Re: [eigen] 3.3.8 expected on September 7

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,

-Edward

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
