Hello everybody. I have a minor problem with the cross compilation of Mender-client. Everything works great but when I run “mender -version” the shown version is unknown. (So in mender server the version of Mender client for every device is unknown too). Perhaps I am missing some parameter that has to be given when compailing. Any body has faced this? best regards. ---

Hi @MarekBelisko, thanks for your response. I compile it with a script: LIBLZMA\_INSTALL\_PATH="$(pwd)/install" cd $GOPATH if [cpu == "armv8"]; then GOARCH="arm64" CGO\_CFLAGS="-mtune=cortex-a53 -I{LIBLZMA\_INSTALL\_PATH}/include" CGO\_LDFLAGS="-L${LIBLZMA\_INSTALL\_PATH}/lib" else echo “Error: unsupported processor type: $cpu” exit 1 fi printf -v ARCH “%sv%s” $GOARCH echo “Building binary for $ARCH architecture…” go clean $package env CGO\_ENABLED=1 CC=$CC GOOS=$GOOS GOARCH=$GOARCH CGO\_CFLAGS="$CGO\_CFLAGS" CGO\_LDFLAGS="$CGO\_LDFLAGS" go build -o $output\_file $package ---

@MarekBelisko I based my script on [https://github.com/mendersoftware/mender-crossbuild/blob/master/go-executable-build.sh](https://github.com/mendersoftware/mender-crossbuild/blob/master/go-executable-build.sh) , but the version in the bianry is missing. Nevertheless the binary is well compiled and works fine in my board. ---

@mirzak how can I open a pull request to add the needed changes to add the version when compiling with go-executable-build.sh? I have tried with my github user but (as expected) I do not have permission for that. ---
