I followed your instructions, but make still fails:
gcc -o ssh ssh.o readconf.o clientloop.o sshtty.o sshconnect.o
sshconnect1.o sshconnect2.o readpass.o -L. -Lopenbsd-compat/ -L/usr/ssl
-lssh -lopenbsd-compat -lcrypto -lutil -lz -lcrypt -ldl
/usr/bin/ld: cannot find -ldl
*** Error code 1
Stop in /usr/home/pauls/Downloads/sara-6.0.7d/src/sssh.
*** Error code 1
I put AC_SEARCH_LIBS(dlopen,dl) at the end of configure.in, just before
AC_OUTPUT(Makefile). There was no mention of ldl in Makefile.in.
Any suggestions?
