On both MinGW GCC 4.4.1 and 4.5.0 I have it working with test.cpp but SIGSEGV when called by BitcoinMiner. So now it doesn't look like it's the version of GCC, it's something else, maybe just the luck of how the stack…

Starting at 67000 is perfect . Yeah, at the moment you'll stop at 74638. It should start slowly creeping up as more nodes upgrade and generate. Linux build links below. The Linux version includes tcatm's 4-way SSE2 SH…

Quote from: knightmb on August 15, 2010, 10:59:04 PM [edit] Just saw your post, I'll build one to less than 74,000 then, should at least save you technical people a few minutes of downloading the new chain. Just leave…

Don't update the block chain download. When you take someone's block chain download, you don't want it right up to the end. A somewhat old one is better so it can download and verify the most recent blocks. tcatm's 4-…

Patch is uploaded to SVN rev 132! For now, recommended steps: 1) Shut down. 2) Download knightmb's blk files. (replace your blk0001.dat and blkindex.dat files) 3) Upgrade. 4) It should start out with less than 74000 b…

Once you have an update, you could download knightmb's block chain. You'll want one that's old enough that it ends before block 74000 so the most recent security lockin will check it. Can someone find the link for that?

It would help if people stop generating. We will probably need to re-do a branch around the current one, and the less you generate the faster that will be. A first patch will be in SVN rev 132. It's not uploaded yet.…

Here's the preliminary change. Look right? I have more changes to make, this isn't all of it. Will SVN shortly. Code: bool CheckTransaction() const { // Basic checks that don't depend on any context if (vin.empty() ||…

Some places where generation will gravitate to: 1) places where it's cheapest or free 2) people who want to help for idealogical reasons 3) people who want to get some coins without the inconvenience of doing a transa…

I just uploaded a quick build so testers can check if I built it right. (I don't have an i5 or AMD) If it checks out, I'll put together the full package and do all the release stuff.

I hope someone can test an i5 or AMD to check that I built it right. I don't have either to test with. I'm also curious if it performs much worse on 32-bit linux vs 64-bit.

Quote from: jgarzik on August 15, 2010, 05:46:27 PM the extended-help might have been based on my idea, but the code was somewhat different. The idea was the main part. When you posted your patch, I realized it should…

0.3.10 has tcatm's 4-way SSE2 as an option switch. Use the switch "-4way" to turn it on. Without the switch you get Crypto++ ASM SHA-256. I could only get this working with Linux. Download: Get 0.3.10 from http://bitc…

Version 0.3.10 patches the block 74638 overflow bug. http://bitcointalk.org/index.php?topic=823 The Linux version includes tcatm's 4-way SSE2 SHA-256 that makes generating faster on i5, i7 (with hyperthreading) and AM…
