Error installing OpenBLAS on ubuntu 12.04 precise.

[curioustolearn]

I am trying to install OpenBLAS using the instructions and the download file given here:
http://xianyi.github.io/OpenBLAS/

I get the following error:

../common.h:579:27: fatal error: cblas_noconst.h: No such file or directory
compilation terminated.
make[1]: *** [cblas_isamax.o] Error 1
make[1]: Leaving directory `/home/admin/downloads/xianyi-OpenBLAS-9c51cdf/interface'
make: *** [libs] Error 1

I was having trouble installing Julia and then thought I will install OpenBLAS first but am having the same trouble. Can someone please help?

Thanks.

Did you install perl on your box?

Then, please re-run the make.

make clean
make

Or

perl -ane ' s/\bconst\b\s*//g; print; ' < cblas.h > cblas_noconst.h
make

Same error here, Ubuntu 12.10 with current master (fe98de2). Perl is installed.

When running make, I first get these error messages:

getarch_2nd.c: In function ‘main’:
getarch_2nd.c:12:35: error: ‘SGEMM_DEFAULT_UNROLL_M’ undeclared (first use in this function)

getarch_2nd.c:70:50: error: ‘ZGEMM_DEFAULT_Q’ undeclared (first use in this function)
make: *** [getarch_2nd] Error 1

then a few files compile successfully, then the same error occurs that @curioustolearn got.

When I generate cblas_noconst.h manually, I get a new set of compile errors, including

It looks like OpenBLAS didn't recognize your CPU. Did you fix this problem?

What's your CPU?

[larsmans]

I have an AMD A6-3400M APU (CPU + Radeon GPU on one chip).

From what I could find, this thing is also called the Llano and is a
K10/Barcelona variant, so I set TARGET=BARCELONA. That seemed to work,
although I still have to test OpenBLAS thoroughly.

[larsmans]

Anyway, it seems like the original problem should be fixed (@curioustolearn, can you confirm this?), so maybe the issue should be closed and I can make a new issue for building on AMD APUs.

[dcarrera]

I'm not sure that the issue is fixed. I have the same system as larsmans (AMD A6 APU). I can compile with if I set the target to BARCELONA.

Same problem .
My CPU is CORE i5 6300HQ, which TARGET should I Select?

[martin-frbg]

TARGET=HASWELL should work - which version of OpenBLAS are you trying to build ? ("SkyLake" type CPUs should be autodetected since about version 0.2.15, released more than a year ago)
