Have you compiled javax.usb with the 2.6.8.1 kernel headers? Right now there are #defines that make the JNI work with 2.4 or 2.6, depending on what you compile it with. The javax-usb-ri-linux JNI makefile uses the CINCLUDES variable, so if you set it to the location of the 2.6.8.1 kernel header files, it should pick up the right values. For example if you have the kernel source at /usr/src/linux-2.6.8.1 (and are using bash shell):
export CINCLUDES=-I/usr/src/linux-2.6.8.1/include ant clean jars does that work? On Thu, 9 Sep 2004, Susheel Yadav wrote: >Hi, >I am trying to get my Microtek Scanmaker 5600 working >with linux.
