GCC is up to date: gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.9)

Any ideas?

[jasonbcox]

GCC 5.4 is the highest available in the Ubuntu 16.04 PPAs, but it's not the latest version. I recommend installing GCC 7.1+. You also have two alternative options:

1. Fix the bug preventing GCC 5.4 from building and submit a PR (example: https://reviews.bitcoinabc.org/D1113) We'd greatly appreciate this, as I'm sure you're not the only one to run into this issue.
2. Build using CMake. There are some restrictions since CMake builds are still in progress, but you should be able to build a binary at the least.

[axelay]

I upgraded to gcc version 7.1.0 (Ubuntu 7.1.0-10ubuntu1~16.04.york0)
but I still have the same error... Any other ideas?

[jasonbcox]

There should be more info about the error above this failure message. Can you provide that?

[axelay]

Not sure if that helps but here is the complete output for make:

[schancel]

You need to regenerate your makefiles: ./autogen.sh && ./configure

[axelay]

Nope - done that already and it gives me the same result.
Anybody else got these issues or just me?

[schancel]

@axelay I've had the issue. It started happening immediately after some cleanup of the seeder code. Cleaning my build dir, and rerunning the commands I listed above fixed it.

[axelay]

I have now successfully compiled it and it's running - I cloned the repository again in the end just to make sure I had nothing left that could mess things up.
Thanks for the help @schancel & @jasonbcox

How to solve it? Do you remember? Because I've had this problem, too.
