[Libusbx-devel] Compiling the libu

[Pradeepa Senanayake]

Hello,

We have a product which uses freescale iMX6 processor and the following
Linux BSP version.

***@freescale ~$ uname -a
Linux freescale 3.0.35-2666-gbdde708 #18 SMP PREEMPT Tue Sep 1 15:17:34 IST
2015 armv7l GNU/Linux

We are trying to install the latest libusbx package (1.0.18) to our system.
But we found out that there is a dependency for libudev. Since that lib is
not available in our current BSP we cannot install libusbx at the moment.

But we can install libusb 1.0.15 (which too has an issue which I will post
separately). Is there anyway we can disable the libudev dependency using
configure options and build the libusbx-1.0.18 package? Is the change from
1.0.15 to 1.0.18 substantial?

Thank you.

libusb versions 1.0.16 and later require at least netlink support on Linux.
You can pass configure the '--disable-udev' flag to select netlink instead.

There have been many changes from v1.0.15 to v1.0.18. The latest (libusb)
is now v1.0.20-rc2. I encourage you to try that.

For future issues, please use the libusb-devel mailing list instead of
libusbx-devel. libusbx is now obsolete.

Regards,
Chris

Hello Chris,

Thank you for the suggestion. We compiled libusb-1.0.19 using
--disable-udev option on our device. It works well.



Best Regards,
Pradeepa Senanayake.
