clang++

I just to change the include search path order (I believe). I'd like to change the include search path. Especially, I need /usr/local/include first. But it doesn't change because of duplicate. How can I change it? I suppose there's default setting, because paths I don't specify appears. Like /usr/include/c++/4.2.1 , /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../lib/clang/6.0/include "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang" -cc1 -triple x86_64-apple-macosx10.10.0 -emit-obj -mrelax-all -disable-free

I'm using clang to try and parse (with the C++ API) some C++ files and make all the case - break pairs use a specific style. Example : **Original** switch(...) { case 1: { <code> }break; case 2: { <code> break; } } **After replacement** switch(...) { case 1: { <code> break; } case 2: { <code> break; } } What I have so far does exactly what I want if the code parts don't contain any macros. My question is: does clang treat expanded ( if I do a dump of a problematic statement it will show the expanded version ) macros differently? if so how can I get this to work? Additional info that may help:

Clang has a nice page describing the project status w.r.t. C++1z/C++17 feature support (and C++11 and C++14, it's the same page). g++ has a page regarding C++14 features , but I couldn't find anything about C++17/C++1z. Is that being worked on but just not present on the web? For version 5.0? As of today, gcc's C++1z language support is tracked on: https://gcc.gnu.org/projects/cxx1z.html . For the C++1z status of libstdc++, see https://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.201z . There is some support already; The following two summaries are oriented on Clang's list:

I had been erroneously using this command, which failed at the link step: $ clang -std=c++11 -stdlib=libc++ myInputFile.cpp Can anyone explain why clang provides a C++ language option, and why it fails to link? Why don't the options -x c++ or -std=c++11 accomplish the same thing as clang++ ? Thanks! Technically, neither of the programs named clang or clang++ is a compiler: they are both drivers that analyze the input arguments and determine what compilers/assemblers/linkers to invoke on what files with what command line arguments. The only difference between the two is that clang links against

I just installed clang++3.6 on my Ubuntu machine, but can't set it as the default c++ compiler. sudo update-alternatives --config c++ tells me that There is only one alternative in link group c++ (providing /usr/bin/c++): /usr/bin/g++ Nothing to configure. and clang++ doesn't show up in sudo update-alternatives --query c++ either (which was to be expected). But the compiler definitely works: which clang++-3.6 /usr/bin/clang++-3.6 My OS version is Ubuntu 14.04.1 LTS. What do I have to do to make update-alternatives include clang++3.6? Note: I previously used clang3.4, but removed it since it

As far as I understand, Visual Studio 2015 is shipped with clang. First I though this was only for Android and iOS apps, but according to this article it should also be possible to use the clang++ frontend for Windows programs. However, I can't find the according option. So could you please explain to me, how I can change the used compiler to clang in a c++ project (in VS2015 RC Community Edition). Starting with VS2015 Update 1 you can install the "Clang with Microsoft CodeGen" template via the New Project window, browse to Installed -> Templates -> Visual C++ -> Cross Platform. You will then

Is it possible to get Travis CI working with Clang that is capable of C++11? (I want Clang, not GCC, I already have GCC 4.8 working in Travis CI.) It appears that the version that is there pre-installed is not C++11 capable. All my attempts at installing any newer version end up failing because of this : In file included from /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../include/c++/4.8/bits/move.h:57: /usr/lib/gcc/x86_64-linux-gnu/4.8/../../../../include/c++/4.8/type_traits:269:39: error: use of undeclared identifier '__float128' struct __is_floating_point_helper<__float128> I have seen the
