我在Ubuntu Linux中使用代码块。我想用libusb库编写程序。我在系统中有这个文件，但IDE中的编译器找不到这个文件。我在这个文件中添加了“构建选项”，这没有帮助。这个问题的解决方案是什么？libusb在IDE中不可见
#include <libusb.h>
更新：
dpkg -L libusb-dev显示如下：

但是，当我改变#include <libusb.h>到#include <usb.h>，并尝试编译这段代码：
#include <stdio.h>
#include <stdlib.h>
#include <usb.h>
int main(){
usb_init();
printf("Hello world!\n");
return 0;
}
我得到的以下错误：
undefined reference to 'usb_init'
由于Borland已经无关的代码块，和Borland C++编译器只存在于Win32，我相信一句话'Borland公司应该从你的问题被丢弃？ –
感谢您的回复。我使用gcc 4.4.5，他的thorow“文件或目录未找到”免费翻译成英文。 我在OS libusb-dev包中。 – user902691
检查我更新的答案。我有一种直觉，你正在指定错误的头文件名。 –
