do not works at centos 6 x64

[hsn10]

If you try to compile git source code on Centos 6 64 bit, it compiles right but do not works. All computed results are rejected by server. I guess that they are computed wrong.

It would be nice to add some kind of selftest to --benchmark option

Official windows 32bit build has same problem - nothing is accepted, but official 64bit linux version works fine.

Could you please provide the exact command line parameters you use (feel free to hide your username and password with asterisks), and the full output of a few minutes mining with --debug?

[hsn10]

from official windows build?

[pooler]

From whatever build that is not working for you. I was unable to reproduce the issue you reported.

[hsn10]

in freebsd it didnt worked until i did nomacros.pl before compiling. In centos i tried both methods and none worked. Debug output from working freebsd version vs non working windows 2.3.1 is same.

Your calculated hash is different from server calculated hash. Its most likely compiler problem. Adding selftest would help.

[pooler]

Did you perform all these test runs on the same machine?

You said "in freebsd it didnt worked until i did nomacros.pl before compiling". Does that mean that without running the script you couldn't get the miner to compile, or that it compiled but the server rejected its solutions?

Also, what do you mean by "debug output from working freebsd version vs non working windows 2.3.1 is same"? If one version is working and the other is not, how can the output be the same?

By the way, the -s option is completely useless in Stratum mode.

[hsn10]

on freebsd i can get it compiled even without running nomacros.pl but all results are rejected.

[hsn10]

i have several machines. On all freebsd types i have (9 and 8, 32 and 64 bit) i have to run ./nomacros.pl to get working version. I have only 64bit centos 6.4 and if i compile from source with macros or without macros it compiles fine but all results are rejected. If i download official 64build to centos, it works fine.

[hsn10]

debug outputs are same except server always rejects results from nonworking version.

[pooler]

That's odd, as nomacro.pl should not change the semantics of the code. What compiler (and what version of it) did you use? Have you tried mining at a different pool, just to make sure it's not a server-side issue?

[hsn10]

gcc (GCC) 4.2.1 20070831 patched [FreeBSD]

no

[pooler]

Could you please test again using the latest code from the git repo? I have just pushed a fix for a bug that can result in undefined behavior if the mining server gives out Stratum jobs with certain characteristics.

[hsn10]

it works now. Tested on 64 bit centos.
