Compilation sous Windows de OpenCV 1.2

Bonjour

J'essaye de compiler OpenCV 1.2 sous Windows XP à partir des sources.

Pour cela, j'ai sur mon PC :
MSYS 1.0 ( http://www.mingw.org/wiki/msys)
MingW 5.1.4 ( http://www.mingw.org/ )
CMake 2.6 ( http://www.cmake.org )

J'ai suivi la procédure :
- decompresser le source
- créer un répertoire
- lancer cmake-gui, configurer et générer les fichiers makefile
- lancer mingw32-make

Et la j'ai une erreur C++ qui apparait :

Code:

Est-ce que quelqu'un peu m'aider ?

Voici la ligne incriminée dans cxoperations.hpp :

Code:

1
2
template<typename _Tp> inline Point_<_Tp>& Point_<_Tp>::operator = (const Point_& pt)
{ x = pt.x; y = pt.y; return *this; }

Cordialement
