error: expected '{' before '::' token

Hi @luni64,

I'm having the following error when compiling with arduino-cli:

Error during build: exit status 1

Nested namespace definitions require C++17; I think it's a bit too early for that.

Dear @luni64

Same issue here!

The code used to work fine some months ago. Now, my project is broken and won't compile:

as @bblanchon mentioned is this related to C++17 features?

[dzalf]

Guy, I think I spoke too fast. 😞

I was using an old version of the library. After updating it to 1.4.1 in my platformio project, the code compiles fine

luni64/TeensyTimerTool@^1.4.1 yields:

luni64 is right might be broke: none of the github examples compile: all give this same error.
TeensyTimerTool\src\TimerModules/RTC/RTC.h:5:26: error: expected '{' before '::' token
namespace TeensyTimerTool::RTC_t

[us866]

tried 1.4.1 and 1.4.0 library
