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.

How often do you get the chance to work on a potentially world-changing project?
There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin-Qt, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.

Was that the only thing I broke in the OSX build?!  Does it actually work after just that one change?

I had to do that for makefile.vc also.  It compiled, but SHA-256 didn't work correctly; it returned the same incorrect hash each time.

We'll disable it now, and if anyone figures out how to fix it, we can re-enable it then.  It's still 1.7x faster from the midstate optimisation.

The Crypto++ ASM SHA-256 works with GCC on Linux and Windows (MinGW).

I uploaded this makefile.osx change to SVN.  (let me know if that compiles now)

I built a TEST-network bitcoind with the SVN r115 changes merged in, and yes, after that one change it's been happily generating coins all afternoon.
I don't use the stock makefile.osx, though-- I setup the dependency directory structure a little differently (for no really good reason).
