[gentoo-dev] Breaking changes in dev-libs/msgpack-5.0.0

[Marek Szuba]

Dear everyone,



Having not been given any love for a long time, we have now got in the 

tree a version of dev-libs/msgpack newer than 3.3.0 - namely 5.0.0. Yes, 

we have managed to skip the entire major version 4 (yay?)! Anyway, the 

version in question introduces at least two breaking changes:



  - since 4.0.0, the (header-only) C++ library is no longer bundled with 

the C one. As a consequence, a new(ish) package dev-cpp/msgpack-cxx has 

been introduced and  >=dev-libs/msgpack-5.0.0 no longer provide 

IUSE="boost cxx";



  - since 5.0.0 CMake modules for both the C and the C++ variant of 

msgpack have different names, which might break cmake-based revdeps 

which have not been updated accordingly.



In light of the above, both dev-cpp/msgpack-cxx and 

 >=dev-libs/msgpack-5.0.0 are currently masked in order to give the 

maintainers of msgpack devreps ample time to test compatibility with the 

new versions. They will, however, be unmasked on the 3rd of March unless 

major problems are encountered with the revdep update. There is a 

tracker bug "msgpack-5" which can be used to group related issues.



On behalf of the Vim project,
