This directory contains a minimal example for how to build mlkem-native with support for all 3 security levels MLKEM-512, MLKEM-768, and MLKEM-1024, and so that level-independent code is shared. In this example, only the C-backend of mlkem-native is used.
The library is built 3 times in different build directories build/mlkem{512,768,1024}. For the MLKEM-512 build, we set
MLK_CONFIG_MULTILEVEL_WITH_SHARED to force the inclusion of all level-independent code in the
MLKEM512-build. For MLKEM-768 and MLKEM-1024, we set MLK_CONFIG_MULTILEVEL_NO_SHARED to not include any
level-independent code. Finally, we use the common namespace prefix mlkem as MLK_CONFIG_NAMESPACE_PREFIX for all three
builds; the suffix 512/768/1024 will be added to level-dependent functions automatically.
Build this example with make build, run with make run.
