Problems to build a cross compiler under Linux

["karim" <bernardet dot karim at wanadoo dot fr>]

Hello !

I want to have under linux a compiler which produces binaries for windows
(with cygwin). So I try cross compiling. I use the script below to do that
and I use binutils-20021107-2, gcc-3.2-3, newlib-1.9.0 and cygwin-1.3.15-2
for the headers. The compilation was successfull (but I had to move some
headers files) but when I try to compile a simple hello.c :
/home/karimb/cross/build/bin/i686-cygwin32-gcc hello.c, I got this error :

./../lib/gcc-lib/i686-cygwin32/3.2/../../../../i686-cygwin32/bin/ld: ne peut
trouver -lcygwin
collect2: ld a retourné 1 code d'état d'exécution
(sorry for the french language)

so it can t find a cygwin library ...

Thanks for your help ...

Karim
