如何编译blacklib（c ++） [英] how to compile blacklib (c++)

问题描述

我正在运行beaglebone，想要编写一个程序来采样ADC。我尝试使用blacklib（ http://blacklib.yigityuce.com/index.html ） 从这里。我克隆了git：
https://github.com/yigityuce/BlackLib

I am running a beaglebone and want to write a program to sample the ADC. I am trying to use the blacklib (http://blacklib.yigityuce.com/index.html) from here. I cloned the git: https://github.com/yigityuce/BlackLib

并试图使用

g++ exampleAndTiming.cpp -std=c++11

但是这会给我一大堆错误：

This however gives me a ton of errors like these:

In file included from exampleAndTiming.cpp:33:0:
exampleAndTiming/exampleAndTiming_GPIO.h: In function 'void exampleAndTiming_GPIO()':
exampleAndTiming/exampleAndTiming_GPIO.h:97:12: error: 'sleep' was not declared in this scope
     sleep(1);
            ^
In file included from exampleAndTiming.cpp:34:0:
exampleAndTiming/exampleAndTiming_ADC.h: In function 'void exampleAndTiming_ADC()':
exampleAndTiming/exampleAndTiming_ADC.h:67:16: error: 'usleep' was not declared in this scope
     usleep(1000);
                ^

所以我包含unistd.h（在exampleAndTiming.cpp）得到如下错误：

so I include unistd.h (in exampleAndTiming.cpp), but then I get errors like these:

/tmp/ccbgiXE9.o: In function `exampleAndTiming_GPIO()':
exampleAndTiming.cpp:(.text+0x50): undefined reference to `Timing::startMeasure(std::string)'
exampleAndTiming.cpp:(.text+0x80): undefined reference to `BlackLib::BlackGPIO::BlackGPIO(BlackLib::gpioName, BlackLib::direction, BlackLib::workingMode)'
exampleAndTiming.cpp:(.text+0xbc): undefined reference to `Timing::endMeasure(std::string)'
exampleAndTiming.cpp:(.text+0xec): undefined reference to `BlackLib::BlackGPIO::BlackGPIO(BlackLib::gpioName, BlackLib::direction, BlackLib::workingMode)'
exampleAndTiming.cpp:(.text+0x104): undefined reference to `BlackLib::BlackGPIO::BlackGPIO(BlackLib::gpioName, BlackLib::direction, BlackLib::workingMode)'
exampleAndTiming.cpp:(.text+0x11c): undefined reference to `BlackLib::BlackGPIO::BlackGPIO(BlackLib::gpioName, BlackLib::direction, BlackLib::workingMode)'
exampleAndTiming.cpp:(.text+0x158): undefined reference to `Timing::startMeasure(std::string)'

我一直在看一些库示例和编译它，不能理解这一切。我之前编译了大量的c ++和c程序，但我不能让这个工作。

I've been looking at some library examples and compiling it, but I cannot make sense of it all. I've compiled plenty of c++ and c programs before, but I can't get this one to work. So any help will be appreciated.

推荐答案

似乎我设法自己修复，一些nooblike行为不包括所有的cpp文件，但是更多，我还需要添加#include到BlackCore.h以避免大量未定义的函数错误。

It seems I managed to fix it myself, some nooblike behaviour not including all the cpp files, but even more, I also needed to add #include to BlackCore.h to avoid tons of undefined function errors.

最终命令：

g++ exampleAndTiming.cpp exampleAndTiming/Timing.cpp BlackADC.cpp BlackCore.cpp BlackGPIO.cpp BlackI2C.cpp BlackPWM.cpp BlackSPI.cpp BlackUART.cpp -std=c++11

我可能需要make一个makefile来单独编译库，一些更多的挖掘和学习。

I'd probably need to make a makefile to compile the library seperately, time to do some more digging and learning.
