That is what worries me actually. Apparently libc++abi has to be linked
to libc++ but that is not the case with current package:
ldd /usr/lib64/libc++.so
linux-vdso.so.1 (0x00007ffe1c7d8000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f09d5072000)
libc.so.6 => /lib64/libc.so.6 (0x00007f09d4cac000)
libm.so.6 => /lib64/libm.so.6 (0x00007f09d49a3000)
librt.so.1 => /lib64/librt.so.1 (0x00007f09d479b000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f09d4584000)
/lib64/ld-linux-x86-64.so.2 (0x000055b90043d000)
I am not a pro in C++, compilers and linkers so perhaps someone with
more knowledge can explain how this is supposed to work in the first place.
I also cannot find libc++abi or libcxx-abi in the repo unless it is
"cleverly" named as something else.
Perhaps also relavant:

Trying to compile a hello world cpp on Fedora 25 with clang++ and

sudo dnf install clang libcxx-devel
#include <iostream>

int main()

std::string a = "abc";
std::cout << a;
}
clang++ -stdlib=libc++ hello.cpp
This results in a bunch of linker errors. What am I missing?
Tried, got many linker errors. Searched on cxa_end_catch, and found
this page. Might get you closer.

Didn't track down the package for -lc++abi, left as an exercise for the
reader.
