Doesn't compile #502

What's your CPU and OpenBLAS version? Is it develop branch? Could you give me the full log? |
|
Open Blas was downloaded today by clicking on the "tar" icon at http://www.openblas.net/. It's being compiled on a VM. The host CPU is s 64-bit Xeon. Here is as much of the log as I am allowed to cut and paste. The limit is 262144 characters. bash-4.1$ make -j4 |
|
What's the output of /proc/cpuinfo |
|
[hornenj@c6build64 ~]$ cat /proc/cpuinfo processor : 1 processor : 2 processor : 3 |
|
Could you try |
|
It builds now, thanks. But does that mean I have a CPU specific binary that I can't deploy to other machines? |
|
Are these all virtual machines? I think the nehalem kernels can work on 2015-02-10 11:18 GMT-06:00 Nigel Horne notifications@github.com:

Some are virtual most are physical. All are wintel. |
|
Could you give me the physical cpuinfo? Is it possible to give me the access to a virtual machine. I want to fix 2015-02-10 11:32 GMT-06:00 Nigel Horne notifications@github.com:

Sorry, no I cannot do that. However, I can help you with running any diagnostics that will help you. |
|
@xianyi I am also having this issue, on a Haswell host, using QEMU with cpu=host. I can give you access to a VM, if you email me. |
|
Actally, I found a bug in my VM configurations, correctly passing in all the CPU features fixes it... |
|
@cmr , Great! Could you create a wkipage on OpenBLAS wiki? |
|
@xianyi sure, I'll write that up tonight. |

@xianyi Added a FAQ entry. Here's the |

@cmr , Thank you very much. |
Fixes #10856 The SSE_GENERIC target fails to build with a "sgemm_kernel.o: No such file or directory" error. Several upstream bug reports exist for this: OpenMathLib/OpenBLAS#502 OpenMathLib/OpenBLAS#685 In both cases, upstream suggests using a different target definition instead. E.G. from issue 685: You may use NORTHWOOD on x86: make TARGET=NORTHWOOD that uses SSE2 instructions. It's very hard to find non-SSE2 x86 CPUs today. For x86-64 use the PRESCOTT target So drop the SSE_GENERIC target. The only x86_64 variant we support not covered by a more specific openblas target is the default variant, nocona and jaguar. Nocona was a Xeon variant of the P4 "Prescott" architecture, so use the PRESCOTT openblas target: https://en.wikipedia.org/wiki/Xeon#Nocona_and_Irwindale Jaguar is from the Bobcat family, so use the BOBCAT openblas target: https://en.wikipedia.org/wiki/List_of_AMD_microprocessors#Bobcat_core_architecture_(APU) [Peter: add Jaguar as pointed out by Arnout] Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
