问题描述
我试图编译通过libusb的包中提供的示例libusb.c（如果你延胡索源$ C $ C）
I am trying to compile the example libusb.c provided by libusb package (if you dl the source code.)
它不工作，至少可以说。
It doesn't work to say the least.
#include <stdio.h>
#include <sys/types.h>
#include <libusb/libusb.h>
这会导致它失败，没有的libusb / libusb.h 是 usb.h ，所以我改变这种状况。它失败在新的和创新的方式。
That causes it to fail, there is no libusb/libusb.h it's usb.h, so I change that. And it fails in new and innovative ways.
我在复制的文件，准确，并把它命名为example.c
I've copied the file over, exactly, and named it example.c
我使用这些命令和变化：
I am using these commands and variations:
gcc -o example example.c -lusb -L /usr/lib/libusb.a
gcc -o example example.c -lusb -L /usr/lib/libusb.so
在编译时，我得到的错误是：
The errors I get when compiling are:
example.c:25: error: expected ‘)’ before ‘*’ token
example.c: In function ‘main’:
example.c:46: error: ‘libusb_device’ undeclared (first use in this function)
example.c:46: error: (Each undeclared identifier is reported only once
example.c:46: error: for each function it appears in.)
example.c:46: error: ‘devs’ undeclared (first use in this function)
Line 25: static void print_devs(libusb_device **devs)
Line 46: libusb_device **devs;
起初我也跟着教程，和无法编译，或多或少相同的方式，所以我决定只是尝试提供的示例，而失败了。
At first I followed a tutorial, and that failed to compile, in more or less the same ways, so I decided to just try the provided example, and that failed.
谁能帮我吗？解释什么是我做错了，因为我失去了在这一个。
Can anyone help me out? Explain what I am doing wrong, cause I am lost on this one.
推荐答案
这是我不得不在Debian做。它应该是在Ubuntu至少是相似的。
This is what I had to do on Debian. It should be at least similar in Ubuntu.
安装的libusb-1.0-0-dev的
而不是：
#include <libusb/libusb.h>
做的：
#include <libusb.h>
与编译：
gcc example.c `pkg-config --libs --cflags libusb-1.0`
