What version of go is needed?

[clach04]

Install instructions do not work for:

[pi@raspberrypi:~/go] 24s 2 $ go version
cat go version go1.7.4 linux/arm
[pi@raspberrypi:~/go] $ cat /etc/*elease*
PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
NAME="Raspbian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"
ID=raspbian
ID_LIKE=debian
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

Issuing:

go get -u github.com/dubyte/dir2opds

Results in:

package github.com/dubyte/dir2opds: cannot download, $GOPATH not set. For more details see: go help gopath

Setting GOPATH progresses a little further:

[pi@raspberrypi:~/go/t] 1 $ env GOPATH=`pwd` go get -u github.com/dubyte/dir2opds
# github.com/dubyte/dir2opds
src/github.com/dubyte/dir2opds/main.go:161: undefined: url.PathEscape

I did try building (same machine) but that was not successful. I tried out a recent version of Go for Windows, I was able to build via:

go build

I did not try the install option:

go version go1.14.2 windows/amd64

I'm not familiar with the Go ecosystem so I don't know how to progress/debug this further.

Hello clach04: you don't have to build dir2opds you can take the build for releases: https://github.com/dubyte/dir2opds/releases for the raspbian you could try dir2opds_v0.0.3_Linux-arm6.tar.gz

[dubyte]

If you want to build it I think the 1.7 is ok but you need to set your GOPATH env variable. usually is in $HOME/go so you can create a folder in $HOME called go

then in your $HOME/.bashrc add: export GOPATH="$HOME/go"

and that would be it.

[dubyte]

additionally you could install go 1.14.3 for raspbian using: https://golang.org/doc/install?download=go1.14.3.linux-amd64.tar.gz

@dubyte thanks for the suggestion, I'll check out newer go versions (note the link you have is for amd64 not ARM). I already had GOPATH set (see issue description, last test build).

I can't use prebuilt binaries for a couple of reasons:

• no CBZ support (see https://github.com/clach04/dir2opds/tree/comic)
• I also have another SBC with a different distro so a build would be needed there.

How was https://github.com/dubyte/dir2opds/releases/tag/v0.0.3 built, what version of Go/Rasbian?

I stumbled across https://llllllll.co/t/norns-on-raspberry-pi/14148/233 which indicated Go v1.10.3. was needed as a minimum for url.PathEscape

[clach04]

Update, found https://github.com/go-gitea/gitea/issues/3123#issuecomment-350401990 which indicates go v1.8 as minimum.

The think is that once that is compiled, you dont need go installed it will just work. is not like java or python. if you download a binary release it should work for in any raspberry with linux.

[dubyte]

if you want to create a pull request for the cbz I can merge it and create a new release.

[dubyte]

if you still have issue to compile it let me know i can help.

I am adding your suggestions in: https://github.com/dubyte/dir2opds/tree/release_0_4_0 So if you want to take a look and add more stuff please let me know.
