<br>
i have been compiling clang for months without problems, until about last week. Since then I can't compile.<br>
<br>
usually delete CMakeCache.txt then run<br>
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_C_COMPILER=/usr/local/bin/clang -DCMAKE_CXX_COMPILER=/usr/local/bin/clang++ -DCMAKE_CXX_FLAGS="-std=c++11 -stdlib=libc++" -DCMAKE_SHARED_LINKER_FLAGS="-std=c++11 -stdlib=libc++" -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_WERROR=OFF -DLLVM_BUILD_TOOLS=ON -DLLVM_BUILD_EXAMPLES=OFF -DCLANG_BUILD_EXAMPLES=OFF -DLLVM_APPEND_VC_REV=ON /Users/Mani/Development/Projects/llvm/source<br>
ln -s $PWD/compile_commands.json /Users/Mani/Development/Projects/llvm/source<br>
<br>
and then run<br>
make -j10 ENABLE_OPTIMIZED=1 DISABLE_ASSERTIONS=1<br>
<br>
Here is what i get.<br>

Anybody know what going on?<br></blockquote><div><br></div><div>You've got a problem with compiling AddressSanitizer runtime: it incorrectly defines "dirent" structure (normally it comes from /usr/include/sys/dirent.h).</div>
<div>1) Which OS X version do you use?</div><div>2) What is the value of __DARWIN_64_BIT_INO_T on your system? (you may check it by including sys/cdefs.h and looking at the value of this definition).</div><div> <br></div>
<div>Note that if you're not interested in ASan, you may just build clang as follows:</div><div>"make -j10 ENABLE_OPTIMIZED=1 DISABLE_ASSERTIONS=1 clang"</div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
