Could it be that you're hitting the issue that @junjiemao1 mentionned here? If so, upgrading your binutils to 2.27 or higher should solve this.

Or you can also try to revert this commit on your tree as an experiment (we do not recommend to remove it permanently, this is just for testing)

[chasinglulu]

thank you!

[gvancuts]

FYI, there was (another?) problem with the relocation feature for which a patch just got merged - see #1120

[gvancuts]

Hi @chasinglulu , have you been able to resolve your problem? If so, can you please close this issue? Thanks!

[gvancuts]

@chasinglulu @kiendinh can you confirm what exactly fixed the issue for you?

I would like to know if we need to amend our "Getting Started Guide" with additional instructions (or a note): https://projectacrn.github.io/latest/getting-started/apl-nuc.html#build-acrn-from-source

@gvancuts, I used to checkout the tag which was known to compile (ie, acrn-2018w35.4-140000p). However today the latest master branch was built successfully on Ubuntu 16.04 with binutils 2.26. Some recent changes may have fixed the issue.

Thanks Kien. No need to modify the existing doc then!

I'm re-opening this issue as using the latest binutils (2.26) version from the Ubuntu 16.04 repo does not work for me. Manually upgrading to 2.27 (or possibly higher) is required as far as I can tell.

Closing this issue as upgrading binutils to 2.27 solves the build issue on Ubuntu 16.04
