Before llvm4, both major and minor version updates of llvm were regularly
|
||
|
|
breaking API. Because of that, the libLLVM library was named in following
|
||
|
|
format: libLLVM-${major}-${minor}.so
|
||
|
|
|
||
|
|
(https://bugs.llvm.org/show_bug.cgi?id=25059)
|
||
|
|
(https://reviews.llvm.org/D13841)
|
||
|
|
|
||
|
|
The package containing this library was called libLLVM${major}_${minor} which
|
||
|
|
follows our guidelines.
|
||
|
|
|
||
|
|
Since llvm4, llvm decided to follow semantic versioning and only break API if
|
||
|
|
the major version was increased. In addition they do not intend to ever have
|
||
|
|
minor version other than 0.
|
||
|
|
(http://blog.llvm.org/2016/12/llvms-new-versioning-scheme.html)
|
||
|
|
|
||
|
|
The package was renamed to libLLVM${major}, which no longer follows the naming
|
||
|
|
guidelines, but since the package contained multiple libraries, it was not
|
||
|
|
detected.
|
||
|
|
|
||
|
|
Since bnc#1049703 the libLLVM${major} package contains only the
|
||
|
|
libLLVM-${major}-${minor}.so library and no others. This triggers the
|
||
|
|
shlib-policy-name-error check in our packaging system.
|
||
|
|
|
||
|
|
Because the reasons for using the libLLVM-${major}-${minor}.so format are no
|
||
|
|
longer valid, lets revert back to libLLVM.so.${major}.${minor}.${version}
|
||
|
|
format. That way the package name matches our guidelines.
|
||
|
|
|
||
|
|
With llvm18, the minor version is now always 1 for releases, and upstream
|
||
|
|
decided to rename the library to libLLVM.so.${major}.${minor}, but keep the
|
||
|
|
old name as symbolic link for backwards compatibility. That is of course
|
||
|
|
not relevant for us.
