wut/CHANGELOG.md

wut 1.0.0-beta9

Breaking changes

• coreinit's exit is no longer defined in <coreinit/exit.h>. Please use <stdlib.h> instead, which pulls in newlib's exit.
• RPL import sections (.fimport_coreinit etc.) are now garbage-collected when using wut-tools 1.1.0 or above (required). Code relying on weak links to Cafe functions may exhibit different behaviour.
• snd_core and snd_user are no longer linked, due to naming conflicts with sndcore2 and snduser2. wut has never shipped headers for these libraries, but if you are using them, please switch to sndcore2 and snduser2.
• Changes to CMake's linker flags may cause existing build trees to fail. Please delete any old build files and re-run CMake.
• Two new symbols, __rpx_start and __rpl_start, are now used internally by the toolchain, while _start is now undefined. As usual, applications are strongly discouraged from prefixing any symbol with two underscores, in order to avoid conflicts of this type.

Deprecations

• WUT_ROOT should no longer be defined in the user's environment, and will be set to $DEVKITPRO/wut internally. CMake lists and makefiles that use $WUT_ROOT/share to find wut.mk or wut.toolchain.cmake should be changed to $DEVKITPRO/wut/share.
• All of wut's static libraries (-lcoreinit, -lwhb, etc.) have been merged into a single libwut, which gets automatically linked in for all builds. While empty static libraries have been provided for CMake builds to ease the transition, these will be removed eventually. Applications should remove the build flags to link any of wut's libraries.
• Similarly, wut's build configuration options (devoptab, wutmalloc, newlib) are now integrated into libwut. For CMake builds, the wut_enable_* macros will now log a deprecation warning, and should be removed as soon as possible.
• Use of wut.mk as a build system is now deprecated. Applications should move to wut_rules and devkitPro-style makefiles, such as those in the samples. wut.mk will not be updated further, and will be removed in a future release.

Other changes

• Builds refactored: wut now uses Makefiles to build itself, as well as providing a devkitPro-style wut_rules file - see the samples/make folder. The cmake samples are now in samples/cmake.
• A new linking feature, __rplwrap, was added to help deal with conflicts between newlib's and Cafe's functions. Because of this, wut 1.0.0-beta9 requires wut-tools 1.1.0 or newer.
• Using rplwrap, newlib's exit is now correctly chained with coreinit's - calls like atexit should work; whether calling exit or just returning from main. Applications using coreinit's _Exit are encouraged to migrate to a normal exit call.
• A new header file, <coreinit/codegen.h>, has been added and documented for OSCodegen functionality.
