Re: [Dnsmasq-discuss] dnsmasq compilation and dependencies: compilation macros and help
Kevin, could be a misunderstanding? My original question is about dnsmasq --help I don't need to discover how dnsmasq is built. So I don't need to parse dnsmasq -v Let talk about end users. Example, I disabled dhcp. I expect for the users running dnsmasq --help they don't see any help about dhcp features. However, thank you for your suggestion. It suggests to me to check with dnsmasq 2.80.

Hi Massimo, Yes it probably should be. If it is any help, in openwrt we look (& parse) the output of ‘dnsmasq -v’ at run-time to determine what build-time options have been selected. Maybe you also could use this approach?

Hi Geert Ehm ... I mistyped writing the email. I check my script: make COPTS="-DNO_AUTH -DNO_DHCP -DNO_INOTIFY -DNO_IPV6 -DNO_SCRIPT -DNO_TFTP" A quick glance at the source code: it seem to me the help arguments aren't conditioned by the compilation macros.

[Dnsmasq-discuss] dnsmasq compilation and dependencies
Hi I have some servers with linux 2.6.18. I know... but I cannot upgrade because of legacy applications, it's ok for us, they are only for intranet usage. Pls a few questions: 1) configure and compile vs dnsmasq --help I want only the DNS daemon, a minimal version (not authoritative). I tried this: make COPTS="-DNO_AUTH DNO_DHCP -DNO_INOTIFY -DNO_IPV6 -DNO_SCRIPT -DNO_TFTP" and it succeded. However running src/dnsmasq --help I still see some options regarding the excluded features (like dhcp). Is this ok ? 2) dependencies >From the http://www.thekelleys.org.uk/dnsmasq/CHANGELOG I don't understand the dependencies on shared libraries. Example: an excerpt from ver 2.79 Tidy up Crypto code, removing workarounds for ancient versions of libnettle. We now require libnettle 3. With the aforementioned options (1), is libnettled required? The output of ldd src/dnsmasq shows only linux-vdso.so.1 => (0x2aaab000) libc.so.6 => /lib64/libc.so.6 (0x003ed480) /lib64/ld-linux-x86-64.so.2 (0x003ed440) On linux 2.6.18 I tried to download and compile libnettle3, but there are too many broken dependencies. Is it possibile to use dnsmasq 2.80 without this library?
