Cross compile the LIBUSB and examples

[Author:bo Shen <[email Protected]>]

Assume you has the cross toolchain installed on your Linux host, where I use Ubuntu 12.04 with ARM-LINUX-GNUEABIHF-GCC ins Talled. (If not, here is the command)

--->8---

For the SoC support hard float point

$ sudo apt-get install GCC-ARM-LINUX-GNUEABIHF

For the SoC only support soft float point

$ sudo apt-get install GCC-ARM-LINUX-GNUEABIHF

---8<---

Then set the environment

--->8---

$ Export Arch=arm

$ Export cross_compile=arm-linux-gnueabi-

---8<---

The following steps is real to build the LIBUSB.

1. Get The source code

$ git clone git://git.libusb.org/libusb.git

2. Configure the source

2.1 Edit The autogen.sh file, remove following lines

--->8---

./configure--enable-maintainer-mode--enable-debug-log \
--enable-examples-build "[Email protected]"

---8<---

2.2 Then run the autogen.sh script

$./autogen.sh

2.3 Configure The Libusb

$./configure--host=arm-linux-gnueabihf---prefix=/tmp/_install--enable-examples-build

Note:the--enable-examples-build is used to generate the Makefile.

2.4 Make

$ make

3. Build the examples

$ CD Examples

$ arm-linux-gnueabihf-gcc-i/tmp/_install/include/libusb-1.0-l/tmp/_install/lib/-lusb-1.0-o Listdevs LISTDEVS.C

If you meet the error: ' Can not find the Libusb.h ', please edit the LISTDEVS.C and change the following lines:

From #include <libusb.h> to #include "libusb.h"
