I'm trying to launch the example code from aligned alloc:
#include <cstdio>#include <cstdlib>int main(){ int* p1 = static_cast<int*>(std::malloc(10*sizeof *p1)); std::printf("default-aligned address: %p\n", static_cast<void*>(p1)); std::free(p1); int* p2 = static_cast<int*>(std::aligned_alloc(1024, 1024)); std::printf("1024-byte aligned address: %p\n", static_cast<void*>(p2)); std::free(p2);}My compilers give me this error:
$ g++-mp-8 main.cpp -std=c++17main.cpp:10:38: error: no member named 'aligned_alloc' in namespace 'std' int* p2 = static_cast<int*>(std::aligned_alloc(1024, 1024));I am working with macOS High Sierra 10.13.6 and tried to compile this code with Macport's GCC 7.3.0, 8.2.0 and CLang (Apple LLVM version 10.0.0), they all produce the same error.
Edit: It doesn't work with either std:: present or not.
Edit2: I installed macOS Mojave and that did not fix the problem. I hoped it'll reinstall macOS's toolchain but it didn't. So I guess I cannot accept provided answers until I get a more specific one.
