Question

我正在尝试以“ hello world”为例来设置交叉编译系统。

代码看起来像这样：

#include <iostream>
int main() {
    int count = 0;
    count++;
    std::cout << count << " ARM Test running..." << std::endl;
    return 0;
}

specs host system specs target system 使用的IDE版本：Oxygen.3a版本（4.7.3a）

我已经安装了arm-none-eabi-g ++。如果我在命令行中输入arm-none-eabi-g++ -v，则会得到以下输出：

@ubuntu：/ opt / toolchains $ arm-none-eabi-g ++ -v使用内置规范。

COLLECT_GCC = arm-none-eabi-g ++

COLLECT_LTO_WRAPPER = / usr / bin /../ lib / gcc / arm-none-eabi / 7.3.1 / lto-wrapper

目标：arm-none-eabi配置为：

线程模型：单   gcc版本7.3.1 20180622（发行版）[ARM /嵌入式7分支修订   261907]（用于Arm嵌入式处理器的GNU工具7-2018-q3-update）

构建代码时，我收到不知道如何解决的Eclipse命令窗口中的以下错误消息：

 16:34:49 **** Build of configuration Debug for project ARM ****
    make all

    src/subdir.mk:18: recipe for target 'src/ARM.o' failed

    16:34:51 Build Finished (took 1s.229ms)

此错误是否与链接器问题有关？

在Odroid-xu4上从Linux VM进行交叉编译
