[Digikam-devel] Re: [Bug 267789] Make face detection (kface) and geo tagging (kmap) optional features

[Gilles Caulier]

Alex,

I compiled and installes libface from svn trunk and tried to compile
libkface. It doesn't work :

[gilles at localhost libface]$ svn up
À la révision 286.

[gilles at localhost libface]$
[gilles at localhost libkface]$ make
