cblass_sgemm error in libblass

[Joaggi]

Hi Daniel,

I tried to compiled again with the last commit, but unfortunately, I received another error.

The error is:

/usr/bin/ld: /tmp/ccfo33G4.o: reference without defined symbol 'cblas_sgemm'
//usr/lib/x86_64-linux-gnu/libblass.so.3: error adding symbols: DSO missing from command line
colect2: error: ld returned 1 exit status
Makefile:95L: recipe for target 'pcatestf' failed
make: *** [pcatestf] Error 1

The dependencies that I installed was the following:

sudo apt install libssl-dev
sudo apt-get install libz-dev

sudo apt-get install gfortran
sudo apt-get install libblas-dev liblapack-dev

apt-get install libfftw3-dev

I'm using Ubuntu 18.04

It seems to be a BLAS linking issue. You can either modify the Makefile to replace BLAZE_BLAS_MODE=1 with BLAZE_BLAS_MODE=0 (to eliminate using BLAS entirely), or try to enable blas linkage.

sudo apt-get install libblas-dev liblapack-dev

might be what you need.

I tried two things:

The first one:
sudo apt-get install libblas-dev liblapack-dev

It was not successful.

The second one:
apt-get install libatlas-base-dev

This also did not work as expected :(.

The only thing that worked as you told me, was to disable Blas :(.

I don't know why I couldn't compile with it.
