Original question: ----------------- [..] What I am attempting to do is compiling openssh-2.2.0p1 on a C200 running 11.0 64bit. During configure, ld exits from building a test program stating: /usr/ccs/bin/ld: /opt/openssl/lib/libcrypto.a: Not a valid library (invalid magic number). Possibly a 64-bit PA archive library (Mismatched ABI). [..] Solution: -------- Many thanks to Albert C. Smith who pointed me in the right direction. After he told me to have an eye on cc rather than on ld I made my way to a working openssh. The following suggestion may be extremely quick n? dirty since I?m new to both openssh as well as 64bit HP-UX. Anyways, it works for me ;) Most of all, only ssh is running, sshd has *serious* problems for which I?ll contact it?s authors. o get the latest openssh *portable* source from www.openssh.org o have recent zlib and openssl libraries already installed o in configure, lines 1612 and 1646 (as of 2.2.0p1) change LIBS="-lz $LIBS" to LIBS="$LIBS -lz" and in lines 1705 and 1739 change LIBS="-lnsl $LIBS" to LIBS="$LIBS -lnsl" o run CC="cc +DA2.0W" CFLAGS=-I/opt/zlib/include CPPFLAGS="-L/usr/lib/pa20_64\ -L/usr/lib -L/opt/zlib/lib -L/opt/openssl/lib" LIBS=$CPPFLAGS \ ./configure --without-pam --prefix=/opt/openssh --with-pid-dir=/var/run \ --with-ipv4-default --with-ssl-dir=/opt/openssl/lib && make && make \ install Kind regards, Volker -- V.
