| # |
| # Purpose |
| # |
| # To test the code dependencies on individual curves in each test suite. This |
| # is a verification step to ensure we don't ship test suites that do not work |
| # for some build options. |
| # |
| # The process is: |
| # for each possible curve |
| # build the library and test suites with the curve disabled |
| # execute the test suites |
| # |
| # And any test suite with the wrong dependencies will fail. |
| # |
| # Usage: tests/scripts/curves.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. |
