【问题描述】：
我需要用我的程序编译库（只是 main.cpp）。该库是 BlackLib 2.0（已经有 how to compile blacklib (c++)，但我无法重现结果......也许我误解了一些东西）。
无论如何，重要的3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 & .h ... 和 main.cpp）都在 1 个文件夹中：
/home/martin/uart/uart_5#
3) 编译文件的命令（直接在 BeagleBone Black 上）
g++ *.cpp -o main -std=c++11
问题：

我有点绝望。 BackLib FAQ 也无济于事。
