I had the same issue. What does your makefile.config look like? Turns out I set BLAS := OpenBlas when I should've set BLAS := open.

[surajits]

hii.... i set BLAS:= open in my makefile.config and i did "make all"...and it worked. But when i typed the next command "make test"..then again i am geting the same error.....if u figured out just let me know
thnks :)

[jmhessel]

Did you try doing a make clean before you re-made with this setting fixed?

[surajits]

yeah i did,,,,,even i tried to install again and again..is ur make all
command working??.....i feel there some is reference problem in
caffe_master folder

Closing as this does not appear to be a bug with Caffe, but an issue with build configuration/dynamic linking. Please ask installation questions on the caffe-users list. Thanks!

Have you solved the problem?

[ysh329]

@DanlanChen Have you solved the problem too? :crying_cat_face:

[Merlin2013]

check if there is a space after BLAS := mkl
make sure no space after mkl

@Merlin2013 Your answer worked for me! Thank you very much!!
