OPENBLAS COMPILING

[wesjane8]

Hello!
I am trying to install the KALDI toolkit. I must install the OpenBLAS.

While compiling the OpenBLAS i get this error :

matcopy_k_cnc.o zomatcopy_k_rnc.o zomatcopy_k_ctc.o zomatcopy_k_rtc.o zimatcopy_k_cn.o
zimatcopy_k_rn.o zimatcopy_k_ct.o zimatcopy_k_rt.o zimatcopy_k_cnc.o zimatcopy_k_rnc.o

ar: the modifier "u" is ignored since "D" is the default (consult "U")

../Makefile.tail:40: recipe for target 'libs' failed

Makefile:145: recipe for target 'libs' failed
make: *** [libs] Error 1
make[1]: Leaving directory '/home/user/Bureau/kaldi/tools/OpenBLAS'

I see that to solve this problem I should run: make clean , make TARGET=Haswell and make BINARY=32 next build. I do these steps, and also with make BINARY=64. But in all cases, i cannot install the OpenBLAS. I get the same error.

MAY YOU PLEASE HELP ME TO SOLVE THIS PROBLEM. THANK YOU

Which version of OpenBLAS, what cpu ? Did you try with target "HASWELL" (all capital letters) ?

I tried with capital letters i get the same error

Strange, 0.3.5 should compile without problems on 7200U (Kaby Lake should be automatically detected as Haswell) in either 32 or 64 bit mode. (Using either just make or make BINARY=32 - I tried it on my i7-7200U just now to be sure it works. The only difference is that I am running a 64bit Linux, but this should not matter).

You must run make clean between build attempts. Probably worth trying 0.3.7, though haswell was not broken with 0.3.5
For 32bit system on your CPU - highest possible TARGET will be NEHALEM as AVX and better extensions are not reachable from 32bit OS
Please record the build log with script command, the error of missing file is preceded long ago (by means of log) with some error building that file.

I want to see your build log

Yes, can you please first run make clean, and then run make >logfile.txt 2>&1 (which should redirect all compiler messages to a file), and upload the logfile.txt here ?
