Building failiure on VS2013

[billy-antoine]

Hi,

First of all congratulation for your amazing work.
I would like to use openMVG in order to compare its SfM results with the one available in openCV.
However, I can't manage to build it...

I used CMake-GUI to generate the project files and Visual Studio 2013 to build the libs.
When I open the generated solution and build the ALL_BUILD project (with Release as compilation mode and as Administrator) I get three main errors. The first one comes from metric_hamming.hpp:

Erreur 1377 error C2061: erreur de syntaxe : identificateur 'uint64_t' C:\openmvg\openMVG\src\openMVG\matching\metric_hamming.hpp 91 1 openMVG_sample_image_matching

The second one seems to be from Cameras_Common_command_line_helper.hpp:

Erreur 692 error C2676: '|' binaire : 'openMVG::cameras::Intrinsic_Parameter_Type' ne définit pas cet opérateur ou une conversion vers un type acceptable pour l'opérateur prédéfini C:\openmvg\openMVG\src\openMVG\cameras\Cameras_Common_command_line_helper.hpp 44 1 openMVG_main_GlobalSfM
And The last one tells me that it can not find some libs:

Erreur 330 error LNK1181: impossible d'ouvrir le fichier en entrée '..\..\Windows-AMD64-\Release\openMVG_sfm.lib' C:\openmvg\openMVG\build\software\SfM\LINK openMVG_main_ComputeSfM_DataColor

Finally, 42 projects have failed to be correctly generated (31 managed to make it).
Could someone help me ..?

Thanks,

Hi @billy-antoine

1. As you will see here VS2015 is required to build OpenMVG. So if you can please install and use VS2015.

2. If you cannot install VS2015, you can use an OpenMVG fork that have a VS2013 compatibility here. This Fork should be close to OpenMVG v1.1.

Please tell me how the compilation goes once you have chosen the solution 1 or 2.
Looking forward to guide you, once OpenMVG will be compiled ;-)

Hi @pmoulon ,
Thank you for your answer, I did not notice the version requirements... Unfortunately it seems that I have the same issues with the given fork.
I will try to get VS2015 and build it again. I won't hesitate to ask for your help if needed, thank you !
