Package: llvm-3.8-dev
Version: 1:3.8-2
Severity: normal
Dear Maintainer,
Issues similar to those in bug #785931 have returned in the 3.8 package.
When a CMake-based project does
find_package(LLVM)
on Debian one gets
CMake Error at /usr/share/llvm-3.8/cmake/LLVMConfig.cmake:178 (include):
include could not find load file:
/usr/share/llvm/cmake/LLVMExports.cmake
The reason is explained in this thread on the llvm mailing list:
http://thread.gmane.org/gmane.comp.compilers.llvm.cvs/255502/focus=255724
Basically upstream LLVM made changes during 3.8 development to make their
CMake packaging files relocatable by computing locations relative to one
another. However, Debian's packaging changes these relative locations by
moving things around after installation. Therefore the wrong locations
are computed.
Debian packaging must be taught to patch LLVMConfig.cmake to specify
absolute locations of LLVM_INSTALL_PREFIX, LLVM_CMAKE_DIR, etc. based
on where Debian puts them.
Note that the 'castxml' package requires LLVM/Clang CMake packaging files
to build. Therefore building that package against a llvm-*-dev package
(and libclang-*-dev) will reveal such problems.
