Hi Ismail,

ARM Linux shouldn't use SJLJ exception handling, but again, nor does EHABI
work yet, so you should be ok in disabling EH for now, if that helps you
build the library (I don't know).

Support for EHABI is coming a long way, and I hope we can have something,
even if basic, for the next release. But that doesn't help your problem,
and someone with more knowledge on the libcxx could chime in to help you.
