用libusb编译? [英] Compiling with libusb?

问题描述

不管我跑什么，

./main.c:1:10: fatal error: libusb.h: No such file or directory
 #include "libusb.h"
          ^~~~~~~~~~
compilation terminated.

尝试过的事情

gcc ./main.c -l/usr/include/libusb-1.0/
gcc ./main.c -l/usr/include/
gcc ./main.c -L/usr/include/libusb-1.0/
gcc ./main.c -L/usr/include/

如果我尝试

#include "libusb-1.0/libusb.h"

代替

#include "libusb.h"

它可以编译，但是我可以得到

It compiles, but I get

/tmp/ccLn3qR2.o: In function `main':
main.c:(.text+0x17): undefined reference to `libusb_init'
main.c:(.text+0x2b): undefined reference to `libusb_open_device_with_vid_pid'
main.c:(.text+0x46): undefined reference to `libusb_release_interface'
main.c:(.text+0x55): undefined reference to `libusb_close'
collect2: error: ld returned 1 exit status

我在

gcc ./main.c -I/usr/include/libusb-1.0

我看到很多人遇到类似的错误，但我可以找到解决方案.这些似乎是此处记录的.

I see a lot of people getting similar errors, but I can find the solution. These seem to be documented here.

推荐答案

最终起作用的是在 .h 文件中指定了路径，

What ended up working, was specifying the path in the .h file,

#include "libusb-1.0/libusb.h"

其中包含/usr/include/libusb-1.0/libusb.h .然后，用

gcc ./main.c -lusb-1.0
