| 13 | # 2002-07-27: Initial release. |
| 14 | # 2002-08-04: Added public domain notice. |
| 15 | # 2003-06-24: Incorporated readme, set library paths. First cvs version. |
| 16 | # |
| 17 | # "OpenSSL headers do not match your library" are usually caused by |
| 18 | # OpenSSH's configure picking up an older version of OpenSSL headers |
| 19 | # or libraries. You can use the following # procedure to help identify |
| 20 | # the cause. |
| 21 | # |
| 22 | # The output of configure will tell you the versions of the OpenSSL |
| 23 | # headers and libraries that were picked up, for example: |
| 24 | # |
| 25 | # checking OpenSSL header version... 90604f (OpenSSL 0.9.6d 9 May 2002) |
| 26 | # checking OpenSSL library version... 90602f (OpenSSL 0.9.6b [engine] 9 Jul 2001) |
| 27 | # checking whether OpenSSL's headers match the library... no |
| 28 | # configure: error: Your OpenSSL headers do not match your library |
| 29 | # |
| 30 | # Now run findssl.sh. This should identify the headers and libraries |
| 31 | # present and their versions. You should be able to identify the |
| 32 | # libraries and headers used and adjust your CFLAGS or remove incorrect |
| 33 | # versions. The output will show OpenSSL's internal version identifier |
| 34 | # and should look something like: |
| 35 | |
| 36 | # $ ./findssl.sh |

| 54 | # In this example, I gave configure no extra flags, so it's picking up |
| 55 | # the OpenSSL header from /usr/include/openssl (90604f) and the library |
| 56 | # from /usr/lib/ (90602f). |
