# 2002-07-27: Initial release.
|
|
# 2002-08-04: Added public domain notice.
|
|
# 2003-06-24: Incorporated readme, set library paths. First cvs version.
|
|
#
|
|
# "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

|
|
# 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.
