[Nut-upsuser] libusb not recognized?

Wed Nov 16 02:13:45 UTC 2011

Hi Arnaud,

I tried libusb-0.1.0 and libusb-0.1.9. Neither of them worked.
My instiall logs attached. And here is my install sequence (log files are arranged by name):

libusb-0.1.0 log:
1. configure libusb-0.1.0:
-- File: 01-libusb-0.1.0_config.log
# ./configure --host=arm-mv5sft-linux-gnueabi --prefix=/mnt/ARM_FS
2. make libusb-0.1.0:
-- File: 02-libusb-0.1.0_make.txt
# make
3. install libusb
-- File: 03-libusb-0.1.0_makeInatall.txt
# make install
4.
-- configure NUT
-- File: 04-NUT_config.log
# export PKG_CONFIG_PATH=/mnt/ARM_FS/lib/pkgconfig
./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

Also attach sequence of installing libusb-0.1.12 with same commands, from file 05 to 08.

Any suggestions?

Thanks!

Best Regards,
Andrew

and as told 2 times also, please use libusb 0.1 not 1.0, since we're not yet compatible with the latter.

cheers,

 Hello,

   I downloaded NUT ver 2.6.2 and tried it on my Linux development board. when I configure and it notified me that "USB drivers requested, but libusb not found."
   Then I download libusb v1.0.8 and install it to my board, and re-configure NUT, still "USB drivers requested, but libusb not found". I look into config.log, and found that usb.h not found.
   I tried Google and install libusb-compat. Then usb.h was found, and libusb version is recognized. However, still "USB drivers requested, but libusb not found"...

Correct, NUT is only designed to work with the libusb-0.1 API (provided by libusb-compat).

   I could not fing any more solution of that. Therefore, I turn to developers. config.log is attached. Here are my hardware and software configurations:
CPU: Marvell 88E6281 with ARM926ejs
Linux ver: 2.6.31.8
cinfigure commnd:
./configure --with-usb --with-doc \
--host=arm-mv5sft-linux-gnueabi \
--prefix=/mnt/ARM_FS \

How did you install libusb-1.0? It appears that the actual .so file was not installed properly:

configure:7259: checking for libusb version via pkg-config
configure:7278: result: 0.1.12 found

[...]

The libusb-1.0.so.0 file should be in the same directory as libusb.so, meaning that -rpath* options shouldn't be necessary. But if there is something special about the way libusb was installed (packaging, etc.) then you might need to fiddle with those options.

  Any suggestions?
  Thanks!
