similar to: [LLVMdev] Compiling libc++ from within llvm (3.1)

Hi Ashok, I created a new Ubuntu 12.04 virtual machine and followed directions except that I know use your cmake command instead of configure, and I got the error below. Any help is very much appreciated. $ /home/ubuntu/bin/bin/clang++ -I /home/ubuntu/bin/include/ tutorial1.cpp In file included from tutorial1.cpp:5: In file included from /home/ubuntu/bin/include/llvm/Support/raw_ostream.h:17:

Hi, In another post I was trying to find out how to use libc++ instead of libstdc++ when compiling llvm/clang. I couldnt find the a way to tell cmake to do that. So I switched to using configure to compile llvm/clang. But now I find that the artifacts produced are different. Here are the issues I see: - configure doesnt seem to respect '--prefix' option, it just puts

Looks like your make/install is incomplete wrt clang. I follow the instuctions for checking out the sources but build using cmake instead of configure: > cmake -G ""Unix Makefiles" -DLLVM_TARGETS_TO_BUILD="X86" -DCMAKE_BUILD_TYPE="Release" -DCMAKE_INSTALL_PREFIX="../bin" ../llvm > make install This builds and installs llvm+clang in the bin

OK.  Thanks.  I now get the following error (which appears to be a problem w/ the tutorial itself?): $ /home/ubuntu/bin/bin/clang++ -I /home/ubuntu/bin/include/  -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS tutorial1.cpp/tmp/tutorial1-LQ71fW.o: In function `main': tutorial1.cpp:(.text+0x42): undefined reference to `llvm::outs()' tutorial1.cpp:(.text+0x72): undefined reference to

Hi Ashok, The documentation suggests that I put clang inside of llvm/tools and so I have two separate include directories.  I tried both of them and neither worked: $ clang++ -I llvm/include tutorial1.cpp  In file included from tutorial1.cpp:5: In file included from llvm/include/llvm/Support/raw_ostream.h:17: In file included from llvm/include/llvm/ADT/StringRef.h:13:

Add -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS to your compilation flag.

Hi All, I'm using LLVM/Clang 3.1 release. I first compiled llvm/clang using GCC per the instructions on the web with cmake. I then compiled libc++ per the instructions on the web. I then tried to compile llvm/clang with previously compiled clang and libc++ using "-std=c++0x -stdlib=libc++" flags. But the compilation fails at: > [ 58%] Building CXX object

Hi Ashok, As I mentioned in my earlier e-mail, my /usr/local/include does not have clang/ or clang-c/. I'm unable to do a make or make install in the Clang build directory.  How do I fix this?

The "make install" should collect everything into your <install path>. The <install path> will then have bin, lib and include dirs.

Hi All, I've compiled Qt 4.7.3 (yes, its an older version but 4.8 has a few issues) with clang + libc++. When I compile one of my resource files using Qt's moc, it reports: > ...x86_64-centos-linux-clang-libcxx/include/QtCore/QObjec:0: Warning: No relevant classes found. No output generated. I traced it to the presence of libc++ include path in the compilation: >

You will need to link to the LLVM/clang libraries. To get the correct flags, you can run: ./llvm-config --ldflags --libs and use the flags reported. On 7/10/2012 11:35 AM, NY Knicks Fan wrote: > OK.

Use the -I<install path>/include . This directory <install path>/include should look something like: clang/ clang-c/ llvm/ llvm-c/ HTH ashok On 7/9/2012 3:15 PM, NY Knicks Fan wrote: > I downloaded the 3.1 LLVM and Clang sources. > > I followed the directions at: http://clang.llvm.org/get_started.html > > I am able to use Clang to compile stuff, but I could

You need to link in the libclang* as well.

I downloaded the 3.1 LLVM and Clang sources. I followed the directions at: http://clang.llvm.org/get_started.html I am able to use Clang to compile stuff, but I could already do that with GCC. I'm trying to use Clang for parsing code, but I can't even get started. Can you tell me how to "include the installed location of  clang/llvm headers directories in your include path"?

Thanks Dimitry. That worked. I see some warnings in my compilations: > Building CXX object lib/Support/CMakeFiles/LLVMSupport.dir/IntEqClasses.cpp.o > [ 2%] clang-3: warning: argument unused during compilation: '-nostdinc++' > Building CXX object lib/Support/CMakeFiles/LLVMSupport.dir/IntrusiveRefCntPtr.cpp.o > clang-3: warning: argument unused during compilation:
