Problems with installation from source compilation

[furletov]

Hello!

During the installation of HARK from source compilation, on the step of installing hark-core error appears:

/home/furletov/hark/hark-core-3.0.4/src/BF_Matrix.cc: In member function ‘const BF::Matrix BF::Matrix::multiplied(const BF::Matrix&) const’:

Hello.

We have found out that the cause of the error is a bug in the cblas.h file in the libopenblas-dev package.
As a workaround, this package needs to be purged first before building hark-core.
Please try the commands below.

cd hark-core-*.*.*
mkdir build
cd build
sudo apt purge libopenblas-dev
cmake -DENABLE_RASP24=OFF -DENABLE_WS=OFF ..
make
sudo make install
sudo apt install libopenblas-dev

Also, the installation instructions has been updated.
Please see it for reference.

Best Regards,
HARK Support Team
