SK-AM64B: Buildroot error while building

Hi Amey,
did you perform the below command that is part of the current FAQ...

$ git checkout -b am6x-dev 9b25246e9b

...or did you use some other commit?

Regards, Andreas

Hello Andreas

I had used same commit. But just to be sure. I started again with clean chekout and followed all steps from FAQ.

But even then I am getting following error

Amey,

to me this looks like you have a generic network issue. There are failures early on when cloning the repos. Do you need a proxy config maybe? Can you discuss the failures with your IT team?

Without successful clone of the repo the following steps in build will not work I assume.

Regards, Frank

Hello Frank

The repo was successfully cloned. And the make command ran for around 20-25mins (building various modules) before reaching this error. In between during the build it also downloads many packages successfully

Thanks

Amey

Hi Amey,

let me try this build today on my end and report back.

Regards, Andreas

Hello Andreas

Thanks for trying it out on your machine. I am running Ubuntu 23.10 on VMWare

Here is the screenshot of disk usage

The total size of your folder is around 29G. All this is downloaded & built during the build process?

As suggested, I will try it natively installing on the machine

Regards

Amey

Buildroot is usually pretty good being quite "tolerant" as to the build environment (unlike Yocto, I found). Still, you may also want to try Ubuntu 22.04 if your issues persist.

As for the total size of the folder after you build it yourself it will probably be larger than 29G because I used the BR2_CCACHE=y option to build locally, not all intermediate files were generated. On a related note I'd highly recommend using this option for your builds, as it will dramatically speed up newly setup builds. Same for the keeping a copy of the download folder and re-using it / sharing it between your different build environments.

Regards, Andreas

Thanks Andreas. 

I had used the option BR2_CCACHE=y before running make. I believe that option is "Use Compiler Cache", that is correct?

Thanks for letting me know that copy of download folder can be reused

Regards

Amey

yes that is correct.

Hello Andreas

I installed Ubuntu 22.04.4 on VMware and started a clean build. I was able to successfully build the entire source code.

The total size of folder after build is 29G same as your screenshot above. 

Thanks

Amey
