Gomobile can not build Hypnic game

[TechComSpot]

Hi, @Noofbiz.

I am in Hypnic directory and did gomobile build but got errors:

Can you advice please ?

[Noofbiz]

Yeah you actually go into the androidglue folder then run 'gomobile bind --tags=mobilebind' and it'll generate an aar file that you then put into the android/androidglue folder. Then you can open android as a project in Android studio and build it as an apk there. I will put that in the readme when I get to it lol

@Noofbiz thank you.
But why gomobile build is not working here anymore?
If I am not wrong it worked before the last time I study hypnic.
Is it something related to engo engine?

[Noofbiz]

Actually, those two errors look like you're using old versions of oto and gl. In go 11 you can no longer not initialize jni objects, you have to set them explicitly to zero, so oto had to be updated for that. Then gomobile changed the teximage2d signature, so gl had to be fixed. Running go get -u github.com/Noofbiz/hypnic should fix the errors.

Hi, @Noofbiz.

Thank you for response. I did like you said go get -u github.com/Noofbiz/hypnic but got next error:

Can you help, please.

[Noofbiz]

try going into the hypnic directory and doing git fetch or git checkout master

[TechComSpot]

Hi, @Noofbiz.
I handled those errors but when came to androidglue directory and execute gomobile bind --tags=mobilebind got another errors:

Also when I try running hypnic this time I got:
go run main.go

Do you have the alsa library installed? Try 'sudo apt install libasound2-dev'

[TechComSpot]

@Noofbiz thank you for helping me.
I tried as you said with libasound and terminal said:

Then I tried again with gomobile:

:(
Any suggestions?

[Noofbiz]

Looks like you have more than one version of go installed and it's trying to build both. Try uninstalling and reinstalling go. Just delete usr/local/go and then reinstall go.

[TechComSpot]

@Noofbiz I reinstalled golang from binary installation to the systems installation.
Error gone but another one shows up:

[Noofbiz]

I'm not sure. It says there's a file first.go that uses package main. Any file with the package main needs to have the tag //+build !mobilebind followed by a blank line at the top of the file. If you want to use it for Android as well you'll need a separate file with the package hypnic and //+build mobilebind

[TechComSpot]

Hi, @Noofbiz
I almost handle all appeared errors but in the end got this:

But in the platform directory I have this:

[Noofbiz]

Did you run 'gomobile init'?

[TechComSpot]

Yeap, just before executing this one.

[TechComSpot]

Hi, @Noofbiz
:((Got one more error:
