Macbook Pro mid 2009 has trouble to start up the server #429

Closed heunglee closed 6 years ago

heunglee commented 6 years ago

Macbook Pro mid 2009, 2.53 GHz Intel Core Duo Had fresh install.

Command executed: grin server -m run

terminated with the following stdout. Dec 03 09:42:16.350 WARN P2P server started on 0.0.0.0:13414 Dec 03 09:42:16.352 WARN Grin server started. Illegal instruction: 4

Can you post the output of RUST_BACKTRACE=1 grin server -m run?

heunglee commented 6 years ago

I tried to start the server with RUST_BACKTRACE=1 option. But no error was displayed in stdout and log file. It just died silently. Only illegal instruction: 4. I googled the error message in stackoverflow and found the following Q and A. https://stackoverflow.com/questions/14268887/what-is-the-illegal-instruction-4-error-and-why-does-mmacosx-version-min-10

As mentioned above, my macbook pro is a model of mid 2009 and upgraded to mac os 10.12.x. My macbook pro is however not allowed to upgrade to High Sierra. The CPU is Intel Core Duo which might be x86 compatible based on an online source. But the cuckoo cycle miner with grin compilation features seems not compatible with the CPU. I did not try the internal miner.

In my opinion, the error just resulted from incompatible hardware for binary of cuckoo cycle miner.

Apple does not allow Macbook pro mid 2009 to upgrade to latest version of OS (High Sierra). So the model is fading away! or already faded out?. Under the circumstance, it is not good idea grin dev needs take efforts on this issue. It seems to me Macbook pro mid 2009 does not fulfill the hardware requirement of grin. Just my thought...

No worries. Can you check you're on the latest code with git pull and the testnet1 branch? Then disable the miner in gein.toml and try again. Maybe check build.md for any extras how to avoid mining plugins. Mining plugins will be for GPU and not for Intel CPU processors soon anyway, so don't worry about mining. You can participate in building up grin anyway! ;)

The server starts and syncs without miner. And having other issues during syncing. So my server has not been able to sync completely yet. But I kind of verified that macbook pro mid 2009 is limited to run the server node fully so far :-)

This issue was not reproduced in iMac late 2013. So this issue was very specific to old mackbook pro like mid 2009. So it is recommended to avoid macbook pro late 2009 for grin servers.
