Ignore it, it’s not important for building a bootstrap compiler.

I was not clear in my initial issue... I'm using the bootstrap compiler to build go1.8.3 |
|
Trying to understand what you mean here... Are you just suggesting I download the 1.8.x binary instead of trying to build it from source?
I have read, and followed that documentation, but that is for building go1.4, which I have already done successfully. I will try running make.bash in the 1.8.3 checkout, and post the results of that, but that's not what the documentation says to do. |
|
Okay, that wasn't very clear. Now it's clear. No need to mention go1.4-bootstrap: you are seeing test failures when running |
|
Running make.bash in the 1.8.3 checkout succeeded. Though, I think this is just because it doesn't run the tests. |

Can you try running |
|
Yes, I have tried that, and the test still fails. |

So this is also failing on the current go release. Nice, thanks for the report. Labelling this as NeedsInvestigation. |

If you are on linux/amd64: yes. There's no need to compile the toolchain by yourself. Actually you should download the go1.9.1 binary, there's no reason to use an old version. |
I need to build Go from source for my use-case, and specifically version 1.8.3. This is for a project, in which 1.8.3 has been extensively tested, and verified to work properly. |
Then it's fine to build from source. But even then, you don't need go1.4. You can use a go1.9.1 binary to bootstrap. |
|
I don't want to bootstrap with an unverifiable, and currently (in my case) non-reproducible binary. I was doing my best to avoid this discussion, however. :) |
|
This is almost certainly #17206, which is fixed in the 1.9 release. The fix was to simply ignore the error, as it is apparently unavoidable on certain systems, so for 1.8.3 that is what you should do. Closing because we aren't going to fix this in 1.8.3. |
|
No problem. Let's keep this thread about the go1.9.1 syscall test failure you reported, then. |
|
Sorry, I missed that this was apparently seen in 1.9.1. I don't see how that is possible, but I'll reopen. Please tell us precisely what you do when building with 1.9.1, and precisely what happened. Thanks. |

Here's a pretty large excerpt of the results from running all.bash in the go1.9.1 checkout. |
|
This is top few lines after running ./all.bash: |
|
Thanks. So on 1.9.1 you are getting different errors. I guess there may be more places in syscall/exec_linux_test.go where we need to check for "operation not permitted". Are you running this inside as container, as root? If so you are likely running into #21379, which has been fixed for the future 1.10 release. |
Yes, I am running it in a docker container, as root. My apologies for not mentioning this sooner. |

Thanks. I'm inclined to close this a dup of number #21379. It doesn't indicate any problem with your build, just a problem with the test. |
Yes, I think that's right. Let me try running make.all in master, which should work. |
|
All tests passed on master 9d3d370. Thanks for the help. |
