Question

我需要用我的程序（只是main.cpp）编译库。该库是BlackLib 2.0（已经有how to compile blacklib (c++)，但我无法重现结果......也许我误解了一些内容。）

无论如何，有三个要点：

1）main.cpp包括：

#include <iostream>
#include <unistd.h>

#include <BlackCore.h>
#include <BlackDef.h>
#include <BlackErr.h>
#include <BlackLib.h>
#include <BlackUART.h>

2）所有文件（库文件 - .cpp＆amp; .h ...和main.cpp）都在1个文件夹中：

/home/martin/uart/uart_5#

3）命令编译文件（直接在BeagleBone Black上）

g++ *.cpp -o main -std=c++11

问题：

我有点绝望。 BackLib FAQ也没有帮助。

Answer 1

我已将how to compile blacklib (c++)的答案发布在标题完整指南中如何直接在运行ANGSTROM的BEAGLEBONE BLACK（rev C）上编译BLACKLIB

Answer 2

您需要将头文件unistd.h添加到BlackUART.h

BeagleBone Black + BlackLib-程序+库编译
