Could not build xenoncat object file into zcash daemon.

Hi,
I am trying to integrate your code into zcash build.

I am getting following error.

/usr/bin/ld: pow/xenoncat/equihash_avx2.o: relocation R_X86_64_32S against `.data' can not be used when making a shared object; recompile with -fPIC

Would it be possible to modify assembly code to generate PositionIndependentCode(PIC) from ASM?

I believe this has been fixed a few days ago with the commit "Bug fix: 32-bit address assumption related"
The current version does not have R_X86_64_32S. Please retry with the latest version of equihash_avx2.o.
