我将整个hidapi-0.7.0下载（https://github.com/downloads/signal11/hidapi/hidapi-0.7.0.zip）解压缩到我的项目目录中，然后将hidapi-0.7.0/hidapi/hidapi.h和hidapi-0.7.0/linux/hid-libusb.c添加到我的项目中。所以他们现在出现在我的*.pro文件中。如何在Qt Creator中使用HIDAPI？
我安装了libusb-1.0（sudo apt-get install libusb-1.0-0-dev）并试图构建项目。它编译没有问题，但链接这样做：

自述只是说：
要使用HIDAPI，简单地丢弃或者hid.c或藏-libusb.c到您的 应用程序并使用Makefile中的构建参数进行构建。
这没有帮助。 （？我如何确保QTC的生成Makefile文件的工作原理是，当我甚至不明白摆在首位的Makefile）
的网站上说：
构建指令
。 ..
Linux：
更改到linux /目录并运行make。
，但它做同样的事情：

我仍然失去了一些东西（我希望如此），或者是HIDAPI 0.7.0实际上破碎，看到它甚至不从盒子中正确构建？每@ eyllanesc的评论

不喜欢，要么，但至少这是一个不同的错误，因此它可能是某种形式的进度。不幸的是，我不知道这是什么意思。
执行：'sudo apt-get install libudev-dev libusb-1.0-0-dev libfox-1.6-dev'和'make clean && make' – eyllanesc
