| # Purpose |
| # |
| # To test the code dependencies on individual key exchanges in the SSL module. |
| # is a verification step to ensure we don't ship SSL code that do not work |
| # for some build options. |
| # |
| # The process is: |
| # for each possible key exchange |
| # build the library with all but that key exchange disabled |
| # |
| # Usage: tests/scripts/key-exchanges.pl |
| # |
| # This script should be executed from the root of the project directory. |
| # |
| # For best effect, run either with cmake disabled, or cmake enabled in a mode |
| # that includes -Werror. |
