I try to utilize Clang AddressSanitizer in NixOS and I meet the following error.

clang-14: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.
make: *** [Makefile:13: build] Error 1
To reproduces the error, I use the following codes.
$ tree .
├── CMakeLists.txt
├── Makefile
├── src
│ └── main.cpp
└── toolchain.nix
$ cat toolchain.nix
with import <nixpkgs> {};
(mkShell.override { stdenv = llvmPackages_14.stdenv; }) {
name = "app";
buildInputs = with pkgs; [
gdb
cmake
ninja
];
}
$ cat CMakeLists.txt

set(project_name "app")

set(CMAKE_CXX_STANDARD_REQUIRED ON)

target_link_libraries(${project_name}.out)
$ make build; cd build; cmake -DCMAKE_C_COMPILER="clang" -DCMAKE_CXX_COMPILER="clang++" -GNinja ..; ninja;
$ cat src/main.cpp
int main(void) {
int* a = (int*)malloc(sizeof(int) * 100);
return 0;
}
$ nix-shell toolchain.nix
[nix-shell] $ make default
Finally, the system will occurs the same error.
I guess it seems the system use the GNU Binutils by default and LLVM doesn’t use it, so it occurs the error. If my assumption is right, do I need to rewrite the toolchain.nix ? or just add some linker flags in the CMakeLists.txt
Any idea ? thanks.
