Problem compiling Digikam with mingw

[Francis Corvin]

Gilles,

Belated thanks for your answer. I tried again today: MinGW has been 
completely removed from the system (and it had been before). I have 
now three folders:
- E:\dev-tdmgcc where I instaled TDM-GCC and also downloaded the 
source code via Subversion
- E:\kde4-tdmgcc which is my KDE installation directory
- E:\kde4-tdmgcc-dl which is the KDE download directory

I still have the same problem:
In file included from E:\kde4-tdmgcc\include/lcms.h:185:0,
                  from 
E:\dev-tdmgcc\kdegraphics\libs\libkdcraw\libraw/internal/defines.h:54,
                  from 
E:\dev-tdmgcc\kdegraphics\libs\libkdcraw\libraw\internal\dcraw_common.cpp:29:
E:\kde4-tdmgcc\include\mingw/unistd.h:119:44:
error: declaration of C function 'void usleep(unsigned int)' conflicts with
E:\dev-tdmgcc\kdegraphics/../include/unistd.h:36:29:
error: previous declaration 'int usleep(useconds_t)' here

So it is a conflict between TDM GCC and the KDE libraries and their headers.

When I installed TDM GCC, I chose the MinGW 32 bit option (I cannot 
link exiv2.dll.a with the 64-bit version; I am using WIndows XP). Is 
that the correct choice? Do you remember how you fixed your problem?

Francis
