errors in Windows

hey @tcoppex , are you using another ofxTriangleMesh fork? I am getting the linked fork on the README... This is on Visual Studio 2017, OF 0.10

Yes I totally did O_O", I forget old commits I have not pushed at the time. I just updated the ofxTriangleMesh repository, it should work now.

Thanks for the feedback :+1:

hey @tcoppex ,

Trying to make it work on Windows again.. I changed the VS project settings to enable c++ 17, but I am having errors on OF side:

Severity    Code    Description Project File    Line    Suppression State
Error   C2757   'filesystem': a symbol with this name already exists and therefore this name cannot be used as a namespace name (compiling source file ..\..\..\addons\ofxFontSampler\src\ofxFontSampler.cpp)   example c:\program files (x86)\microsoft visual studio\2017\community\vc\tools\msvc\14.16.27023\include\fstream 24

...

There's some error on triangulateConstrainedDelaunay method:

      // Triangulate & generate Voronoi diagram for the glyph.
      {
        auto &mesh = glyph_mesh->face;
        mesh.triangulateConstrainedDelaunay(polygon_, 24, 620); 
        mesh.generateVoronoiDiagram();
      }

could you or do you know how to remove the c++17 parts to the more "OF standard" c++14?

I found some info about how to switch an OF project to c++ 17 but is not trivial: https://github.com/openframeworks/openFrameworks/issues/6585

Regards.

Hi @moebiussurfing,

You're right about C++17 code on OpenFrameworks libraries, this project was compiled with gcc 7.5.0 and c++14 though, so this might be on the MSVC side of things as regardings filesystem neither the library nor its keyword is used in the project (or ofxTriangleMesh). I'll take a look when I have a moment, thanks for the head-up.

I believe https://github.com/openframeworks/openFrameworks/issues/6832 is related so I close the issue.
