RFE: Portable OpenSSH

[Christopher Linn]

what am doing is to link the libz and openssl stuff static, because
of moving target issues, and then let solaris do what it wants with 
it's own libs, for exactly the reasons that darren moffat enumerates.

if you are going to run solaris, then get used to trusted code linking
shared libs, simple as that.  sun's recent offerings are getting very
good at this, though it means you must keep up with the patches  ;*)

interestingly, in zlib-1.1.3 you must *ask* configure to build shared
libs, otherwise it just builds libz.a ... why is it an "external
runtime dependancy" for you, dan?

when building openssh, i use a directory structure like

	/someplace/openssh/5.6			for solaris 2.6
	/someplace/openssh/5.6/{include,lib}	openssl, zlib, libwrap
	/someplace/openssh/5.6/work		for building stuff

i install static libs and headers as above, building them in .../work.
then i build openssh (in .../work) with CPPFLAGS set with my include
area and LDFLAGS set with my lib area:

	MYINCLUDES=/someplace/openssh/5.6/include
	MYLIBS=/someplace/openssh/5.6/lib
	...
	CPPFLAGS="-I$MYINCLUDES -I$MYINCLUDES/openssl \
	CFLAGS="whatever" \
	LDFLAGS="-L$MYLIBS -R$MYLIBS" \
	./configure \
	--configure-options...

the reason i use the env based flags is that i found that the
--cflags/--cppflags/--ldflags options to configure would always put MY
stuff AFTER /usr/local stuff (grr, and what do you think is in
/usr/local... shared libs!  ;*)

ldd on the binaries lists only the native solaris shared libs.
i am using native sun compilers for all this.
