[Mingw-cross-env-list] Linking error with SDL_image

Greetings to everyone

 I've been able to use mingw-cross-env to cross-compile a SDL-based application. However, I tried using a function from the SDL_image library, and I get a link error. 

At first I installed package sdl, then later on I installed package sdl_image. >From what I remember, it brought some other packages (libpng, jpeg, tiff at least, maybe some others).

Here is my command line : 

386-mingw32msvc-g++  -g -O2   -o ube.exe ube.o ../engine/libube-engine.a libube-client.a -llua  -lm -lintl -liconv -L/home/phtrivier/sandbox/src/mingw-cross-env-2.8/usr/i386-mingw32msvc/lib -lmingw32 -lSDLmain -lSDL -lwinmm -mwindows -lSDL_image

The library SDL_image was properly installed in /home/phtrivier/sandbox/src/mingw-cross-env-2.8/usr/i386-mingw32msvc/lib, I have files : 

* libSDL_image.a
* libSDL_image.la

As far as potential dependencies of SDL_image, I also have : 
* libtiff.a (and .la)
* libtiffxx.a (and .la)
* libjpeg.a

(and don't know if there are any other dependencies)

At link time I get a huge list of error, along the lines of

collect2: ld returned 1 exit status

I tried a few combinations of manually adding some other libraries (-lpng, -ljpeg, -lz, -ltiff, -ltiffxx ...) but could not come to a set that worked. 

Is there something wrong with the way I installed package sdl_image ? Do I need to install something else ? Is there a binary than can produce the proper set of ld flags ? 

Thanks
PH
