Gregor,
Can you take a look at this to see if I did this correctly? I'm no
autoconf hero, so before I push I'd like some feedback.
The main reason for these changes is that I need to build v4l2-ctl for
an embedded system and rather than having to hack on my side, I prefer
to add configure options that do what I (and probably others) want.
Regards,
Hans

This patch adds new configure options to do this: --disable-v4l2-compliance-libv4l --disable-v4l2-ctl-libv4l This is useful when building for an embedded system where you do not want to use the libv4l2 wrapper library. The capability to do this was already available, but not hooked up to the configure system.

Not sure about this patch. Maybe the better would be to see if we could add a poor man's argp, instead, for those broken userspace systems. Weird enough, a quick search on Google for "argp replacement android" actually showed an argp.h at some android source: https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.7-4.6/+/jb-dev/sysroot/usr/include/argp.h This site has an standalone argp imported from glibc-2.2, according with its ChangeLog: https://github.com/jahrome/argp-standalone Static linking an standalone version is a little ugly. So, wee can do something simpler than that, as there is just one important function at argp: the one that calls a callback that will handle the command line options (argp_parse). This can be trivial to be implemented, specially if it would handle just the one letter parameters, as it would be just a callback. It can just ignore the help message functions like argp_help(), giving some error message and giving up. Eventually, just a small set of inline functions, plus adding the argp structures on a header would be enough.
