Question

我正在尝试在Debian（Raspberry Pi Raspbian）上编译一个C程序ipad_charge（https://github.com/mkorenkov/ipad_charge）。它是为Ubuntu编写的，我在那里安装它没有任何问题。在Debian上，我得到编译错误;

gcc -Wall -Wextra ipad_charge.c -lusb-1.0 -o ipad_charge
ipad_charge.c: In function ‘set_charging_mode’:
ipad_charge.c:37:3: warning: implicit declaration of function ‘libusb_strerror’ [-Wimplicit-function-declaration]
ipad_charge.c:37:3: warning: format ‘%s’ expects argument of type ‘char *’, but argument 3 has type ‘int’ [-Wformat]
ipad_charge.c:43:3: warning: format ‘%s’ expects argument of type ‘char *’, but argument 3 has type ‘int’ [-Wformat]

ipad_charge.c: In function ‘main’:

/tmp/cc1hdopk.o: In function `main':
ipad_charge.c:(.text+0x5fc): undefined reference to `libusb_strerror'
collect2: ld returned 1 exit status
Makefile:2: recipe for target 'ipad_charge' failed
make: *** [ipad_charge] Error 1

当我查看代码时，似乎libusb正在进行繁重的工作。我的猜测是我需要运行一个更新的libusb版本才能在Debian上编译。既然我想继续使用Debian stable，有人知道如何在Debian中安装更新版本的libusb，这样我才能让这个程序运行起来吗？我是否正确理解了问题，还是存在其他问题？

您可以下载source code of libusb，进行编译并安装（例如在/usr/local/中），然后使用

编译ipad_charge.c

  gcc -Wall -Wextra -O -g -v -H -I/usr/local/include/ -L /usr/local/lib \
       ipad_charge.c -lusb-1.0 -o ipad_charge

请确保-H告诉您使用了正确的包含文件（在/usr/local/中），-v（甚至可能是-Wl,-v）告诉您正确的库（在/usr/local/中）被使用。
