As there is already a report about "intrin.h" problem, so I think maybe my problem could also be solved by someone's help.

I'm using Eigen 3.2.2 with Visual Studio 6 (windows XP).

After I included "Eigen/Dense" in a very simple demo, it showed "fatal error C1083: Cannot open include file 'intrin.h': No such file or directory"

As I know, "intrin.h" only appears in Visual Studio 2005 or newer version of Visual Studio, so I found and copied this file from another computer. After that, it showed to me another ".h" file was needed, so I copied again. But some files were still needed.

At last I found the code "#include <intrin.h>" in "Eigen/Core", and commented this line. Then there were more than 100 errors reported.

So can anyone help me about this？

Thank you very much!

ps，in my current system, there is no intrin.h, x86intrin.h or mmintrin.h.. I have no idea what to do now..

Really hope somebody could help me.

Sorry, but it is very unlikely that such an old compiler manages to parse/compile Eigen's code. Regarding intrin.h you might workaround by defining _WIN32_WCE, even though your system is not WINCE.

Thank you for your reply.
I have tried what you told me, but it did not make it.
Maybe I need update my Visual Studio now.
