Mac OS ARM - P2Pool 3.6.1 fails to run

[nullifiedtoast]

3.6.1 seems to build and start up just fine, however the longest I have gotten it to run for was 1 minute 16 seconds with the usually time of 5-7 seconds before it suddenly just stops with the exit code of failed. However there is absolutely nothing being shown in the logs about any errors. Everything looks normal and like 3.5 did and then it just abruptly stops.

Did you build it yourself, or use the release binary?

[nullifiedtoast]

I have tried both options, as well as trying to let Gupax update its bundled version and test that one. All three are doing the same thing with no reason given in the logs for the abrupt exit.

[SChernykh]

What's the version of your MacOS SDK? There is a known issue with macOS arm builds: monero-project/monero#8657 (comment)

But does P2Pool v3.5 release binary work fine?

[nullifiedtoast]

The SDK is 13.3 and the v3.5 does work just fine and is what I am still currently using.

[SChernykh]

So it probably means that the new way release binaries are built also uses new MacOS SDK, this is unfortunate. I'll have to revert to the previous build script for MacOS ARM binaries.

I shall await patiently for the next patch to be released and try to update from v3.5 then. Thank you for all your hardwork and dedication towards helping the monero community!

[SChernykh]

@nullifiedtoast It should be fixed in https://github.com/SChernykh/p2pool/releases/tag/v3.6.2

[nullifiedtoast]

I tried both the release binary and building from source again and they both still only run for about 20 seconds before the exit with the failed code. Once again checked the logs and it shows it running normal and then just abruptly stops again.

[nullifiedtoast]

Built from source runs for about 20-30 seconds and the release binary doesn't even want to start it immediately throws the failed exit code

[SChernykh]

@nullifiedtoast can you test the binary in the attachment? If this one doesn't work, then I don't know what changed since v3.5
p2pool.gz

[nullifiedtoast]

The version you just sent me started up and is running just like the v3.5 was with no issues

[SChernykh]

Good. So it has something to do with LTO (link-time optimization). Apple clang compiler has some bug somewhere in LTO. I'll update the v3.6.2 release with this binary.

[nullifiedtoast]

I am glad you were able to figure out the issue. Thank you again for the fast responses to get it fixed.

[nullifiedtoast]

Only thing I noticed about the version you just sent me was that my miners were not able to connect to the pool with it.

[SChernykh]

Check your firewall settings (path to the binary, port numbers). You probably need to approve the new binary.

[nullifiedtoast]

I needed to move the binary into the folder with the rest of p2pool files. That was my mistake all is working correctly.
