    <p>I'm trying to get Clang to work on Windows, to eventually develop with Qt Creator to see if it's a viable alternative to Visual Studio.</p> <p>I got LLVM and Clang 3.2 (SVN Revision 163238) to compile using <a href="http://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Automated%20Builds/" rel="noreferrer">MinGW w64</a> (mingw-w64-bin_i686-mingw_20111220.zip) and also pointed to gcc's C++ header directories by adding <code>AddMinGWCPlusPlusIncludePaths("D:/Code/mingw/lib/gcc", "x86_64-w64-mingw32", "4.7.0");</code> to <code>clang/lib/Frontend/InitHeaderSearch.cpp</code>, although I think that might not be the most up-to-date method. Anyway, Clang seems to find most of those headers.</p> <p>However, when compiling a simple Hello World:</p> <pre><code>#include &lt;iostream&gt; int main(int argc, char* argv[]) { std::cout &lt;&lt; "test\n"; return 0; } </code></pre> <p>using <code>clang++ main.cpp</code> I get this error:</p> <pre><code>In file included from main.cpp:1: In file included from D:/Code/mingw/lib/gcc/x86_64-w64-ming32/4.7.0./include/c++\iostream:39: In file included from D:/Code/mingw/lib/gcc/x86_64-w64-ming32/4.7.0./include/c++\ostream:39: In file included from D:/Code/mingw/lib/gcc/x86_64-w64-ming32/4.7.0./include/c++\ios:39: In file included from D:/Code/mingw/lib/gcc/x86_64-w64-ming32/4.7.0./include/c++\iosfwd:41: In file included from D:/Code/mingw/lib/gcc/x86_64-w64-ming32/4.7.0./include/c++\postypes.h:41: D:/Code/mingw/lib/gcc/x86_64-w64-ming32/4.7.0./include/c++\cwchar:45:10: fatal error: 'wchar.h' file not found </code></pre> <p>So, Clang apparently finds several C++ headers including <code>iostream</code> but fails to find <code>wchar.h</code>. Turns out that <code>wchar.h</code> is located in <code>.../include/c++\tr1</code> where Clang doesn't look for it. Moving those TR1 headers up one directory doesn't help either.</p> <p>What did I do wrong here? Is the gcc C++ library not compatible with Clang, since apparently it still hasn't integrated some TR1 libraries into the standard? Where could I get a compatible C++11 library for Clang (for Windows!)?</p>

    1. CO`wchar.h` should come from your C library. It doesn't necessarily need to be shipped with Clang.

    2. COI've tried long to work clang on windows but it seems a no way...for now you cab use mingw (4.7.2) or vc++2012 express

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
