Hi,I'm relatively new to Altera and uClinux and I've run into a problem trying to use libusb. I currently have uClinux version 3.7.0 (git://sopc.et.ntust.edu.tw/git/linux-2.6.git) running on my DE2-115 board. I would like to use libusb to simplify interaction with hot-pluggable USB devices. I have been unable to make the libusb source (libusbx-1.0.17) using the linux-mmu toolchain (git://sopc.et.ntust.edu.tw/git/toolchain-mmu.git). I run into problems with udev when I try to configure with: ./configure --host=nios2-linux --disable-shared --enable-static --with-pci-ids-path=/home/jim/nios2-linux/uClinux-dist/user/pciutils --enable-debug LDFLAGS="-elf2flt=-s16000" CC=nios2-linux-gnu-gcc my configure fails with: checking libudev.h usability... yes checking libudev.h presence... yes checking for libudev.h... yes checking for udev_new in -ludev... no configure: error: "udev support requested but libudev not installed" I have spent several days trying to compile and install udev (various versions from udev1.32 -> udev1.82) with the nios2-toolchain but have been unsuccessful. Is anyone successfully using libusb on uClinux (with udev) Any assistance would be great.
