Re: [eigen] 3.3.8 expected on September 7

[David Tellenbach <david.tellenbach@xxxxxx>]

Hi Edward,

Thanks for your effort. 

I think this is issue #1950 (https://gitlab.com/libeigen/eigen/-/issues/1950).

Thanks,

David

I've never tried to compile eigen tests before. So from build dir, I ran:

cmake .. -DEIGEN_TEST_BUILD_FLAGS="-j 8" -DEIGEN_TEST_CXX11=ON -DEIGEN_TEST_FMA=ON -DEIGEN_TEST_AVX=ON >& cmake_log.txt

And I was surprised to see:

-- Performing Test EIGEN_COMPILER_SUPPORT_CPP11 - Failed

But this is the latest MSVC 2019 compiler so it shouldn't fail.

I had no BLAS installed but I still expected to find Eigen BLAS?

CMake Warning at cmake/FindBLAS.cmake:1371 (message):
  BLA_VENDOR has been set to All but blas libraries could not be found or
  check of symbols failed.

Thanks,

Dear all,

let me start by taking this opportunity to thank David for revitalizing Eigen's developpement.

Thank to that, at long last we're having a new release of the stable 3.3 branch within a few days. Since it receives many more changesets than usual for such a minor release, it would be very welcome if some of you could test it with your favorite compiler and options:

git clone https://gitlab.com/libeigen/eigen -b 3.3 eigen3.3

cd eigen3.3

mkdir build

cd build

# run cmake adapting the options to your Eigen's usage, e.g.:

CXX=clang++-9 cmake  .. -DEIGEN_TEST_BUILD_FLAGS="-j 8" -DEIGEN_TEST_CXX11=ON -DEIGEN_TEST_CUDA=ON -DEIGEN_TEST_FMA=ON -DEIGEN_TEST_AVX=ON -DEIGEN_TEST_OPENMP=ON

# run ctest while submitting to cdash:

ctest -V -D Experimental -j 8

Cheers,

Gaël
