libusb的以及如何使用它包在Ubuntu [英] Libusb and how to use its packages in Ubuntu
问题描述
我已经使用以下命令安装libusb的。我不知道这是否是正确与否,命令是
命令和apt-get安装的libusb-dev的
在我已经安装(如果已经安装或没有,因为我的Ubuntu的初级用户,我不知道),我想知道我会如何使用图书馆,因为我写的一些示例code这使用< libusb.h>,但是当我编译C ++文件中使用
G ++ test_libusb.cpp
这引发以下错误,
test_libusb.cpp:2:20:致命错误:libusb.h:没有这样的文件或目录汇编终止
。
块引用>我无言以对做什么。我不能在互联网上找到任何来源去的这条底线...
我想知道这里两件事情:
- 如何添加libusb库中的C / C ++,所以我可以使用<?libusb.h>
- 将一些样本code是什么?只有几行,看看libusb的工作......
解决方案在看一看<一个href=\"http://packages.debian.org/wheezy/i386/libusb-dev/filelist\">http://packages.debian.org/wheezy/i386/libusb-dev/filelist:您要包括的文件是
usb.h
。此外,你必须告诉编译器哪里能找到编译后的库函数:-lusb
添加到编译器命令行,使其加载libusb.so
。I have installed libusb by using the following command. I am not sure if it was right or not and the command was
sudo apt-get install libusb-dev
Once I have installed (and I am not sure if it has installed or not because I am a novice user of Ubuntu), I want to know how would I use the library, because I write some sample code which uses <libusb.h>, but when I compile that C++ file using
g++ test_libusb.cpp
that throws the following error,
test_libusb.cpp:2:20: fatal error: libusb.h: No such file or directory compilation terminated.
I am clueless what to do. I can't find any source on the Internet to get to the bottom of this...
I want to know two things here:
- How do I add the libusb library in C/C++ so I can use <libusb.h>?
- What would some sample code be? Only a few lines to see if libusb is working...
解决方案Have a look at http://packages.debian.org/wheezy/i386/libusb-dev/filelist: The file you want to include is
usb.h
. Also, you'll have to tell the compiler where it can find the compiled library functions: Add-lusb
to the compiler command line to make it loadlibusb.so
