Hello again, I seem unable to compile the Intel 536EP driver. I extracted it to /usr/src and ran make as root. Here is my output. # make 536 cd coredrv; make clean make[1]: Entering directory `/usr/src/intel-536-537/coredrv' rm -f *.ko .*.o.cmd *.mod.c .*.ko.cmd *.o *~ core Module.* modules.* rm -rf .tmp_versions make[1]: Leaving directory `/usr/src/intel-536-537/coredrv' rm -f *.o *.ko Module precompile check Current running kernel is: 2.6.31-14-generic /lib/modules... autoconf.h exists diff: /boot/vmlinuz.autoconf.h: No such file or directory autoconf.h matches running kernel diff: /boot/vmlinuz.version.h: No such file or directory version.h matches running kernel make[1]: Entering directory `/usr/src/intel-536-537' 2.6.31-14-generic make[2]: Entering directory `/usr/src/intel-536-537/coredrv' make -C /lib/modules/2.6.31-14-generic/build SUBDIRS=/usr/src/intel-536-537/core drv modules make[3]: Entering directory `/usr/src/linux-headers-2.6.31-14-generic' CC [M] /usr/src/intel-536-537/coredrv/coredrv.o CC [M] /usr/src/intel-536-537/coredrv/clmmain.o CC [M] /usr/src/intel-536-537/coredrv/rts.o CC [M] /usr/src/intel-536-537/coredrv/task.o CC [M] /usr/src/intel-536-537/coredrv/uart.o CC [M] /usr/src/intel-536-537/coredrv/wwh_dflt.o CC [M] /usr/src/intel-536-537/coredrv/locks.o CC [M] /usr/src/intel-536-537/coredrv/softserial_io.o CC [M] /usr/src/intel-536-537/coredrv/softserial_ioctl.o CC [M] /usr/src/intel-536-537/coredrv/softserial.o /usr/src/intel-536-537/coredrv/softserial.c: In function ‘softserial_background_event_handler’: /usr/src/intel-536-537/coredrv/softserial.c:365: error: request for member ‘ops’ in something not a structure or union /usr/src/intel-536-537/coredrv/softserial.c:374: error: request for member ‘ops’ in something not a structure or union make[4]: *** [/usr/src/intel-536-537/coredrv/softserial.o] Error 1 make[3]: *** [_module_/usr/src/intel-536-537/coredrv] Error 2 make[3]: Leaving directory `/usr/src/linux-headers-2.6.31-14-generic' make[2]: *** [536core_26] Error 2 make[2]: Leaving directory `/usr/src/intel-536-537/coredrv' 2.6.31-14-generic Failed to build driver make[1]: Leaving directory `/usr/src/intel-536-537' Stephen Pinker http://groups.google.com/group/ubuntu-modems?hl=en
