Problems with luarocks install cv - lipopenblas dependency
gbenaa opened this issue · 3 comments
Hi, I'm having problems installing the cv module - have not been able to find the problem reported elsewhere. Will continue to try to resolve but any help appreciated.
Operating Environment:
Ubuntu 16.04.2 LTS
OpenCV 3.1.0
Steps to recreate:
$ sudo luarocks install cv

Hi, have you tried installing OpenBLAS?
Thanks, I believe it is installed but I'll double check.
My guess is that it's an OpenCV installation issue. I suggest running OpenCV tests (for example, do make test at OpenCV build directory) to verify this.
