Dear all, after reading 'Documentation/kbuild/kconfig-language.txt' several times, I dare ask in this mailing list for help: In 2.4's Config.in, there was the possibility to 'define_tristate' a configuration setting depending on another one. I assume this feature must be available in 2.6's Kconfig too. However, I cannot find any information that helps me in this regard. In concrete: in 2.4 I have had: if [ "$CONFIG_EXPERIMENTAL" = "y" ]; then dep_tristate ' PromethOS ANN (ipv4) (EXPERIMENTAL)' \ CONFIG_IP_NF_PROMETHOS $CONFIG_IP_NF_IPTABLES if [ "$CONFIG_IP_NF_PROMETHOS" != "n" ]; then define_tristate CONFIG_IP_NF_PROMETHOS_TARGET \ $CONFIG_IP_NF_PROMETHOS In 2.6, so far I have: config IP_NF_PROMETHOS tristate 'PromethOS ANN (ipv4)' depends on EXPERIMENTAL && IP_NF_IPTABLES help This options makes Linux a high-performance active network node. I have not understood so far, how I can set - boolean values - define_tristate in 2.6's Kconfig. For any brief help, I would be very thankful! wbr, Lukas -- Lukas Ruf | Wanna know anything about raw | <http://www.lpr.ch> | IP? -> <http://www.rawip.org> | eMail Style Guide: <http://www.rawip.org/style.html>| -- Kernelnewbies: Help each other learn about the Linux kernel.
