Compile error. Version 0.5.3

[Omnn82]

Can you tell me what causes the following error when compiling the firmware (version 0.5.3)? On version 0.5.2 there is no such problem.

collect2.exe: error: ld returned 1 exit status

I'm facing exactly same problem, with the same result...

[vitotai]

I couldn't reproduce.
It seems like a compiler relate issue. There is no '_Z13commitSettingv' function but 'commitSetting'. The compiler seems to generates another symbol for some reasons.

On version 0.5.2 there is no such problem...
Visual Studio version - 1.87.1

[vitotai]

my bad. One file was missed.

[dmcaetano1]

Now, everything is fine here. Thanks Vitotai!
