So I tried to compile on my newer MacBook Pro (Intel i7; OS 10.6.6) with Xcode (and YASM 1.1.0) installed using the tarball version 0.8 of cpuminer with chromicant's patch. Indeed, the previous issue I had with libcurl seems to be machine-specific thing, but I ran into another problem. The configure runs fine but I run into a "in x86_64/libx8664.a, file was built for unsupported file format which is not the architecture being linked (x86_64)" error while trying to make amd2_sse64 module.
Here is the output after running make:

Code:

Making all in x86_64
/usr/local/bin/yasm -f elf64 sha256_xmm_amd64.asm
rm -f libx8664.a
ar cru libx8664.a sha256_xmm_amd64.o
ranlib libx8664.a
ranlib: warning for library: libx8664.a the table of contents is empty (no object file members in the library define global symbols)

Any ideas? If I make without the sse2_amd64 module it builds and runs fine using the original algorithms as you may have guessed.

Try replacing "-f elf64" with "-f macho64" in the x86_64/Makefile as a workaround. Also, you need to make sure you're producing a 64-bit binary while you're compiling. Can't remember how to do that with XCode, but if you don't, the SSE2 code as written will fail. The code uses the added registers that come with the x86_64 architecture to prevent reading/writing to memory.
