C+11 doesn't seem to work well with VM or I missed setting some option somewhere.

In the Arduino IDE I went to platform.txt and added -std=gnu++11 to compiler.cpp.flags

Now it recognizes this:

This option appears to be read by Visual Micro too because I don't need to add it seperately in the command line options. VM behaves weirdly though.

Although it appears to compile, the constexpr keyword is marked as red with "error: this expression has no storage or class type specifier"

Something similar happens with ranges (similar to for each in other languages):

This gives "error: references variable 'x' requires an initializer" in the editor, but again it compilers and it works correctly.

On the other hand, other features work fine. For example the nullptr constant or the auto keyword. That's all I tried though.

Do I need to set some switch in VM too or is this something that's just not supported right now?

Yeah, I already noticed that Intellisense produces some other errors. It doesn't like the pgm_read_word() macro for example.

After doing some research, I guess I should have known this wouldn't work perfectly:

constexpr isn't even supported in VS2013 The range-based for loop on the other hand is supported in VS2012 but not in 2010.

VS2010 supports far less and I will get Intellisense errors on everything that VS doesn't know. And avr gcc now knows more C++11 than VS2010.


I'd like to avoid Atmel Studio though because I already use Visual Studio for C# and Visual C++. So having everything in one program is perfect.
Ah well, they're mostly nice-to-have instead of must-have features anyways.

That said, the stuff works. The fake errors are just confusing.
