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.
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.
