    Trying to install Parallel Tools on Gentoo

    gcc has an error compiling prl_eth/pvmnet

    "/usr/lib64/parallels-tools/kmods/prl_eth/pvmnet/pvmnet.c:194:3: error: 'struct ethtool_ops' has no member named 'get_settings'; did you mean 'get_strings'?"

    does anyone know what this means?

    This use to install fine before I did some package updates...

    -- below is the full error on install...

    I also met the same problem and just fixed it. Hope my solution can help you.
    This problem is caused by ethtool deletingthe member variable ".get_settings" of struct ethtool_ops. So we just need to delete ".get_settings = pvmnet_get_settings,".
    More specific steps are as follows:

    > cp -r /mnt/cdrom ~/tmp
    > cd ~/tmp/kmods
    > tar xvf ./prl_mod.tar.gz
    > vim prl_eth/pvmnet/pvmnet.c
    | and replace the line (or just delete the line)
    | 	.get_settings = pvmnet_get_settings,
    | with
    | 	.get_settings = pvmnet_get_settings,
    | #endif
    > tar -zcvf prl_mod.tar.gz ./ dkms.conf Makefile.kmods
    > cd ~/tmp
    > ./install --install
