Package: libclang1-3.9 Version: 1:3.9-2 Severity: normal Hi,
libclang1-3.9, a library package, depends on libobjc-6-dev and libstdc++-6-dev. Those in turn pull in quite a number of dependencies themselves. As a consequence, installing doxygen, which links against libclang1-3.9, results in: # apt install doxygen Reading package lists... Done Building dependency tree Reading state information... Done The following additional packages will be installed: libasan3 libatomic1 libc-dev-bin libc6-dev libcilkrts5 libclang1-3.9 libedit2 libgcc-6-dev libgomp1 libitm1 libllvm3.9 liblsan0 libmpx2 libobjc-6-dev libobjc4 libquadmath0 libstdc++-6-dev libtsan0 libubsan0 linux-libc-dev manpages manpages-dev Suggested packages: doxygen-latex doxygen-doc doxygen-gui graphviz glibc-doc libstdc++-6-doc man-browser The following NEW packages will be installed: doxygen libasan3 libatomic1 libc-dev-bin libc6-dev libcilkrts5 libclang1-3.9 libedit2 libgcc-6-dev libgomp1 libitm1 libllvm3.9 liblsan0 libmpx2 libobjc-6-dev libobjc4 libquadmath0 libstdc++-6-dev libtsan0 libubsan0 linux-libc-dev manpages manpages-dev 0 upgraded, 23 newly installed, 0 to remove and 0 not upgraded. Need to get 33.3 MB of archives. After this operation, 145 MB of additional disk space will be used. That's quite a lot and unexpected if you only want doxygen. I looked at the llvm-toolchain changelog, but didn't find a justification why the library package needs to depend on those -dev packages. Could those dependencies be dropped or moved to another package? It seems odd to have a library package pull in dev packages.
