I'm using mingw-w64 (gcc 4.9.2)
I downloaded irrlicht I tried an example

it seems the library Irrlicht.a provided isn't compatible with my compiler.
so I tried to recompile the library
as indicated in the Makefile, I ran mingw32-make win32
and then I get another error :
<builtin>: recipe for target 'zlib/adler32.o' failed
mingw32-make: *** [zlib/adler32.o] Error 1
can anybody help (note that I don't want to use vc++)
the problem was the Irrlicht.a provided was a 32bit library where i was compiling for 64bits, so I had to use a 32bit compiler instead.
