交叉编译libusb和libusb-compat-0.1.5

1. 下载libusb库:
https://jaist.dl.sourceforge.net/project/libusb/libusb-1.0/libusb-1.0.22/libusb-1.0.22.tar.bz2

2. 编译安装libusb:
tar -xvf ./libusb-1.0.22.tar.bz2
cd ./libusb-1.0.22
mkdir build
./configure --prefix=/home/chy/Downloads/libusb-1.0.22/build CC=mips-linux-gnu-gcc --host=mips-linux-gnu --build=i686-linux --disable-udev
make -j4
make install

3. 下载libusb-compat-0.1.5库:
https://sourceforge.net/projects/libusb/files/libusb-compat-0.1/libusb-compat-0.1.5/libusb-compat-0.1.5.tar.bz2

4. 编译安装libusb-compat:
tar -xvf ./libusb-compat-0.1.5.tar.bz2
cd ./libusb-compat-0.1.5
mkdir build
./configure --build=i686-linux --host=mips-linux-gnu --prefix=/home/chy/work/project/libusb-1.0.0/libusb-compat-0.1.5/build CC=mips-linux-gnu-gcc PKG_CONFIG_PATH=/home/chy/work/project/libusb-1.0.0/libusb-1.0.0-mips/lib/pkgconfig
make -j4
make install
