[Rcpp-devel] Conflict between RInside and OpenCV

[Xavi de Blas]

Hello again

I deleted .RData and .Rprofile and problem persists.

In order to have OpenCV right-working with last ffmpeg i have so much
versions and compilations and maybe there's a problem difficult to
reproduce.

Can you please post your compilation line?

I'm glad that it's working for you

Thanks
