Compiling gnfs-lasieve4I1?e on for AMD 64

[FactorEyes]

I'm running 64-bit Linux on AMD Opterons.

Running "make x86_64" produces a slightly slow set of gnfs-lasieve4I1[234]e binaries, and also makes a procrels which consistently crashes.

The secret may lie in the target "common" in the top-level makefile.

common :
        echo "#define GGNFS_VERSION \"$(VERSION)-$(ARCH)\"" > include/version.h
        @cd src/lasieve4 && rm -f -r asm && ln -s piii asm
        @HOST=generic ARCH=$(ARCH) $(MAKE) -C src

I believe, for starters, that "piii" above should read "generic" instead, and then I must create a header file siever-config.h in the src/lasieve/generic/ directory from the siever-config64.w example, but all attempts lead to errors.

Am I looking in the right direction? Any pointers?

You must be using an old source. The common target should use the ppc32 directory:

common :
   echo "#define GGNFS_VERSION \"$(VERSION)-$(ARCH)\"" > include/version.h
   @cd src/lasieve4 && rm -f -r asm && ln -s ppc32 asm
   @HOST=generic ARCH=$(ARCH) $(MAKE) -C src

Yes, that's a bad naming convention, but correct. :) You can get the latest source using SVN from Sourceforge.

My error. I had replaced "ppc32" with "generic", and then switched it back to "piii" for some weird reason.

It doesn't work anyway -- I think the lack of assembler code files in the /generic directory is one among many reasons for this.

Your post on another thread just dealt with this anyway: the assembler code for AMD64 hasn't been written yet, at least for public consumption.
