+#!/bin/sh
+#
+# findssl.sh
+# Search for all instances of OpenSSL headers and libraries
+# and print their versions.
+# Intended to help diagnose OpenSSH's "OpenSSL headers do not
+# match your library" errors.
+#
+# Written by Darren Tucker (dtucker at zip dot com dot au)
+# This file is placed in the public domain.
+#
+# Release history:
+# 2002-07-27: Initial release.
+# 2002-08-04: Added public domain notice.
+# 2003-06-24: Incorporated readme, set library paths. First cvs version.
+# 2004-12-13: Add traps to cleanup temp files, from Amarendra Godbole.
+#
+# "OpenSSL headers do not match your library" are usually caused by
+# OpenSSH's configure picking up an older version of OpenSSL headers
+# or libraries. You can use the following # procedure to help identify
+# the cause.
+#
+# The output of configure will tell you the versions of the OpenSSL
+# headers and libraries that were picked up, for example:
+#
+# checking OpenSSL header version... 90604f (OpenSSL 0.9.6d 9 May 2002)
+# checking OpenSSL library version... 90602f (OpenSSL 0.9.6b [engine] 9 Jul 2001)
+# checking whether OpenSSL's headers match the library... no
+# configure: error: Your OpenSSL headers do not match your library
+#
+# Now run findssl.sh. This should identify the headers and libraries
+# present and their versions. You should be able to identify the
+# libraries and headers used and adjust your CFLAGS or remove incorrect
+# versions. The output will show OpenSSL's internal version identifier
+# and should look something like:
+
+# $ ./findssl.sh
+# Searching for OpenSSL header files.
+# 0x0090604fL /usr/include/openssl/opensslv.h
+# 0x0090604fL /usr/local/ssl/include/openssl/opensslv.h
+#
+# Searching for OpenSSL shared library files.
+# 0x0090602fL /lib/libcrypto.so.0.9.6b
+# 0x0090602fL /lib/libcrypto.so.2
+# 0x0090581fL /usr/lib/libcrypto.so.0
+# 0x0090602fL /usr/lib/libcrypto.so
+# 0x0090581fL /usr/lib/libcrypto.so.0.9.5a
+# 0x0090600fL /usr/lib/libcrypto.so.0.9.6
+# 0x0090600fL /usr/lib/libcrypto.so.1
+#
+# Searching for OpenSSL static library files.
+# 0x0090602fL /usr/lib/libcrypto.a
+# 0x0090604fL /usr/local/ssl/lib/libcrypto.a
+#
+# In this example, I gave configure no extra flags, so it's picking up
+# the OpenSSL header from /usr/include/openssl (90604f) and the library
+# from /usr/lib/ (90602f).
+
+#
+# Adjust these to suit your compiler.
+# You may also need to set the *LIB*PATH environment variables if
+# DEFAULT_LIBPATH is not correct for your system.
