Hi,

Currently building Mender-3.2.1 for OpenWrt-21.02 x64, but can’t get past this issue.

Host:  
Debian 10  
Musl 8.4  
Gpio 2.58.3

```auto

```

Also, would grub2 need to be patched for Mender to work properly? I see patches for uboot.

have you tried installing the liblzma-dev package on the build machine?

Take a look at the below, it may be helpful, you may need to set some golang env vars. Sorry I don’t know much about golang.

> Then GOARCH=arm is needed. I also think that you have passed the wrong sysroot as argument, host instead of target. It should be something like this: make CGO\_CFLAGS="--sysroot=$SDKTARGETSYSROOT -I${LIBLZMA\_INSTALL\_PATH}/include" CGO\_LDFLAGS="--sysroot=$SDKTARGETSYSROOT -L${LIBLZMA\_INSTALL\_PATH}/lib" CGO\_ENABLED=1 GOOS=linux GOARCH=arm

Thanks, turns out that even though the host had the libraries they weren’t enabled in OpenWRT.

I’m using the build script by [rossbcan](https://hub.mender.io/u/rossbcan), I’m not sure what to put in

> export UBOOT\_DIR:=$(BUILD\_DIR)/

As u-boot isn’t being used and grub2 doesn’t seem to live in the build\_dir.

Sorry, I don’t know the answer to that one.
