libusb在linux下的配置

记录自己的开发经验以便日后查看

libusb下载与编译

1.在官网下载libusb-1.0.23 2.解压tar -xvf libusb-1.0.23.tar.bz2 3../configure 4.make 5.sudo make install

在加载配置和编译的时候难免会遇到报错，执行下面代码下载

sudo apt-get install libusb-dev sudo apt-get install libusb-1.0-0-dev sudo apt-get install libudev-dev

生成的头文件在/usr/local/include/libusb-1.0 生成的库在/usr/local/lib

写一个demo程序来测试

#include <stdio.h> #include <sys/types.h> #include <libusb.h> static void print_devs(libusb_device **devs) { libusb_device *dev; int i = 0; while ((dev = devs[i++]) != NULL) { struct libusb_device_descriptor desc; int r = libusb_get_device_descriptor(dev, &desc); if (r < 0) { fprintf(stderr, "failed to get device descriptor"); return; } printf("%04x:%04x (bus %d, device %d)\n", desc.idVendor, desc.idProduct, libusb_get_bus_number(dev), libusb_get_device_address(dev)); } } int main(void) { libusb_device **devs; int r; ssize_t cnt; r = libusb_init(NULL); if (r < 0) return r; cnt = libusb_get_device_list(NULL, &devs); if (cnt < 0) return (int) cnt; print_devs(devs); libusb_free_device_list(devs, 1); libusb_exit(NULL); return 0; }

在编译时候加入动态库与头文件gcc example.c -I /usr/local/include/libusb-1.0 -L /usr/local//lib -lusb-1.0
