[Bug 1242300] Re: Clang cannot locate standard header files
In Ubuntu 14.04 LTS I installed Clang 3.7 after adding new official repository from http://llvm.org/apt/ Then based on this thread: http://askubuntu.com/questions/428198/getting-installing-gcc-g-4-9-on-ubuntu/456849#456849 I tried backport the latest packages I add ppa repository: sudo add-apt-repository ppa:ubuntu-toolchain-r/test Refreshed my repositories: sudo apt-get update And finally installed (ideally) latest toolchain: sudo apt-get install g++-5 Everything works fine when compiling as follows: clang++-3.7 -std=c++14 main.cpp What I left unresolved is using choose of default compiler.

[Bug 1242300] Re: Clang cannot locate standard header files
I was just bitten by this. I tried to upgrade from clang-3.4 to clang-3.5, and was unable to compile anything because the standard headers were not found. I then downgraded back to clang-3.4, and was surprised to find that to be broken as well. Since at that point I was stuck, I plowed on until I found a solution. The issue seems related to the fact that gcc-4.9 exists at this point in time, but g++-4.9 does not. I think this means it only affects those who have partially upgraded to gcc-4.9 (the C compiler, but not the C++ compiler). Clang is searching for the standard C++ header in directories that don't exist and not finding them. There also seem to be issues where Clang is searching only for /usr/include/c++ without adding an appropriate version number. One fix is to add symlinks until Clang can find the files it's looking for. The currently searched header directories can be found with: clang++ -E -x c++ - -v /dev/null Assuming a test file 'file.cpp' that includes a failing header, you can see where g++ is successfully finding a header (and Clang is failing) like this: strace -f g++ file.cpp -std=gnu++11 -o file.o 21 | grep header strace -f clang++ file.cpp -std=gnu++11 -o file.o 21 | grep header There are several ways of helping Clang to find the headers it is looking for, all of varying degree of likelihood to break other things. I decided the path of least harm was to create symlinks like this: $ ls -l /usr/include/c++/ lrwxrwxrwx 1 root root 3 Dec 20 15:50 backward - 4.8 lrwxrwxrwx 1 root root37 Dec 20 15:56 x86_64-linux-gnu - /usr/include/x86_64-linux-gnu/c++/4.8 Once you solve the issue of finding header files, you then won't be able to find libstdc++.so. I fixed that with this: sudo ln -s /usr/lib/gcc/x86_64-linux-gnu/4.8 /usr/local/lib/x86_64-linux-gnu Now that I've done this, both clang-3.4 and clang-3.5 will work, although not simultaneously because Ubuntu supports multiple versions of GCC but not of Clang. Note that this is just an ugly workaround for a bug that should be fixed by Ubuntu. Once this is fixed, these steps will be unnecessary, and possibly hazardous. Personally, I think that Ubuntu should support having multiple versions of Clang installed, and rather than deinstalling one version to install another. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1242300 Title: Clang cannot locate standard header files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/llvm-defaults/+bug/1242300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1242300] Re: Clang cannot locate standard header files
For the 3.5 LLVM toolchain it seems that the symlink /usr/lib/clang/3.5/include erroneously points to ../../llvm-3.4/lib/clang/3.5/include, but should instead point to ../../llvm-3.5/lib/clang/3.5/include The workaround (of course) is to manually correct the symlink. For the 3.4 toolchain the /usr/lib/clang/3.4/include doesn't exist at all. I have not tried LLVM 3.4 on Ubuntu so I don't know if createing a symlink to ../../llvm-3.4/lib/clang/3.4/include will fix the problem, but it does seem likely. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1242300 Title: Clang cannot locate standard header files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/llvm-defaults/+bug/1242300/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
