Package: libc++-10-dev Version: 1:10.0.0-4 Severity: normal
It is not the end of the world, but it does impose some limitations: # apt install libc++-dev The following additional packages will be installed: libc++-9-dev libc++1-9 libc++abi1-9 Suggested packages: clang The following packages will be REMOVED: libc++-10-dev libc++1-10 libc++abi-10-dev libc++abi1-10 The following NEW packages will be installed: libc++-9-dev libc++-dev libc++1-9 libc++abi1-9 # The headers are already in versioned locations, and clang from what I have seen with clang: $ clang++-10 -v -march=native -O3 -fcoroutines-ts -std=c++2a -stdlib=libc++ -lc++abi nanotest.cpp -o nanotest clang version 10.0.0-4 ignoring nonexistent directory "/include" #include "..." search starts here: #include <...> search starts here: /usr/lib/llvm-10/bin/../include/c++/v1 /usr/local/include /usr/lib/llvm-10/lib/clang/10.0.0/include /usr/include/x86_64-linux-gnu /usr/include ... $ $ dpkg -L libc++-10-dev:amd64 | grep include | head /usr/lib/llvm-10/include /usr/lib/llvm-10/include/c++ /usr/lib/llvm-10/include/c++/v1 /usr/lib/llvm-10/include/c++/v1/__bit_reference /usr/lib/llvm-10/include/c++/v1/__bsd_locale_defaults.h /usr/lib/llvm-10/include/c++/v1/__bsd_locale_fallbacks.h /usr/lib/llvm-10/include/c++/v1/__config /usr/lib/llvm-10/include/c++/v1/__cxxabi_config.h /usr/lib/llvm-10/include/c++/v1/__debug /usr/lib/llvm-10/include/c++/v1/__errc ... /usr/lib/llvm-10/lib /usr/lib/llvm-10/lib/libc++.a /usr/lib/llvm-10/lib/libc++.so ... $ So I would assume it it should be easily possible, and clang already default to correct includes. I do not know if it also defaults to the correct linker paths tho. Because packages do have libc++.so symlinks, that can throw it off, unless user manually select what they want: $ dpkg -L libc++-10-dev:amd64 | grep usr/lib/x86.*/libc++.* /usr/lib/x86_64-linux-gnu/libc++.a /usr/lib/x86_64-linux-gnu/libc++.so $ $ ls -lh /usr/lib/x86_64-linux-gnu/libc++.* lrwxrwxrwx 1 root root 23 Apr 10 08:27 /usr/lib/x86_64-linux-gnu/libc++.a -> ../llvm-10/lib/libc++.a lrwxrwxrwx 1 root root 24 Apr 10 08:27 /usr/lib/x86_64-linux-gnu/libc++.so -> ../llvm-10/lib/libc++.so lrwxrwxrwx 1 root root 13 Apr 10 08:27 /usr/lib/x86_64-linux-gnu/libc++.so.1 -> libc++.so.1.0 lrwxrwxrwx 1 root root 28 Apr 10 08:27 /usr/lib/x86_64-linux-gnu/libc++.so.1.0 -> ../llvm-10/lib/libc++.so.1.0 $ But that seems easily fixable. -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.2.0-3-amd64 (SMP w/32 CPU cores) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages libc++-10-dev depends on: ii libc++1-10 1:10.0.0-4 libc++-10-dev recommends no packages. libc++-10-dev suggests no packages. -- no debconf information
