I am trying to install winex on my ximian (RH9), ./configure runs fine, make depend runs fine, when i start make, it returns following errors:

reetype -lz -lm
/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status
make[2]: *** [libgdi32.so] Error 1
make[2]: Leaving directory `/opt/winex/dlls/gdi'
make[1]: *** [gdi/libgdi32.so] Error 2
make[1]: Leaving directory `/opt/winex/dlls'
make: *** [dlls] Error 2

Does it mean I am lacking the libgdi32.so library? or something else. Can anyone help me. I got winex through cvx.

Thanks!
