Native installation fails on Pi 3 B #29

On installing this from the manual using go get -u -v github.com/schollz/find3-cli-scanner, I get the following error.

$ go get -u -v github.com/schollz/find3-cli-scanner

github.com/google/gopacket/pcap # github.com/google/gopacket/pcap
../github.com/google/gopacket/pcap/pcap_unix.go:373:16: type [1073741824]_Ctype_int larger than address space

../github.com/google/gopacket/pcap/pcap_unix.go:619:18: type [1073741824]_Ctype_int too large

I initially thought this was an error from the gopacket library, so I installed it separately using go get github.com/google/gopacket, and that worked without any error. So I have to believe this happens only when using gopacket with this cli-scanner.

I installed go by downloading tar for ARMv6l and extracting it to /usr/local as given here: https://golang.org/doc/install

Maybe try to install using xgo.

./xgo -ldflags='-linkmode external -extldflags "-static -s -w"' --deps=http://www.tcpdump.org/release/libpcap-1.8.1.tar.gz --depsargs=--with-pcap=linux --targets=linux/arm-6 github.com/schollz/find3-cli-scanner

First build xgo wrapper from https://github.com/jekkos/xgo/

zeroby0 commented 5 years ago

Hey @jekkos ! Thanks for commenting :)

It fails, unfortunately. Here's the output.

$ xgo -ldflags='-linkmode external -extldflags "-static -s -w"' --deps=http://www.tcpdump.org/release/libpcap-1.8.1.tar.gz --depsargs=--with-pcap=linux --targets=linux/arm-6 github.com/schollz/find3-cli-scanner

I ran it once again, to check if it needs to pull the first two. Errored again.

I found this online https://github.com/containers/buildah/issues/475#issuecomment-382069330 . I'll check if it works.

jekkos commented 5 years ago

You could also try xgo from this repo ykyuen/xgo instead

jekkos commented 5 years ago

Or use my python script together with tcpdump to do the scanning.. (see other issue here in the repo)

jekkos commented 5 years ago

My repo also has a script to run it with airodump-ng. This might give you more control on how you want to setup the monitor mode itself.

zeroby0 commented 5 years ago

Yeah, that's better. I ended up forking schollz/wifiscan and making some small changes.

Thanks a lot @jekkos , this comment of yours led me to my implementation :)
