Issue Details

Project build error during the linking stage. An error related to vtable. I don't use a virtual table in my project

Hello, could you give more information about how exactly you compile your project?

mglisse avatar Oct 01 '25 07:10 mglisse

I can download my project in its entirety so you can check it out. My project is small

Joraslav avatar Oct 01 '25 17:10 Joraslav

What Marc is asking for are compilation flags and how you do compile. You are showing link errors while the library is header only.

sloriot avatar Oct 02 '25 06:10 sloriot

@Joraslav Is that project DownScalerSTL available somewhere on Github, so that we can check by ourself?

lrineau avatar Oct 06 '25 07:10 lrineau

Bump @Joraslav
