cross compilations techniques compile error about go-dht HOT 1 CLOSED

Hi @volker-raschek! Sorry, for delayed response.

You should remember, that since DHT library partially written in C (and your native system has no ARM7 architecture), and you employ "cross compilation techniques", so you should have on your system special cross c-compiler installed. The name of c-compiler for Debian/Ubuntu system will be arm-linux-gnueabi-gcc, for Arch Linux arm-linux-gnueabihf-gcc.

So, once you have this c-compiler, you must modify your compilation call accordingly:

• for Debian/Ubuntu: CC=arm-linux-gnueabi-gcc CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7|6 go build
• for Arch Linux: CC=arm-linux-gnueabihf-gcc CGO_ENABLED=1 GOOS=linux GOARCH=arm GOARM=7|6 go build

Note: you should select ARM version 6 or 7. Regular Raspberry PI ordinary has 6.

I have one on my Arch Linux notebook where i'm doing all the development (and cross compilation works good), and as I remember arch ecosystem has this compiler only in AUR repository, so you should install it from here:
https://aur.archlinux.org/packages/arm-linux-gnueabihf-gcc/

I think the hardest part here is installing a с-compiler, so try and let me know if you still need help.
