Я хочу сделать кросс-компиляцию следующего исходного файла (Foo.cpp)
#include <cstdint>
int Foo()
{
uint32_t bar = 0;
return bar;
}
с i686-w64-mingw32 и arm-none-eabi в системе Windows 10.Поэтому я использую следующий пакетный файл
@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%"

Так что для i686-w64-mingw32 достаточно указать местоположениекомпилятор по пути, но для arm-none-eabi компилятор clang не может найти заголовки кросс-компиляции.
Кто-нибудь знает, как настроить clang для arm-none-eabi ?
Почему происходит следующее?
Цель: arm-none - eabi
Разве это не должно быть?
Цель: arm-none-eabi
Спасибо!
