corrosion-rs/corrosion v0.2.0

on GitHub

Breaking changes

• Removed the integrator build script (#156).
  The build script provided by corrosion (for rust code that links in foreign code) is no longer necessary,
  so users can just remove the dependency.

Deprecations

• Direct usage of the following target properties has been deprecated. The names of the custom properties are
  no longer considered part of the public API and may change in the future. Instead, please use the functions
  provided by corrosion. Internally different property names are used depending on the CMake version.
  • CORROSION_FEATURES, CORROSION_ALL_FEATURES, CORROSION_NO_DEFAULT_FEATURES. Instead please use
    corrosion_set_features(). See the updated Readme for details.
  • CORROSION_ENVIRONMENT_VARIABLES. Please use corrosion_set_env_vars() instead.
  • CORROSION_USE_HOST_BUILD. Please use corrosion_set_hostbuild() instead.
• The Minimum CMake version will likely be increased for the next major release. At the very least we want to drop
  support for CMake 3.12, but requiring CMake 3.16 or even 3.18 is also on the table. If you are using a CMake version
  that would be no longer supported by corrosion, please comment on issue
  #168, so that we can gauge the number of affected users.

New features

• Add NO_STD option to corrosion_import_crate (#154).
• Remove the requirement of building the Rust based generator crate for CMake >= 3.19. This makes using corrosion as
  a subdirectory as fast as the installed version (since everything is done in CMake).
  (#131, #161)
  If you do choose to install Corrosion, then by default the old Generator is still compiled and installed, so you can
  fall back to using it in case you use multiple cmake versions on the same machine for different projects.

Fixes

• Fix Corrosion on MacOS 11 and 12 (#167 and
  #164).
• Improve robustness of parsing the LLVM version (exported in Rust_LLVM_VERSION). It now also works for
  Rust versions, where the LLVM version is reported as MAJOR.MINOR. (#148)
• Fix a bug which occurred when Corrosion was added multiple times via add_subdirectory()
  (#143).
• Set CC_<target_triple_undercore> and CXX_<target_triple_undercore> environment variables for the invocation of
  cargo build to the compilers selected by CMake (if any)
  (#138 and #161).
  This should ensure that C dependencies built in cargo buildscripts via cc-rs
  use the same compiler as CMake built dependencies. Users can override the compiler by specifying the higher
  priority environment variable variants with dashes instead of underscores (See cc-rs documentation for details).
• Fix Ninja-Multiconfig Generator support for CMake versions >= 3.20. Previous CMake versions are missing a feature,
  which prevents us from supporting the Ninja-Multiconfig generator. (#137)
