I think there now is: https://packages.debian.org/search?keywords=llvm&searchon=names§ion=all&suite=stretch-backports Package llvm-6.0-dev stretch-backports (devel): Modular compiler and toolchain technologies, libraries and headers 1:6.0-1~bpo9+1: amd64 It's a recent addition: llvm-toolchain-6.0 (1:6.0-1~bpo9+1) stretch-backports; urgency=medium * Team upload * Rebuild for stretch-backports. -- Anton Gladky <gl...@debian.org> Mon, 12 Mar 2018 18:58:43 +0100 Otherwise I think LLVM has a repo with the necessary bits: http://apt.llvm.org/ But if it's not this, I think we're going to have to indeed build LLVM. Without proper debugging symbols it's going to be hard to figure this out otherwise. FWIW, I build it with: mkdir -p ~/build/llvm/debug/vpath cd ~/build/llvm/debug/vpath cmake -G Ninja ~/src/llvm/ -DCMAKE_INSTALL_PREFIX=/home/andres/build/llvm/debug/install -DBUILD_SHARED_LIBS=true -DLLVM_TARGETS_TO_BUILD='X86;BPF' -DLLVM_CCACHE_BUILD=true ninja -j8 install I suspect you'd need to replace X86 with AArch64 (BPF isn't needed, that's for stuff unrelated to PG). > If that turns out to be it I guess we'd need to figure out how to > detect an LLVM with bits missing hand handle it more gracefully? Yea :/. Greetings, Andres Freund
