Raspberry Pi 4 32 bit compile problems

[ScallyBag]

Hi,

whenever I try to compile your engine I get these errors:

Al@RPi4-SSD:~/go $ go get -u github.com/amanjpro/zahak/zahak

github.com/amanjpro/zahak/engine

src/github.com/amanjpro/zahak/engine/cache.go:32:27: syntax error: unexpected b1111111111111111111111111111 after top level declaration src/github.com/amanjpro/zahak/engine/cache.go:33:27: syntax error: unexpected b1111111111111111 after top level declaration src/github.com/amanjpro/zahak/engine/cache.go:34:28: syntax error: unexpected b1111111 after top level declaration src/github.com/amanjpro/zahak/engine/cache.go:35:27: syntax error: unexpected b111 after top level declaration src/github.com/amanjpro/zahak/engine/cache.go:36:26: syntax error: unexpected b1111111111 after top level declaration

Also I’ve tried your provided binaries for 32bit and 64bit for v5 and v6 but neither run on Raspberry Pi 4, which is completely up to date running Raspbian OS 32bit.

Thanks,

Al.

I have never tried using go get command to compile, I use make build for building, can you try this instead:

$ git clone https://github.com/amanjpro/zahak.git
$ cd zahak
$ make build

Also, I don't have RaspberryPi 4, or any ARM 64 for that matter, I have once tried running it on a friend's computer and it worked.

I am currently successfully running versions 5 and 6 on RaspberryPi 3 - 32bit... will look into this

Thanks for having interest in Zahak

Also, what version of golang are you using?

Hi,

Thanks for the quick reply, I had already tried GitHub but tried the other way because other GO engines work that way too. However here is what you asked:

Also, here’s what I get when I try your binaries:

============

I’m using a Raspberry Pi4 running 32 bit Raspbian OS that is fully up to date with the latest software. I’ve compiled over 100 engines for the RPi for Picochess using lots of different Compilers.

Thanks for your time.

Al.

Hi,

Al@RPi4-SSD:~ $ go version go version go1.10.1 linux/arm

Al.

[amanjpro]

Oh, this is very old version of GoLang, my engine has been tested with 1.16 and above

As for the version 5, it actually works if you send ucinewgame before sending go infinite, so please try that... And I am currently trying to fix the version 6.0 issue, and will do a hotfix right after

[amanjpro]

Can you try this hotfix: https://github.com/amanjpro/zahak/releases/tag/6.1

[amanjpro]

Actually try that one instead: https://github.com/amanjpro/zahak/releases/tag/6.2

[ScallyBag]

Hi,

Your older 32 bit v5 does run, I forgot the ucinewgame which I normally try on a failure. v6 does not run as you’re aware.

I quickly tried your v6.2 but the makefile refers to your original version not the fixes.

I’m away in Scotland now, so will try any fixes and try to upgrade GO when I return next week.

thanks for your efforts,

Al aka Scally on the forums.

[amanjpro]

Don't try make, just download this binary for raspberrypi 32bit: https://github.com/amanjpro/zahak/releases/download/6.2/zahak-linux-arm32-6.2

[ScallyBag]

Hi,

yes that binary works thanks.

I’ve also update to go v1.17.1

Al.

[amanjpro]

Cool, thanks for confirmation. I'll close the issue :)

[ScallyBag]

Thanks again.

go v1.17.1 didn’t work for me, however go 1.14.4 works, I can run Makefile and the go get command, both provide working binaries.

Al.

[amanjpro]

I have never tried Go 1.17, will try that later

[amanjpro]

Out of curiosity, are you running it on a DGT Pi?

[ScallyBag]

I will be, I’m just home after a week away, so will be trying your engine tomorrow on my DGT Pi.

Al.

Cool, I'm really interested in your experience, as I also want to get a DGT Pi + DGT board setup :)

Hi Amanj,

I have emailed you on your email address given on your website. I think I spelt your name wrong, apologies.
