sdauth, what intel (core 2) chip do you have?

| Code: | -- Performing Test _maes_cxx

-- Setting CXX flag -maes

-- Setting C flag -maes

-- AES support explicitly disabled |
It does try and see if it's available and claims success, but does honor turning off AES.
I have a feeling the tests, are being done with march=native vs march=core2 and thus they succeed.
Edit to add: I looked to see what debian was doing and they pass these

You might set aes like the above and see if it improves things.
Cmake does need to pass -DNO_AES as a define, because it's used inside some of the crypto code to decide what to generate.

It's a P8600 clocked at 2.4Ghz, old stuff

Indeed.

For now, without -DNO_AES, it works. (although, slow af since the blockhain is stored on an old hdd.. maybe it will trigger something.. still sync'ing currently, we'll see if it crashed tomorrow !)
So, debian is using -DNO_AES=ON... Interesting, for all their x86_64 build I assume ? Anyway, it makes sense to add it anyway since after all my P8600 doesn't have aes instruction. |

Definitely no AES instruction on that chip.
I did read a comment in that it seems cmake is kind of stupid and if it sees x86_64 it makes lots of assumptions (like aes  )
this was noticed by people building on the x86 pc for the arm arch.
And it will be slow running on that cpu, as the crypto stuff now has to use routines instead of the aes call.

hope it's not THAT slow, not like you're mining with monero ... isn't it just a wallet?
Building webkit-gtk without SSE2... now there's a speed compromised build...

I'd file a bug for the overlay if you haven't already and link to this thread. |

You're actually mining Monero ?
I thought you just needed this for wallet and such.
Mining Monero isn't worth it, even with the strongest cpu. |

No I'm not mining, it is just the wallet with the whole blockchain stored on a hard drive. But with that 12 years old CPU and 10 years old HDD (@5400rpm ).. synchronizing the blockchain is still a gigantic pain (I also have LUKS on top of that lol), even with --block-sync-size 20 passed to the daemon startup flag; so I would not touch any mining stuff at all with that kind of setup. |

I get it, nice 
I like Monero, my favorite coin.
I actually used the same app (cli) to create wallet, but I compiled it manually, without ebuild.
Tried to mine it for a while with xmr-stak on few machines, even with one core2 , to see how it goes on each, I think it actually worked on core2 but was very slow obviously. |
