Package: clang Version: 2.9-14 Severity: normal Hello,
this is mostly a dup of 594820 (that I reported last year), but I was asked to report it as a separate bug: $ cat f.cc #include <fenv.h> $ clang++ -P -E f.cc namespace std { typedef long unsigned int size_t; typedef long int ptrdiff_t; } $ (compare with g++ which outputs the real content) This happens because the include path contains /usr/include/c++/4.6 then /usr/include/c++/4.5 and later /usr/include, which breaks the #include_next mechanism of fenv.h. clang needs to decide (either at build-time or runtime) on one of 4.5 or 4.6 but it shouldn't have both. ignoring nonexistent directory "/usr/include/c++/4.6//x86_64-linux-gnu/64" ignoring nonexistent directory "/usr/bin/../lib/clang/2.9/include" ignoring duplicate directory "/usr/include/c++/4.6" ignoring duplicate directory "/usr/include/c++/4.6//backward" ignoring duplicate directory "/usr/include/x86_64-linux-gnu" #include "..." search starts here: #include <...> search starts here: /usr/include/c++/4.6 /usr/include/c++/4.6//backward /usr/include/c++/4.6//x86_64-linux-gnu /usr/include/c++/4.5 /usr/include/c++/4.5/x86_64-linux-gnu /usr/include/c++/4.5/backward /usr/local/include /usr/include/x86_64-linux-gnu /usr/lib/gcc/x86_64-linux-gnu/4.6/include /usr/lib/gcc/x86_64-linux-gnu/4.6/include-fixed /usr/lib/gcc/x86_64-linux-gnu/4.5/include /usr/lib/gcc/x86_64-linux-gnu/4.5/include-fixed /usr/include (it is a bit surprising that /usr/include/x86_64-linux-gnu ends up before /usr/lib/gcc/x86_64-linux-gnu/*/*, but that shouldn't matter) -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (500, 'testing'), (500, 'stable'), (50, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 3.0.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages clang depends on: ii libc6 2.13-21 ii libffi5 3.0.10-1 ii libgcc1 1:4.6.1-15 ii libllvm2.9 2.9+dfsg-3 ii libstdc++6 4.6.1-15 ii libstdc++6-4.6-dev 4.6.1-15 Versions of packages clang recommends: ii llvm-2.9-dev 2.9+dfsg-3 ii python 2.7.2-8 clang suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
