Problem compiling Digikam with mingw

[Gilles Caulier]

I remember to have seen this problem in the past, just when i switch
from mingw to TDM-GCC.

It look like mingw header still present in your system somewhere and
come in conflict with TDM-GCC header.

remove mingw properly will solve this problem.

If you have installed mingw using emerge, no chnage : all file are
merged with you KDE windows install.

Personalyy, i install TDM-GCC in C:/TDM-GCC/ (not C:/MINGW).

Respect TDM-GCC tips from this page :

http://tdm-gcc.tdragon.net/start#install

Here all compilation work fine indeep. I'm happy.

Note : I use also M$ MSVC compiler on the same machine. I install 2
KDE4 version on my computer, and to select right path, i use a simple
M$ shell script to init env on the console.

The advange to have both compiler at the same time is to check
warnings and errors, which are very instructive under MSVC. I don't
want to said that MSVC is better than GCC. Sometime yes sometime no.

The next stage for me is to setup a developement env under my new
macbook and check if all work fine with Apple XCode compiler.
