SUSE12.2 编译usbutils

折腾了两天，终于交叉编译出来lsusb命令可以在单板上跑起来，记录一下

1：编译eudev
下载地址：https://dev.gentoo.org/~blueness/eudev/，版本eudev-3.2.2
#export EUDEV_ROOT=`pwd`
#./configure CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ --host=arm-linux --prefix=$PWD/_install --disable-blkid --disable-kmod
#make -j2
#make install
CFLAGS=-I$EUDEV_ROOT/_install/include LDFLAGS=-L$EUDEV_ROOT/_install/lib
#export PKG_CONFIG_PATH=$PWD/_install/lib/pkgconfig/
查看_install目录

2：编译libusb
下载地址：https://github.com/libusb/libusb/releases?after=v1.0.21-rc4，用的版本为libusb-1.0.18
#export LIBUSB_ROOT=`pwd`
./configure CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ --host=arm-linux CFLAGS=-I$EUDEV_ROOT/_install/include LDFLAGS=-L$EUDEV_ROOT/_install/lib
# make -j2
# make install
查看_install目录
-lpthread

3:编译usbutils,版本usbutils-012
#export PKG_CONFIG_PATH=$EUDEV_ROOT/_install/lib/pkgconfig/:$LIBUSB_ROOT/_install/lib/pkgconfig/
./configure CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ --host=arm-linux --prefix=$PWD/_install
# make -j2
# make install

将新编译出来的lsusb命令拷贝至运行环境(同时需要将对应的libusb库也拷贝至运行环境，同时配置LD_LIBRARY_PATH)

为方便执行，编译为静态库
./configure CC=arm-linux-gnueabihf-gcc CXX=arm-linux-gnueabihf-g++ --host=arm-linux --prefix=$PWD/_install CFLAGS='-g -O2 -static'
修改Makefile文件，在UDEV_LIBS中，添加对pthread库的调用
例如：
UDEV_LIBS = -LCROSS_TOOLCHAINS_ROOT/arm-linux-gnueabihf/libc/usr/lib -lpthread -L/usr1/wangjunhui/usbutils/eudev-3.2.2/_install/lib -ludev
