- # 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.
