C ++代码和带有.cpp文件的bcm2835

Question

您好我正在使用带有代码的raspberry pi 2直接从Microsoft visual c ++ 2010中取出，我试图将它与bcm2835一起用于GPIO的输出但是我在编译和构建之后得到了

/tmp/ccGucgzr.o: In function `main':
Geany2.cpp:(.text+0x14): undefined reference to `bcm2835_init'
Geany2.cpp:(.text+0x3c): undefined reference to `bcm2835_gpio_fsel'

Geany2.cpp:(.text+0x64): undefined reference to `bcm2835_close
Compliation failed
collect2: ld returned 1 exit status

当我在LX终端编译和构建它时，这是不同的，因为我没有错误，但是当我这样做g ++ -o Geany2 Geany2.cpp -l bcm2835并且我正在使用的引脚时代码似乎不起作用下面没有看到的是我的代码副本。
