Current not implemented on linux/arm

[azman0101]

Hello,

I've installed Golang on a Linux VM

sudo GOOS=linux GOARCH=arm ./make.bash --no-clean

Cross-complied with this command:

make -j8 GOARCH=arm CC=/usr/bin/arm-linux-gnueabihf-gcc-ar-4.8 CGO_ENABLE=1

And then, after following the tutoriel for encryptedfs creation:

You have a typo in your compilation command, if you check INTERLOCK README file the command uses CGO_ENABLED and not CGO_ENABLE.

Let me know if this is the issue so that I can close the ticket.

Thanks!

Then I've build Go like this:

Your cross compiling environment has some issues, it might be not modern enough or not configured correctly. Rather than debugging those I suggest you build INTERLOCK directly on the target (which I am assuming it is the USB armory). If you want to try and fix your cross compiling environment you can try and set it up as suggested at https://github.com/inversepath/usbarmory/wiki/Preparing-a-bootable-microSD-image.

Keep in mind that if you are building for a non-ARM host (like an x86 machine) then cross compiling is not necessary and you can just use make.

I personally find it easier to just have native arm Go and compile INTERLOCK on my USB armory directly.

Thanks for your help. As you mentioned before, my cross compiling environment has some issues.
