[Buildroot] missing kernel headers when compiling kismet

[Buildroot] missing kernel headers when compiling kismet

[Marc Egli]

configuring kismet fails with the following message:
checking for linux/wireless.h... (cached) no
configure: error: Failed to find a usable linux/wireless.h header for Linux Wireless Extensions.  Either your kernel headers are missing or are incorrect.  See config.log for the exact error.  Compiling without wireless headers must be explicitly disabled
make: *** [/emb/buildroot/output/build/kismet-2009-06-R1/.stamp_configured] Error 1

in the kismetwireless forum i found the following:
The configure script is pretty much straightforward: If you don't provide a --linux-headers parameter, it adds /lib/modules/!version!/build/include to the header search path. This is SUPPOSED to be the build environment of the running kernel, and as such is SUPPOSED to have linux/foo.h

now how can i give the kernelheader path to the configure script? and wich version do i have to use? i've found about 10 files named wireless.h in buildroot

thx for your help

Hmm, it builds here - Please post your config. Notice that the above
check has been cached, does it work if you run make flush; make?

problem solved. 
i did make flush again and now it works. but i did this 2 times this morning and it didn't help. i hope it builds again if i do a make clean this night.

Please give it a try and/or send your .config to the list so we can fix
the problem if there is one.

make clean and make did result in the same error i got before:
checking for linux/wireless.h... (cached) no
find ./ -name wireless.h gave me:
./output/toolchain/linux-2.6.31.6/include/linux/wireless.h
./output/toolchain/uClibc_dev/usr/include/linux/wireless.h
./output/toolchain/linux/include/linux/wireless.h

now i did only a make flush and again make and now it works. seems something is wrong with the config cache. i'll do a rebuild during the night and diff the config cache from now with the one wich leads to this error

Hmm, I don't see any issues here with building the network packages you
had enabled (the most obvious ones to check for linux/wireless.h). I see
you have some local lxde packages enabled, maybe one of those checks for
wireless? Could you try temporarily disabling them and doing a clean
rebuild?

i disabled all the lxde stuff and also openbox (all my own packages). and the result was the same.
find gives me 2 packages wich need wireless.h
find output/ -name configure* -exec grep -l wireless.h {} \;
output/build/kismet-2009-06-R1/configure.in
output/build/kismet-2009-06-R1/configure
output/build/libpcap-1.0.0/configure.in
output/build/libpcap-1.0.0/configure

i think libpcap has some errors when searching for linux/wireless.h
i attached my configcache and my libpcapconfiglog

You're right, I somehow missed that I had already compiled libpcap, so
it's configure step didn't rerun after I cleared the config cache.

I've added a fix to git (28ccc22ffd3) for this based on how it is fixed
in libpcap git. Could you give it a try to see if it fixes your problem?
