Hi Gael,

I've started builds on VS2017 15.5.1 and VS2017 15.6.0 Preview 1.0 with and without -DEIGEN_TEST_CXX11=ON (I thought that might be useful) between 12 and 2pm, one with -j 9 and the other one without. Both have been running since and haven't completed yet.
One is currently at "Size: 1299K", the other one at "2050K". I read on the wiki that a full rebuild can take up to three hours, but particularly with -j 9 and a good machine (SSD, recent quad-core i7), I am surprised. Is this to be expected?

Thanks a lot for starting the builds. I run it with MSVC 2012 in a VM without multithreading and it completed in 2 to 3 hours max. The build/test/Debug folder is about 6GB. So:

1 - make sure you've updated to 3.3 (the devel branch is more involved, because there are more tests!)

2 - To speed up builds you can add /DEIGEN_STRONG_INLINE=inline in CMAKE_CXX_FLAGS

3 - "ctest -j 9" won't speedup the builds, but only the run of the tests.

So for faster parallel builds (4 processus):

cmake . -DCMAKE_CXX_FLAGS="/MP4 /DEIGEN_STRONG_INLINE=inline"

I've essentially followed your instructions and then

cmake .. -G "Visual Studio 15 2017 Win64"
ctest -C Release -D Experimental -j 9

>> there is small issue, the last line should be:
>> ctest -D Experimental

So that means no "-C Release"? What will that run?

all tests will be run instead of the ones in eigen/test only (in theory, here none were run, which is why I recommended to remove this option).

In case of problems, you can rerun the tests without rebuilding binaries that are already up-to-date with:

ctest -D Experimental --build-noclean -VV

-VV is useful to see what's going on...

thanks again.

I'm happy to let them run & finish or restart them with modified commands, just let me know.

Kind regards,

Patrik

For the record, the build is green for msvc 11 (2012), it would still be welcome to get feedback for MSVC 2015 and 2017.
