@Viste it's not fixed yet so why closing?

[Viste]

is not relevant for me.

[mishaparem]

@FrancescoBorzi I'm still working on this.. slowly, when time permits. Not sure it's specifically related to Clang10, seems more like a bunch of C++11 stuff so far.

[Viste]

@mishaparem just remove from cmake -DCMAKE_C_FLAGS="-Werror" -DCMAKE_CXX_FLAGS="-Werror" because its just warnings in fact and this flags make them errors
and apply

[mishaparem]

@Viste some of the "just warnings" point to potential bugs

[Viste]

@mishaparem this shit works ok for few years with this potential bugs

[mishaparem]

@Viste umm, not sure why that's an argument to ignore potential bugs

[FrancescoBorzi]

@mishaparem I agree that warnings should be fixed, can you please report them in a new issue?

thanks
