Public bug reported: In debian/rules, it tries to determine the clang version by parsing /usr/bin/clang.
CLANG_VER := $(shell realpath /usr/bin/clang | sed -e 's/.*llvm-\([0-9]\+\).*/\1/') However the Ubuntu patch uses a specific clang version, which missing /usr/bin/clang symlink, causing the script failed to work. As seen from the build log, dh_auto_configure -- -DCCLS_VERSION=0.20190823-3ubuntu3 -DCLANG_RESOURCE_DIR=/usr/include/clang//usr/bin/clang The clang resource dir is wrong. I don't how to write the debian/rules better. If you have ideas, please tell me, and I will include it in Debian. For this specific case for Ubuntu, you can set CLANG_VER = 8 in debian/rules. If you want to build ccls with default clang, which is clang-9, just add lldb to build-depends. Then ccls can build without problem. The reason is https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=941082 which is a bug in llvm. ** Affects: ccls (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845233 Title: configured with wrong clang resource directory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ccls/+bug/1845233/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
