Hi @gpram,

As you are installing from source, see requirements in README file: [https://github.com/mendersoftware/mender#requirements](https://github.com/mendersoftware/mender#requirements)

If you are using a Debian based distribution, you need to install `liblzma-dev` package. You can also opt-out the dependency as it is explained in the README to not depend on such package.

Hello,

Please use text logs and avoid pictures when possible.

It seems like you are executing `github.com/mendersoftware/mender`, which should be a directory. I don’t know what is happening, I think there must be something strange in your golang setup.

Try with the following commands and post here the output.

```auto
go get -d github.com/mendersoftware/mender
cd ~/go/src/github.com/mendersoftware/mender/
make
./mender

```

**Note:** if you have a set GOPATH, then cd into `$GOPATH/src/github.com/mendersoftware/mender/` instead.

Okay, I think I know your output! The “#” symbols there are from the `go get` output, not your prompt as I originally thought.

Anyway, please try with `make` and copy us the logs.

The `gccgoflags` warning is very suspicious. Which version of GO are you using?

Post the output of `go version` and `go env`.

Hi,

Okey, I was finally able to reproduce your problem 🙂 So I don’t know exactly why the linker is failing, there must be something missing in the flags. But I can see that you are using `gcc-go` compiler instead of the most common `gc`. Any special reason for it?

If you don’t have a good reason, change to the standard compiler and your problem will be gone.

If using Ubuntu:

```auto
apt remove gccgo gccgo-go
apt autoremove
apt install golang

```

If you used the first approach (go get…), the mender binary will be in `~/go/bin/`

If you used the second approach (go get -d … + cd… + make), the binary will be in `~/go/src/github.com/mendersoftware/mender/`
