I was trying to compile the code from "The improved interface of the associative containers" from Rainer Grimm's blog but it choked on std::map::insert_or_assign. Of course on Windows with clang you have to use the GCC headers
The problem is that it comes up with a strange error in the the GCC headers

I failed to find system interal header files (like <iostream>).
I can pass arguments to compile every time, but is there a way to change the default includes?

just want to change these default nonexistent directory (I built clang from source)
The trick I use with GCC, which should also work with Clang, is using the environment variables C_INCLUDE_PATH/CPLUS_INCLUDE_PATH for compiler include paths and LIBRARY_PATH for linker library paths.
I am trying to use clang-11 to cross compile a c++ file to aarch-linux-gnu, from my host machine which is x86-64.
Here's the command :
clang-11 -v -target aarch64-linux-gnu -B/usr/aarch64-linux-gnu/lib -march=armv8.5-a+memtag -fsanitize=memtag test_mte.cpp -static
But, I run into this error:
In file included from /usr/bin/../lib/gcc-cross/aarch64-linux-gnu/8/../../../../include/c++/8/stdlib.h:36: /usr/bin/../lib/gcc-cross/aarch64-linux-gnu/8/../../../../include/c++/8/cstdlib:41:10: fatal error: 'bits/c++config.h' file not found #include <bits/c++config.h>
I have installed the packages gcc-multilib g++-multilib binutils-aarch64-linux-gnu libc6-arm64-cross libc6-dev-arm64-cross crossbuild-essential-arm64 gcc-aarch64-linux-gnu
How can I resolve this error?

It seems to me that clang is asking some gcc about system include paths, and this process fails (for some reason), leading to inclusion of host headers.
Here is a solution that helped me:
https://askubuntu.com/questions/947954/wrong-default-include-directories-for-clang-cross-compile
Basically you provide all system includes on your own. In our case (arm64), for me this boiled down to these flags:
-nostdinc++
-cxx-isystem /usr/aarch64-linux-gnu/include/c++/10/`
-cxx-isystem /usr/aarch64-linux-gnu/include/c++/10/aarch64-linux-gnu/
-isystem /usr/aarch64-linux-gnu/include
So I just upgraded to clang 12 because I need <compare>, and as soon as I try to recompile I'm hit with
./test/math/ordering.cpp:6:10: fatal error: 'compare' file not found
#include <compare>
^~~~~~~~~
1 error generated.
I checked and (according to cppreference and the official gnu site) my version of libstdc++6, 10.3, is supposed to include this header. I'm compiling with this command:
clang++-12 ./test/math/ordering.cpp -o ./test/math/ordering.exe -I ./inc/lcu --include testing/assert.h -std=c++20 -stdlib=libstdc++
Running it with -v prints:

I ran apt update and apt upgrade, but everything was already up to date. Any ideas?
I use CMake 3.18 with CLion 2020.2.5 and want to use Clang as CUDA compiler. I do with this with the following two lines at the top of my CMakeLists.txt:
set(CMAKE_CUDA_COMPILER_ID Clang)
set(CMAKE_CUDA_COMPILER ${CMAKE_CXX_COMPILER})
And it works very well for the code, and I also CLion seems to be able to work with the code just fine. But it still complains while configuring the project:
-- Configuring done
-- Generating done
-- Build files have been written to: /home/mu/project
Problems were encountered while collecting compiler information:
Unexpected compiler output. This compiler might be unsupported.
If you are using GCC/Clang, please report the bug in https://youtrack.jetbrains.com/issues/CPP.

Compilation of the CUDA compiler identification source "CMakeCUDACompilerId.cu" produced "a.out"
The CUDA compiler identification is Clang, found in "/home/mu/project/CMakeFiles/3.18.4/CompilerIdCUDA/a.out"
How can I resolve with issue between CMake and CLion?
I want to do cross-compilation of following source file (Foo.cpp)
#include <cstdint>
int Foo()
{
uint32_t bar = 0;
return bar;
}
with i686-w64-mingw32 and arm-none-eabi on a Windows 10 system. Therefore I use following batch file
#echo off
set "PATH=C:/MinGW/i686-8.1.0-release-win32-dwarf-rt_v6-rev0/bin;%PATH%"
set "PATH=C:/GNU-Tools-ARM-Embedded/7-2018-q2-update/bin;%PATH%"
set "PATH=C:/LLVM/7.0.0/bin;%PATH%"

So for the i686-w64-mingw32 it's enough to put the location of the compiler to the path, but for arm-none-eabi the clang compiler can't find the cross-compilation headers.
Does somebody know how to configure clang for arm-none-eabi?
Why does this following happen?
Target: arm-none--eabi
Shouldn't it be?
Target: arm-none-eabi
Thanks!

I'm a bit late to the party but here are my two cents anyway:
The --sysroot option should be:
--sysroot=C:/GNU-Tools-ARM-Embedded/7-2018-q2-update/arm-none-eabi
You are missing the /arm-none-eabi part at the end. Clang looks for the directories bin, lib and include which are in the arm-none-eabi subdirectory of the toolchain (see the documentation here).
This should fix the "ignoring nonexistent directory" errors and the fatal error because of the missing standard library.
