Making Mender client binary file
Hi @gpram,
As you are installing from source, see requirements in README file: 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.
when am execute this command
go get github.com/mendersoftware/mender
still am getting error some differenet… pls check image attachement
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.
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.
thank u but when execute make command am getting error see bellow
go build -ldflags "-X main.Version=1.7.1"
go build: when using gccgo toolchain, please pass linker flags using -gccgoflags, not -ldflags

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:
apt remove gccgo gccgo-go
apt autoremove
apt install golang

thank you bro your rocking…thank u so much i removed gccgo and gccgo-go
then i installed golang …its working now tthank you
After compilation has finished, the Mender binary is located at where …
may i know where i have to find Mender binary file
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/
i found out mender file in /go/src/github.com/mendersoftware/mender
is it mender file is binary file ?
That is correct!
ok thank you for supporting me … keep in touch bro …
