Error installing OpenBlas on Linux Mint

[Gabriel Lipnik]

Hey!

I wanted to install Sage and got an error message while installing OpenBlas. Here's the log file, can someone help me?

Whats your CPU? 

 

This seems to be https://github.com/xianyi/OpenBLAS/issues/1139

Try building Sage with

OPENBLAS_CONFIGURE="TARGET=ATOM" make

Thank you very much for your fast answer!! Works well now.

If you are still interested in my CPU: Intel(R) Core(TM) i7-7500U CPU @ 2.70GHz

More infos in the file attached.

Don't know why, but I can't post attachments (error 303)...

I had the same issue with openblas, but on a Thinkpad 11e with an intel Celeron N2940 processor. Setting OPENBLAS_CONFIGURE="TARGET=ATOM" fixed this for me as well.  https://groups.google.com/d/msg/sage-devel/-Exvx0bane8/9kC8hBEFBwAJ

I assumed this was limited to lower-end processors like the Celeron, but since you are on an i7 I guess not! I wonder if there is anything we can do to help improve the CPU detection issues? At any rate it's pretty easy to fix once you know to set the cpu TARGET variable manually.
