Its works!!! i need to cross compile and cp .h .so inside raspberry pi cross toolsmaster Below is what i try: Do let me know if i miss out anythings Thanks^^ download libusb latest version tar file.

version 1.0.8

$ TOOLCHAIN=/opt/FriendlyArm/toolchain/4.4.3/arm-none-linux-gnueabi
$ PATH=$PATH:$TOOLCHAIN/bin
$ CC='arm-none-linux-gnueabi-gcc -march=armv4t -mtune=arm920t'
$ CROSS_COMPILE=arm-none-linux-gnueabi-
$ export CC CROSS_COMPILE
$ tar xfv libusb-1.0.8.tar
$ cd libusb-1.0.8
$ ./configure --host arm-linux
$ make
$ cd libusb
$ cp libusb.h $TOOLCHAIN/arm-none-linux-gnueabi/include/
$ cp libusb.h $TOOLCHAIN/arm-none-linux-gnueabi/sysroot/include/
$ cp .libs/libusb-1.0.so $TOOLCHAIN/arm-none-linux-gnueabi/lib/
$ cp .libs/libusb-1.0.so $TOOLCHAIN/arm-none-linux-gnueabi/sysroot/lib/

THE TOOLCHAIN IS SET. for writing programs: add #include to use he library. compile using following:

$arm-linux-g++ myprog.cpp -o myapp -lusb-1.0

NOTE: DON'T MISSOUT ON "-lusb-1.0"

Solution 1

LD_LIBRARY_PATH is used by the linker not the compiler, and even then you should only add the path as far as the directory containing the required files. See http://stackoverflow.com/questions/558803/how-to-add-a-default-include-path-for-gcc-in-linux[^] for setting the path for include files.
