[Jan Matis]

Hallo ,
 i wanted to compile a ssh 2.0.13 on a sun's solaris 7 
./configure worked good 
but make made something strange :

In file included from deflate.h:16,
                 from deflate.c:52: 
zutil.h:20:  string.h: No such file or directory
zutil.h:21: stdlib.h: No such file or directory
zutil.h:26: errno.h: No such file or directory


I konw that ssh 1.2.26 works on solaris 2.6
now i have solaris 7 
and i need ssh 1.2.x + 2.0.x 
 
Can anybody help me how to do it (or gimme some url please :))

                                        Thanks,
                                                Jan Matis
