I've been trying to use clang with libc++ in an Eclipse CDT project, but every time I add "c++" and delete "stdc++" in
Project->Properties->C/C++ Build->Settings->Tool Settings->LLVM Clang C++ Linker->Libraries
"stdc++" gets re-inserted, and both libraries get linked.
Using the flag "-stdlib=libc++" still ends up with Eclipse linking to "stdc++".
How do I get Eclipse to use only libc++?

I've found a solution, which in retrospect seems so very, very obvious.
When creating a project and choosing LLVM/clang as the toolchain, I went to the compiler settings Project -> Properties -> C/C++ Build -> Settings -> LLVM Clang++
and appended
to the "Command" field.
I also added "c++" to be included by the linker:
Project -> Properties -> C/C++ Build -> Settings -> LLVM Clang C++ Linker -> Libraries (-l)
The presence of the "stdc++" library can be safely ignored.
To test if "libc++" is really used, I've written the following piece of code:
#include <iostream>
int main() {
std::cout << _LIBCPP_VERSION << std::endl;
return 0;
}
In my case, the output was
which corresponds to clang 7.0 on my system.
Edit:
Update: I mistakenly typed "-std" instead of "-stdlib".
