linking ipopt against openblas

Question

Currently, I am trying to build Ipopt linking against openblas. I downloaded the openblas source and did make in the parent directory.

The configure script of Ipopt has several options to link against blas:

I tried ./configure --with-blas="-L/home/moritz/build/CoinIpopt_test/ThirdParty/OpenBLAS-0.2.14/libopenblas.so"

but I do get the error

checking whether user supplied BLASLIB="-L/home/moritz/build/CoinIpopt_test/ThirdParty/OpenBLAS-0.2.14/libopenblas.so" works... no configure: error: user supplied BLAS library "-L/home/moritz/build/CoinIpopt_test/ThirdParty/OpenBLAS-0.2.14/libopenblas.so" does not work

Any tips how to achieve what I want ? Finally, I would like to make a conda package. I do have installed openblas with anaconda. But I do get the same error message if I link against the installed libopenblas.so

Managed to get it work. I had to install openblas to a directory of my choice by

make install PREFIX=/home/....../

aferwards I compiled Ipopt using

./configure --with-blas-incdir="-I/home/.../openblas/include/" --with-blas-lib="-L/home/.../openblas/lib/"

How did you find that solution (source)? Also, I purposely misspelled the path to my blas lib, and it didn't give me an error. – Agrim Pathak Jun 26 '16 at 11:38
Uh, that is too long ago – Moritz Jun 26 '16 at 13:57
