I am trying to install MCUMgr on MACos. Here is a link for mcumgr: https://docs.zephyrproject.org/latest/services/device_mgmt/mcumgr.html
I install the Go Programming Language and enter this command:
go install github.com/apache/mynewt-mcumgr-cli/mcumgr#latest
Upon doing this I get the following error:
go/pkg/mod/golang.org/x/sys#v0.0.0-20200223170610-d5e6a3e2c0ae/unix/zsyscall_darwin_amd64.go:28:3: //go:linkname must refer to declared function or variable
I then googled and found the following from stackoverflow: Go 1.18 build error on Mac: "unix/syscall_darwin.1_13.go:25:3: //go:linkname must refer to declared function or variable"
This gives me the following error:
go: golang.org/x/sys: unrecognized import path "golang.org/x": parse https://golang.org/x?go-get=1: no go-import meta tags ()
I am stuck right now on how to install MCUMgr for MACos and wondering if someone has previously had the same issues?
I used go 1.17 instead and used:
go get github.com/apache/mynewt-mcumgr-cli/mcumgr
Then into the bin folder where it is installed use sudo ./mcumgr to run.

Trying to follow the installation guide here and most of the process is working. I'm having an issue with building it however.
When trying to build I'm getting this message:
C:...\gameboy.live>go build -o gbdotlive main.go
......\go\pkg\mod\fyne.io\fyne#v1.0.1\driver\gl\gl.go:20:2: missing go.sum entry for module providing package github.com/goki/freetype (imported by fyne.io/fyne/driver/gl); to add:
go get fyne.io/fyne/driver/gl#v1.0.1
Running the suggested command however raises another prompt:
C:...\gameboy.live>go get fyne.io/driver/gl#v1.0.1
go get fyne.io/driver/gl#v1.0.1: unrecognized import path "fyne.io/driver/gl": reading https://fyne.io/driver/gl?go-get=1: 404 Not Found
I've tried going for the version 1.4.3 driver too which raises a different error:
C:...\gameboy.live>go get fyne.io/fyne/gl#v1.4.3
go get: module fyne.io/fyne#v1.4.3 found, but does not contain package fyne.io/fyne/gl
Anybody familiar with this issue? FYI I'm on Windows and have MinGw installed already.
Just run go mod tidy before exec go build -o gbdotlive main.go.Have a try.
A Go language tutorial uses the "quote" package to get familiar quotes. When I give the command "go get -v rsc.io/quote", I get the message
code in directory.../github/hello/src/rsc.io/quote/v3 expects import "rsc.io/quote"
So I went there and looked at the code. It has an import statement:
import "rsc.io/quote/v3"
So I thought maybe I had the wrong version of quote. Accordingly, I tried "go get -v rsc.io/quite/v3" THis produces the message:
code in directory .../rsc.io/quote/v3 expects import "rsc.io/quote."
This seems circular: asking without a version number produces a requirement for a versioned package, but trying to get a versioned package produces a requirement without a version number.
If you continue the tutorial to the end you will see that the addition of a go module, and the subsequent initialisation, will resolve your issue. The .mod file will pull in the required dependencies.
Can you try
go get -v rsc.io/quote
get "rsc.io/quote": found meta tag get.metaImport{Prefix:"rsc.io/quote", VCS:"git", RepoRoot:"https://github.com/rsc/quote"} at //rsc.io/quote?go-get=1

get "rsc.io/sampler": found meta tag get.metaImport{Prefix:"rsc.io/sampler", VCS:"git", RepoRoot:"https://github.com/rsc/sampler"} at //rsc.io/sampler?go-get=1

More about go get vs go install. What is the difference between go get and go install?
Can you please check your GO env path settings:
export GOPATH=$HOME/github/<your_workspace_name>
export GOBIN=$GOPATH/bin
export GOROOT=/usr/local/go
export PATH=$PATH:/usr/local/bin:/usr/local/go/bin:$GOPATH/bin
Here is a good source for setting up workspace:
https://golang.org/doc/gopath_code.html
As #MartinBennett mentioned, it's already mentioned in the tutorial but may be not so clear.
Once you add import "rsc.io/quote" in your hello.go file, you will need to run these commands in your terminal:
1-
go mod init hello
2-
go run hello.go
I am trying to add reflection to my working Go-based gRPC. I am getting an error when I try to fetch the reflection package:
$ GO111MODULE=on go get google.golang.org/grpc/reflection
go: github.com/google/go-github#v0.0.0-20190119011113-56cb1dd99043: go.mod has post-v0 module path "github.com/google/go-github/v21" at revision 56cb1dd99043
go: error loading module requirements
I can't find any reference to "go-github/v21" anywhere in my source, or in any of the packages in my GOPATH.
I also can't figure out what this error message means.
I am using Go version go1.11.5.
Thanks.
I tried to use gotk3 for creating desktop application. I follow the instruction in gotk3 wiki and this installing-on-linux wiki to install it. But then I get this error while executing go get -v:
gcc errors for preamble:
In file included from ../../gotk3/gotk3/gdk/gdk_since_3_22.go:23:0:
./gdk_since_3_22.go.h:22:8: error: unknown type name 'GdkMonitor'
static GdkMonitor *
^
I've tried to delete the gotk3 directory, and then trying to go get -v again, but still, it didn't work.
I also checked the GTK version that installed in my Ubuntu 16.04 using apt-cache policy libgtk2.0-0 libgtk-3-0 | grep Installed. And it shows this:
Installed: 2.24.30-1ubuntu1.16.04.2
Installed: 3.18.9-1ubuntu3.3
What did I do wrong? Thanks
GdkMonitor was introduced in GTK+ 3.22. Your version is 3.18.
go get -tags gtk_3_18 github.com/gotk3/gotk3/gtk at the very beginning of building (see here NOTE section) should fix things
I had some issues with gopath configuration. I was able to resolve the go path issue. But getting this error...
[root#localhost mysqlbeat]# go get github.com/adibendahan/mysqlbeat
# github.com/adibendahan/mysqlbeat/beater
/root/go/src/src/github.com/adibendahan/mysqlbeat/beater/mysqlbeat.go:289:7: b.Events undefined (type *beat.Beat has no field or method Events)

/root/go/src/src/github.com/adibendahan/mysqlbeat/beater/mysqlbeat.go:326:5: b.Events undefined (type *beat.Beat has no field or method Events)
How do I correctly install go package along with all it's dependencies?
Update:
I downloaded the package and tried to run it.Different error this time...
[root#localhost mysqlbeat]# make
go build
can't load package: /root/go/src/src/github.com/adibendahan/mysqlbeat/main.go:8:2: non-standard import "github.com/adibendahan/mysqlbeat/beater" in standard package "src/github.com/adibendahan/mysqlbeat"
make: *** [build] Error 1
Check out the How to Build section on README.md on mysqlbeat.
mysqlbeat uses Glide for dependency management. Check this for installing glide.
After installing Glide, clone the mysqlbeat repository and run:
$ glide update --no-recursive
$ make
If you still want to import this repository by go get, clone the repo and then run go get ./... from its root directory.
