C1083: Cannot open include file: 'Eigen/Eigen': No such file or directory #4265

Closed friente closed 4 years ago

friente commented 6 years ago

Hello,

I'm just writing some test code using shogun lib on windows. I'm using dynamic linking against my executable. However, I get an error when I include:

#include <shogun/mathematics/eigen3.h>

The error is:

C1083: Cannot open include file: 'Eigen/Eigen': No such file or directory

Where should be located the eigen library within the installation folder? Because I couldn't find them. I couldn't find the eigen directory within shogun/lib/external. Thanks

vigsterkr commented 6 years ago

@fyoda indeed this was an error in the previous release... now it's fixed in develop, basically any third party library will be available under shogun/third_party folder. for the time being you either start using the latest version of shogun or add the eigen headers under shogun/lib/external/eigen manually

friente commented 6 years ago

@vigsterkr Should I rebuild shogun starting from develop? Or can I just use my previous build and eigen 3.3.4 within theshogun/lib/external/eigen manually?

vigsterkr commented 6 years ago

@fyoda you should be able to use eigen 3.3.4 and put there manually.. .note that you should use -isystem gcc/clang flags when you compile shogun

vigsterkr commented 6 years ago

btw which header includes #include <shogun/mathematics/eigen3.h>?

friente commented 6 years ago

@vigsterkr I'm building the lib with MSVC 2015, the -isystem should be set by CMAKE when generating the MSVC solution (I think). #include <shogun/mathematics/eigen3.h> includes:

#include <Eigen/Eigen>
#include <Eigen/Dense>
#include <Eigen/Sparse>
vigsterkr commented 6 years ago

@fyoda oh so you are having this error while you are building shogun? i thought when you are using it. if it's build time problem, then there's a bug indeed

friente commented 6 years ago

I'm getting this error in both cases, when I build shogun but also when I'm using it. However, even if I get the many of those errors during the build phase, the .lib is genered.

vigsterkr commented 6 years ago

i'm just checking the headers and none of the external headers include the mentioned eigen3.h so you shouldn't have this problem while using shogun externally. but of course the build problem (when you try to build the library) should still be fixed... i remember that you were having some custom build mechanism. note the generated MSVC 2015 works by default - see our appveyor builds.

friente commented 6 years ago

@vigsterkr I don't have standard MSVC 2015 build mechanism. The problem with me was the debug and release build. I solved by changing manually the Runtime lib used for the debug, because it doesn't switch automatically in visual studio.

vigsterkr commented 6 years ago

@fyoda can you provide me the compiler flags for the shogun.sln?

friente commented 6 years ago

@vigsterkr In the following you can find all options for the libshogun solution:

/GS /TP /W1 /Zc:wchar_t /I"C:\Users\myUser\Downloads\shogun\src" /I"C:\Users\myUser\Downloads\shogun\build\src" /I"C:\Users\myUser\Downloads\shogun\src\gpl" /I"C:\Users\myUser\Downloads\shogun\build\MSDirent\src\MSDirent\include" /I"C:\Users\myUser\Downloads\shogun\build\src\shogun\lib\external\eigen" /I"C:\Users\myUser\Downloads\shogun\build\src\shogun\lib\external" /Gm- /O2 /Fd"libshogun.dir\Release\libshogun.pdb" /Zc:inline /fp:precise /D "CMAKE_INTDIR=\"Release\"" /D "_MBCS" /errorReport:prompt /WX- /Zc:forScope /Gd /MD /openmp /Fa"Release/" /nologo /Fo"libshogun.dir\Release\" /Fp"libshogun.dir\Release\libshogun.pch"

Additional options are: %(AdditionalOptions) /std:c++14 /bigobj -std:c++14

vigsterkr commented 6 years ago

ok so basically this:

C:\Users\myUser\Downloads\shogun\build\src\shogun\lib\external\eigen

should make sure that eigen is available. that dir is being created by cmake and by adding eigen to your project. check if eigen is actually there.

friente commented 6 years ago

@vigsterkr No there is no eigen folder there. The build process downloads the 3.3.4 but then it's not copied there automatically. I can try rebuilding shogun putting the eigen in that folder.

vigsterkr commented 6 years ago

mmm that's weird as this should be autogenerated by cmake. are you sure you are checking it under build dir and not the root of the repo?

friente commented 6 years ago

I'm sure, in C:\Users\myUser\Downloads\shogun\build\src\shogun\lib\external there is no eigen folder

vigsterkr commented 6 years ago

for the sake of argument, could you create a new build directory, say build-test and run cmake and try to build shogun.sln

friente commented 6 years ago

Ok, I created a new build-test, build again the lib but I still get the error mentioned before.

Error C1083 Cannot open include file: 'Eigen/Eigen': No such file or directory libshogun C:\Users\myUser\Downloads\shogun\src\shogun\mathematics\eigen3.h 14

vigsterkr commented 6 years ago

mmm that is super interesting.... so then i guess this is a bug - that i couldn't reproduce yet... could you put there (C:\Users\myUser\Downloads\shogun\build\src\shogun\lib\external\eigen) manually the eigen 3.3.4? it should fix it.

friente commented 6 years ago

By putting eigen files manually in C:\Users\myUser\Downloads\shogun\build\src\shogun\lib\external\ the Eigen includes within eigen3.h are not underlined in read anymore. I'll let you know at the end of the build process.

friente commented 6 years ago

@vigsterkr Now the build process fails. Here is the error list of visual studio. shogun.lib is not generated.

distributions\Histogram.cpp.obj doesn't exist on that folder. Also the include #include <unsupported/Eigen/MatrixFunctions> in DenseMatrixExactLog.cpp cannot be found.

doh... i dont really get why it cannot find unsupported/Eigen/MatrixFunctions

friente commented 6 years ago

@vigsterkr Where it should be located?

vigsterkr commented 6 years ago

@fyoda this should be in C:\Users\myUser\Downloads\shogun\build\src\shogun\lib\external\eigen

friente commented 6 years ago

@vigsterkr I'm sorry I forgot to copy that folder. C1083 solved. I still get the other errors LNK1181.

vigsterkr commented 6 years ago

mmm i'm not so sure where the linking error is coming from :(

friente commented 6 years ago

@vigsterkr By manually adding eigen folder in C:\Users\myUser\Downloads\shogun\build\src\shogun\lib\external\ the C1038 got fixed. Now the shogun.lib build successfully.

I still have a problem when using the lib. I cannot use Eigen within my code. If I include #include <Eigen/Eigen> I get again the C1038 error posted above. I have included all paths specified within ShogunTargets.cmake in my Qt .pro file:

${_IMPORT_PREFIX}/include/shogun;
${_IMPORT_PREFIX}/include/shogun/lib/external/MSDirent;
${_IMPORT_PREFIX}/include/shogun/lib/external/eigen;
${_IMPORT_PREFIX}/include/shogun/lib/external/rxcpp;
${_IMPORT_PREFIX}/include;

Fixed, the problem is that in shogun\include\shogun\lib\external\eigen\Eigen only the src folder is copied within the install directory and not the other files.

vigsterkr commented 6 years ago

@fyoda if you wanna use yourself Eigen for some reason in your code you need to provide the eigen for yourself. meaning: if you just simply use shogun classes you should not have problems of finding eigen, as it's actually only used during compile time of the library...

ok so basically the problem here is mostly about things that got already fixed imo - in develop. i'll test it during the weekend on my windows VM just to make sure, i.e. will leave the ticket open till then

friente commented 6 years ago

Ok, thanks! Yes basically the problem is about the not copied eigen files within the build directory.
