Building for Raspberry PI fail

[jaboto]

Hello,

I have been having some issues while getting chezmoi working on my Raspbian. After some issues already reported and successfully solved I ran into the following:

jaime@piBRU:~ $ go get -u github.com/twpayne/chezmoi`
[*many packaged found, downloaded and extracted* ]
go/pkg/mod/github.com/twpayne/[email protected]/cmd/completion.go:31:17: rootCmd.GenFishCompletion undefined (type *cobra.Command has no field or method GenFishCompletion)

GOGCCFLAGS="-fPIC -marm -pthread -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build181371003=/tmp/go-build -gno-record-gcc-switches"

As I was having some issues while getting go-github (see #issue-355 ) I have set the GO111MODULE as below:

jaime@piBRU:~ $ export | grep -i GO
declare -x GO111MODULE="on"
declare -x OLDPWD="/home/jaime/go"
declare -x PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/usr/local/go/bin"

Not sure if someone has run into this and how to solve it.

Thanks.

You need to build with Go 1.12 or later and GO111MODULE=on.

BTW the explanation for this line:

[twpayne]

(sorry hit wrong button)

The explanation for this line:

go/pkg/mod/github.com/twpayne/[email protected]/cmd/completion.go:31:17: rootCmd.GenFishCompletion undefined (type *cobra.Command has no field or method GenFishCompletion)

is:

1. chezmoi includes completions for the fish shell.
2. These completions are generated by github.com/spf13/cobra.
3. We're still waiting for fish completions to be merged into cobra (add fish completion support spf13/cobra#754).
4. In the meantime chezmoi is using a fork of spf13/cobra with the fish completion PR merged.
5. This fork is selected using this line in go.mod.

The above error likely comes from the go.mod file not being respected, e.g. by using an older version of Go or having Go modules disabled.

Hi @twpayne. Thanks for your quick response.

I am using Go version 1.12.9:

jaime@piBRU:~ $ go version
go version go1.12.9 linux/arm

Also, the GO111MODULE is on:

jaime@piBRU:~ $ export | grep -i GO
declare -x GO111MODULE="on"
declare -x OLDPWD="/home/jaime/go/pkg/mod/cache/download/github.com/twpayne/chezmoi/@v"
declare -x PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/games:/usr/games:/usr/local/go/bin"

So not sure why is not working.

It seems that despite the error the go/bin folder is created and chezmoi is there... Sorry to have bothered you and thanks for the quick support! :)

I have the same -- or at least a very similar -- issue.

I run a Raspberry Pi 3 Modell B Plus with the latest Raspbian Buster OS:

$ uname -a
Linux raspberrypi 4.19.66-v7+ #1253 SMP Thu Aug 15 11:49:46 BST 2019 armv7l GNU/Linux

I installed the latest Go version into /opt/go:

$ /opt/go/bin/go version
go version go1.13.1 linux/arm

When I try to install chezmoi, I get the following error:

$ GO111MODULE=on /opt/go/bin/go get -u github.com/twpayne/chezmoi
go: finding golang.org/x/sys latest
go: finding golang.org/x/net latest
go: finding golang.org/x/oauth2 latest
go: finding golang.org/x/crypto latest

/home/pi/go/pkg/mod/github.com/twpayne/[email protected]/cmd/completion.go:31:17: rootCmd.GenFishCompletion undefined (type *cobra.Command has no field or method GenFishCompletion)

In contrast to @jaboto, I do net get any executable:

$ tree -L 2 ~/go
/home/pi/go
├── pkg
│   ├── mod
│   └── sumdb
└── src
    ├── github.com
    ├── go.etcd.io
    ├── golang.org
    └── gopkg.in

Any idea how to build chezmoi on my Raspberry Pi?

[martinburger]

@jaboto Could you reopen this issue, please? As far as I can see, I am not allowed to do this.

[twpayne]

The reason for the build failure on your machine is the one described above. This is not a bug in chezmoi. Go on your machine is not respecting the replace lines in go.mod.

There are three options for you:

• Fix the Go installation on your machine so it respects go.mod.
• Petition for fish support to be merged in cobra (see add fish completion support spf13/cobra#754).
• Cherry pick this commit into your branch and build with that.

[tsaarni]

I guess there is no version of Go that respects replace lines in go.mod yet in combination with go get, so users will not be able to fix that. While replace line is needed and until Go has golang/go#31173 solved, I believe From source install method in the documentation will fail for users.

I ended up just cloning manually to work around this problem:

git clone --depth=1 https://github.com/twpayne/chezmoi.git
cd chezmoi/
go install
