.\vcpkg.exe install eigen3:x86-windows
.\vcpkg.exe install eigen3:x64-windows

Both package's provide Cmake targets

Like in this I posted #7902

But for some reason stop worked.

find_package(Eigen3 CONFIG REQUIRED)

target_link_libraries(main PRIVATE Eigen3::Eigen)

visual studio 2015 I have also visual studio 2017 on the same machine non of them works.

I have tried ./vcpkg integrate install without result

I have tried ./vcpkg integrate project but non seems to work.

Hi @ollp
Thanks for posting this issue.
You mean that you cannot use eignen3? If so, please provide your project case.

Hi thanks for answer.
if I add the path in project properties vc++Directories it works.

But I don't think that is idea.

regards ollp

Could you please post the error info if you don't add path in project?
Please also help confirm you have set CMAKE_TOOLCHAIN_FILE.

If possible, please provide your project case.

The biggest problem it does not give any real error no point compile if it cannot find te header file.
CMAKE_TOOLCHAIN_FILE how do I set that?

is that what you mean? i have not done any manual config.`Except in in project properties vc++Directories

If you used CMake project, you need to set CMAKE_TOOLCHAIN_FILE. You can refer to this to learn more about the usage of a port.

.\vcpkg.exe install eigen3:x86-windows --head
.\vcpkg.exe install eigen3:x64-windows --head

find_package(Eigen3 CONFIG REQUIRED)
target_link_libraries(main PRIVATE Eigen3::Eigen)

I have tried ./vcpkg integrate install without result
I have tried ./vcpkg integrate project but non seems to work.

What creates the problem i have no idea if you follow does commands above. That is what I have done.

the screen gives same code as the answer AlvinZhangH posted in this #7902

And you can use

./vcpkg integrate install

./vcpkg integrate project

and find whatever header you need with out manual config?

in project properties?

@NancyLi1013
Copy link
Contributor

So you include the headers in your project, but you cannot find any headers if you don't config the include path in project properties?

Such as adding #include <eigen3/Eigen/src/Core/Array.h>

then try to build the project?

The steps are right?

I didn't met the issue that headers were not found, but there were some errors in the header file.

The errors like this:

yes if you show me how to find it. is there an error log or what?

@NancyLi1013

I added #include <eigen3/Eigen/src/Core/Array.h> in my project. When I built this project, I found the above errors from output item.

I didn't config the include path in project properties manually. Just execute ./vcpkg integrate install and ./vcpkg integrate project.

If you met the same errors with me, in my opinion, this is a bug for eigen3.

As for the issue that you cannot find headers, please restart your Visual Studio after execute ./vcpkg integrate project.

If I don't use integration, the error info like this:

1>------ Build started: Project: ConsoleApplication1, Configuration: Debug x64 ------
