" folder, e.g. in ftp

In my output, when I have changed real pathes due to privacy I've made mistake and replaced leading dot too.. 
So it is my fault with logs. Real path contains dot in "Projects" => ".Projects"

Okay thanks very much for all the info.

I will try to replicate and change if possible.

Pleased it's working now. 

Hopefully local libraries etc all work without any change of settings?

Just tested local libraries - works perfect Smiley

Thank you for your time!

It would be nice if you could fix "dot issue", ofcourse in case it is VisualMicro related.

Will try but it might be a gcc issue. Did it cause a problem in the arduino ide?

1. It compiles well in Arduino IDE
2. It compiles well in VMicro with option "Compile Files In Project" set to "false"
3. It fails to build in VMicro with option "Compile Files In Project" set to "true"

So, I assume it is VMicro related

Excellent thanks. 

There is a difference between compiling files in the sketch folder and compiling only the files "included" in the VS project. This is what the compatibility settings control.

I expect a Visual Micro bug when excluding files that are supposed to be hidden source control files (which normally start with a "."). 

Thanks again for the useful diagnostic work!
