QuoteOof.  This is going to be a problem on a 32 bit system.  There are some very x86_64 specific chunks of code in the assembly-optimized sha512 routines (which you need if you want this thing to be fast).

Sorry.

I was afraid of that, no problem. Maybe finally a good reason to covert my main desktop to 64bit...

I googled Haswell and since mine isn't one I tried commenting out the failing sha512_avx2.S bit in the makefile.unix , since apparently I can't use it anyway, but now it fails with the following. Not sure if I need to do more than mess with the makefile...

Hi dga

QuoteAre you using an older version of gcc?  If so, try upgrading

I have
gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu9)
the latest available on ubuntu. is that too old ?

Quoteor I can explain how to remove the need for the avx2 code if you're not on a Haswell CPU.

I have to admit I'm not sure if I have a HASWELL Cpu, I have the following processor.
model name      : Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx rdtscp lm constant_tsc arch_perfmon pebs bts xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm pcid sse4_1 sse4_2 popcnt tsc_deadline_timer aes xsave avx lahf_lm ida arat epb xsaveopt pln pts dtherm tpr_shadow vnmi flexpriority ept vpid

If it's an easy fix, e.g. to comment some code out I'd appreciate it.

p.s. thanks for all the effort, I really appreciate keeping the source open !

I got the following trying to compile...
anyone know how to fix this ? I'm on a 32-bit kernel(PAE), not sure if that's relevant...

I'm new here, but we don't seem to have found a block for over 12 hours... is that normal or is there an issue with the pool?
