#
# 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.
