All Very strange. It is some sort of permissions issue and maybe a Ubuntu bug. John, Within the new agrsm code package just $ sudo chown -R YourLoginName * so that you own all the files. $ gedit Makefile go down to the section clean: and below rm -f HDA.o add a line rm -f hda.o Note that the indentations MUST be down with TAB and not spaces Do the same in the section distclean; Clean up with $ make distclean After which $ ls -l shouldn't display agrmodem.ko and agrserial.ko Next $ make module which should now succeed. The curious puzzle is that if one does $ make distclean as before, but $ sudo make module Then the compile fails as you reported. I haven't had time to determine why. Separately I'll send you an installer package with the same code, agrsm06pci-Version.deb If is dkms enabled, so if the dkms package is installed on your System, all updates will be automagic MarvS If dkms is not installed, cd into the source folder written to /usr/src/ following $ sudo dpkg -i agrsm06pci*.deb Within $ make distclean $ make module should be successful. I haven't played with the $ sudo agrinst Best to copy the drivers manually into the /lib/modules/ tree The curious puzzle remains that while: On Wed, Aug 26, 2009 at 8:49 AM, Marvin Stodolsky<marvin.stodolsky@xxxxxxxxx> wrote: > john, > > Kernel-source is not the issue, as I was able to do the compile under > one condition, but reproduced your failure under another condition. > See attached.
