I pulled down the 2009_02_08 bz2 file from : http://linmodems.technion.ac.il/packages/intel/Philippe.Vouters/ and tried to compile under Karmic Koala. It appears the proc_dir_entry structure has changed significantly and now this source won't compile. abc@logikaldesktop:~/downloads/intel-536EP-2.56.76.0$ make clean cd coredrv; make clean make[1]: Entering directory `/home/abc/downloads/intel-536EP-2.56.76..0/ coredrv' rm -f *.ko .*.o.cmd *.mod.c .*.ko.cmd *.o *~ core Module.* modules.* rm -rf .tmp_versions make[1]: Leaving directory `/home/abc/downloads/intel-536EP-2.56.76.0/ coredrv' rm -f *.o *.ko abc@logikaldesktop:~/downloads/intel-536EP-2.56.76.0$ make 536 Module precompile check Current running kernel is: 2.6.31-3-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 uname -r|grep "2.6" && \ cd coredrv && make 536core_26 && \ cp Intel536.ko .. && cd .. && \ strip --strip-debug Intel536.ko && \ exit; \ ls Intel536.ko >/dev/null 2>&1 || uname -r | grep "2.6" && echo "Failed to build driver" && exit; \ if [ ]; then \ cd coredrv; make TARGET=TARGET_SELAH KERNEL_SOURCE_PATH= "PSTN_DEF=-DTARGET_SELAH -DTARGET_LINUX -DLINUX" 536core; \ else \ cd coredrv; make TARGET=TARGET_SELAH KERNEL_INCLUDES=/lib/ modules/`uname -r`/build/include \ "PSTN_DEF=-DTARGET_SELAH -DTARGET_LINUX -DLINUX" 536core; \ fi ; \ cp Intel536.o .. ; \ if [ -a /boot/vmlinuz.version.h ]; then \ cp /boot/vmlinuz.version.h /lib/modules/`uname -r`/build/ include/linux/version.h;\ fi 2.6.31-3-generic make[1]: Entering directory `/home/abc/downloads/intel-536EP-2.56.76.0/ coredrv' make -C /lib/modules/2.6.31-3-generic/build SUBDIRS=/home/abc/ downloads/intel-536EP-2.56..76.0/coredrv modules make[2]: Entering directory `/usr/src/linux-headers-2.6.31-3-generic' CC [M] /home/abc/downloads/intel-536EP-2.56.76.0/coredrv/coredrv.o /home/abc/downloads/intel-536EP-2.56.76.0/coredrv/coredrv.c: In function ‘create_hamproc’: /home/abc/downloads/intel-536EP-2.56.76.0/coredrv/coredrv.c:785: error: ‘struct proc_dir_entry’ has no member named ‘owner’ make[3]: *** [/home/abc/downloads/intel-536EP-2.56.76.0/coredrv/ coredrv.o] Error 1 make[2]: *** [_module_/home/abc/downloads/intel-536EP-2.56.76.0/ coredrv] Error 2 make[2]: Leaving directory `/usr/src/linux-headers-2.6.31-3-generic' make[1]: *** [536core_26] Error 2 make[1]: Leaving directory `/home/abc/downloads/intel-536EP-2.56.76.0/ coredrv' 2.6.31-3-generic Failed to build driver I took a look at proc_fs.h and see it now has struct proc_dir_entry { unsigned int low_ino; unsigned short namelen; const char *name; mode_t mode; nlink_t nlink; uid_t uid; gid_t gid; loff_t size; I'm going to power down and try my smartlink modem now. -- Roland Hughes, President Logikal Solutions (630)-205-1593 (cell) http://www.theminimumyouneedtoknow.com http://www.infiniteexposure.net http://www.logikalsolutions.com
