Damien Millera8e06ce2003-11-21 23:48:55 +110020# "OpenSSL headers do not match your library" are usually caused by
Darren Tuckera0472e02003-06-24 20:22:09 +100021# OpenSSH's configure picking up an older version of OpenSSL headers
22# or libraries. You can use the following # procedure to help identify
23# the cause.
Damien Millera8e06ce2003-11-21 23:48:55 +110024#
Darren Tuckera0472e02003-06-24 20:22:09 +100025# The output of configure will tell you the versions of the OpenSSL
26# headers and libraries that were picked up, for example:
Damien Millera8e06ce2003-11-21 23:48:55 +110027#
Darren Tuckera0472e02003-06-24 20:22:09 +100028# checking OpenSSL header version... 90604f (OpenSSL 0.9.6d 9 May 2002)
29# checking OpenSSL library version... 90602f (OpenSSL 0.9.6b [engine] 9 Jul 2001)
30# checking whether OpenSSL's headers match the library... no
31# configure: error: Your OpenSSL headers do not match your library

Darren Tuckera0472e02003-06-24 20:22:09 +100033# Now run findssl.sh. This should identify the headers and libraries
34# present and their versions. You should be able to identify the
35# libraries and headers used and adjust your CFLAGS or remove incorrect
36# versions. The output will show OpenSSL's internal version identifier
37# and should look something like:
