I get: Code: /var/folders/n7/n7Do3Krz2RWPeE+1YxvhUU+++TM/-Tmp-//cc8PgHsQ.s:879:suffix or operands invalid for `call’ … compiling cryptopp/sha.cpp (latest SVN source) on my Mac (gcc version 4.2.1). I fixed it by adding -DCRYPTOPP_DISABLE_ASM to my makefile; perhaps somebody with more experience compiling C++ on a Mac can figure out a better fix. Was that the only […]
Read moreRe: Having problems specifing -datadir
Whilst not amazingly critical, i find it strange that i consistently get the below error messages from the console and debug.log when i try to specify the datadir option with anything other than the period char (current directory). This is using the bitcoind program on an archlinux terminal session, im […]
Read moreRe: Bitcoin x86 for Windows
I’ve got some older machines (for the windows client and linux clients) to test with that don’t support SSE2. Mainly if you try to run them, the program just crashes when I tried some of the experimental builds here, but I’ll be glad to test some future official builds to […]

Quote from: BlackEye on July 25, 2010, 22:12:23 I was able to integrate the SHA256 functionality from Crypto++ 5.6.0 into Bitcoin. This is the fastest SHA256 yet using the SSE2 assembly code. Since Bitcoin was sending unaligned data to the block hash function, I had to change the MOVDQA instruction […]

The speedup is about 70%. I credited it […]

Quote from: Olipro on July 26, 2010, 06:39:17 Credit to tcatm for the caching part of the SHA context – this offers absolutely brilliant performance. Additionally, the Intel compiler really comes into its own here as its parallelisation abilities give a massive performance boost over Visual Studio. Performance: 4700khash/s on […]
Read morebitcoind without wxWidgets
I replaced the last of the few wxBase dependencies in bitcoind. bitcoind now compiles without wxWidgets or wxBase in SVN rev 112. main(int argc, char* argv[]) is added to init.cpp. CMyApp and the Startup folder stuff are moved to ui.cpp. ui.cpp and uibase.cpp aren’t linked by bitcoind. The makefiles have […]

So the way I read it. Given two numbers p and q. Which for RSA are supposed to be large primes. Then n = p*q The public key is the two fields (n, e). e is called the public exponent and appears to be chosen from a set of common […]
