It return "not found" when include another header.

[naive231]

I build a .clang_complete in my project dir. My sources are in the same dir :

$project_root\ --- src01.cpp --- src02.cpp --- src01.h --- src02.h --- .clang_complete

.clang_complete has those content: -ID:\work\project\suffering_buster\code\project -ID:\svn\windows\tool\MinGW\include -ID:\svn\windows\tool\MinGW\lib\gcc\mingw32\4.5.2\include -ID:\svn\windows\tool\MinGW\lib\gcc\mingw32\4.5.2\include\c++

Then, given an example code like this: #include <vector> std:: <- It can show completion list. #include <src01.h> std:: <- It can't show completion list.

WHY ?

[Silex]

probably that src01.h contains invalid code that prevents clang from working.

[naive231]

No! It isn't correct ! I build .clang_complete and it contains all information of completion of my symbol, it should find correct information despite I include any other nonsense headers. I am not compile any program, none any checking "error" should affect the search result. If symbol is in .clang_complete, it should be found after I use this plugin to find it.

[Silex]

No, your source is required to be compilable. If you include a header that doesn't compile, clang will stop there.

See https://github.com/Rip-Rip/clang_complete/blob/master/doc/clang_complete.txt?#L205-207

[naive231]

compilable? You mean I should include all stuff that can pass compilation of my src01.cpp or src02.cpp ? I remember that I had try it before,it fails,too. But that's ok, I'll write another small project to test your solution. :)

[Silex]

Not really, what I meant is that in order to do completion, clang tries to compile your .cpp file and if it fails to do so then completion will not work.

I upload an image about my files usage and put remarks. https://docs.google.com/open?id=0By2IiDMUu0gCN096TUxjTF9iZ2s

test.cpp at left view has two std:: code, upper can show completion menu,but lower can't.

.clang_complete in the center of view. I include lots of header. Of course, It contains .

Content of at the right side show its context of all includes, I believe all headers should be included by .clang_complete.

Well. test.cpp don't have any my project files any more, I just include some standard stuff like vector or string. But if I include , clang_complete always fail. If I include

I can't tell differences about and the other standard stuff ?

[Silex]

The 2nd std:: cannot work because the first one creates a compile error. If you write std::string global_string; instead of the first one then the second one should work. The first one works because there's no errors before that point.

Anyway intermixing header inclusion with code is generally a bad idea, so avoid it.

[naive231]

Oops,sorry for your misunderstanding. ;) My explanation about those two std:: are not exist at the same time, I just write them in codes for screen shot. If I just write the upper one std:: only, it can bring correct complete menu on, lower one std:: can't. So my question is that why can't I include would result to clang_complete fail ?

[Silex]

I have no clue, except that you intermix code with header inclusion which usually no one does.

@Rip-Rip: any idea?

Does a file with just #include and an empty main, compile with clang? If it doesn't then look at the error, I'm guessing that one of the included headers contains some C++11 that is not supported by clang (if you're not using clang 3.1, you should try with it).

Other than that, I see that you're using header from gcc 4.5.2, and others from gcc 4.6.2, it shouldn't be a problem, but who knows…

[naive231]

I'm using clang v3.2. If contains C++11 context really.... I can't use clang any more? It is standard library header and I wouldn't spend any time to modify its content ever. Final question is different version of header from different gcc version. I install MinGW from official site in that mean time, so I can't control its context,too. It shouldn't be a problem.

[xavierd]

If is using C++11, it may not work with clang: the set of C++ features supported by clang and gcc are different.

http://clang.llvm.org/cxx_status.html for clang, http://gcc.gnu.org/projects/cxx0x.html for gcc.

You didn't answer my first question: Does a file with just #include and an empty main, compile with clang?

[naive231]

Yes, my code is just a empty main only, nothing more.
