Hi, Chaies

Here are my install sequence and logs.


1. Installing libusb:
# ./configure --host=arm-mv5sft-linux-gnueabi --prefix=/mnt/ARM_FS

> /* "/mnt/ARMFS" is my ARM board's NFS directory */
> config.log remaned as "libusb_config.log" and attached
# make
> print message "libusb_make.txt"
# make install
> print message  "libusb_install.txt"

2. installing libusb-compat
# export PKG_CONFIG_PATH=/mnt/ARM_FS/lib/pkgconfig
# ./configure --host=arm-mv5sft-linux-gnueabi --prefix=/mnt/ARM_FS
> config.log remaned as "libusb-c_config.log"
# make
> "libusb-C_make.txt"
# make install
> "libusb-C_install.txt"

3. configure NUT
./configure --with-usb --with-doc \
--host=arm-mv5sft-linux-gnueabi \
--prefix=/mnt/ARM_FS \
--with-usb-libs=-L/mnt/ARM_FS/lib \
--with-usb-includes=-I/mnt/ARM_FS/include
> "NUT_config.log" attached

all file marked by ">" are gzipped and attached

Do you mean that I used inappropriate libusb? Actually, I am quite confused by libusb and libusb-compat.


Best Regards
