Installation issue: undefined: QueryBuilder about objectbox-go HOT 12 CLOSED

Hmm, just checked on a blank golang:1.13.3 docker image and it worked for me :/

I see you're using the manual installation for a project without go modules, i.e. you're installing objectbox-go globally into your $GOPATH. Is that what you intended? If so, have you had objectbox-go installed before so maybe there's some conflict with an old version?

Maybe you could try removing the installed version like in the script below. This assumes a global installation, i.e. when you're not using go-modules.

rm -r $GOPATH/src/github.com/objectbox/objectbox-go

If you're using go modules, you should just import the package using import "github.com/objectbox/objectbox-go/objectbox". You still need to install the objectbox-c binary library for the program to work.

Ok, thanks. Switched to using go-modules.

Here is what I see now:

go build ./src/services/calculation/
cannot find module for path github.com/objectbox/objectbox-go/internal/generator

cat go.mod

cannot find module for path github.com/objectbox/objectbox-go/internal/generator

Are you, by any chance, importing .../internal/generator directly, it's something used by the generator command-line application and not intended to be used by the library users. That's why it's in internal and go prevents a direct import.

Also, I don't understand how your /mnt/c/DEV/projects/go/src/github.com/objectbox/ ended up looking how it does. Maybe you have executed the download.sh when inside that directory? Because it looks like the temporary dir created by the download.sh/install.sh, not like go package source (this repository). Removing /mnt/c/DEV/projects/go/src/github.com/objectbox/ would be probably a good idea - Go is probably picking it up as a module installed globally but the directory's content isn't correct.

I hope that helps

from go help gopath:

Internal Directories

Code in or below a directory named "internal" is importable only
by code in the directory tree rooted at the parent of "internal"

the model.go file is rooted in:
github.com/objectbox/[email protected]/objectbox/model.go

but the generator package is rooted in:

github.com/objectbox/objectbox-go/internal/generator

So if I read the help file correctly, model cannot import generator, hence the error message.

Am I correct?

from objectbox-go.

I can't see anything wrong with your go env 👍

/home/bob/go/src/bitbucket.org/rerosum/algotrader

With go modules, your project should not be in the $GOPATH, IIRC I've had problems with such projects before. Not sure if it's the cause here, but could you try moving your project out of GOPATH, i.e. out of /home/bob/go, at least temporarily. Maybe also try searching for all directories named objectbox to make sure there are no stray ones, like find ~ -type d -name objectbox

I can't imagine how the internal could be the culprit, in that case, the code wouldn't work for anyone, ever, not even in the library itself.

Code in or below a directory named "internal" is importable only by code in the directory tree rooted at the parent of "internal"

"The parent of "internal"" => github.com/objectbox/objectbox-go
"the directory tree rooted" => anything below objectbox-go, i.e. also objectbox-go/objectbox/model.go

Just an idea: if you're using "objectbox" as a package (directory) name inside your project, it might be messing with go package resolution as well (seen it in the past).

If nothing else helps, maybe trying to narrow down the scope would help to find the problem, e.g. by trying to include objectbox in a minimal example project you could share. If that still doesn't work for you, and the example works in a docker image, then we at least know it's somehow related to the environment.

from objectbox-go.

Also, there was an issue #16 - giving the same error message - turned out to be due to cross-compilation. You aren't trying to do that, are you?

Firstly, thank you for helping me work through my issue. I'm sure the problem is on my side, so I took your advice and started from a clean test project located outside of the GOPATH. Here is what I see when running the installer:

I have to say I'm baffled why my environment is behaving differently than yours.

I'll try any ideas you might have, thank you.

from objectbox-go.

Looks like I figured it out. Here is what was wrong with my environment:

I didn't have gcc installed and w/o it I was missing the *.h files typically found in the ../include system folder and which are needed for the imports of objectbox.h. This prevented querybuilder.go from compiling which is needed by condition.go.

I'm all set for now, thanks for all the help!

from objectbox-go.

I'm glad to hear that you've figured it out. It's a pity the error is so cryptic/unrelated to the actual cause :/ I'll update the docs with the findings. Thanks for the feedback.

from objectbox-go.

I didn't have gcc installed

@vaind can our setup script check for that and give advice how to install it?
