Add -D__STDC_LIMIT_MACROS -D__STDC_CONSTANT_MACROS to your compilation flag.

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.

I follow the instuctions for checking out the sources but build using cmake instead of configure: > cmake -G ""Unix Makefiles" -DLLVMTARGETSTOBUILD="X86" -DCMAKEBUILDTYPE="Release" -DCMAKEINSTALLPREFIX="../bin" ../llvm > make install This builds and installs llvm+clang in the bin directory one level above llvm. I tried using configure earlier but had some problems. ashok On 7/9/2012 5:32 PM, NY Knicks Fan wrote: > 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? > > Thanks! > > ------------------------------------------------------------------------ > From: Ashok Nalkund <ashoknn at qualcomm.com_ _<mailto:ashoknn at qualcomm.com>> > To: NY Knicks Fan <nyknicksfan92009 at yahoo.com_ _<mailto:nyknicksfan92009 at yahoo.com>>; "llvmdev at cs.uiuc.edu <mailto:llvmdev at cs.uiuc.edu>" > <llvmdev at cs.uiuc.edu <mailto:llvmdev at cs.uiuc.edu>> > Sent: Monday, July 9, 2012 3:30 PM > Subject: Re: [LLVMdev] Unable to do even basic Clang tutorial > > Use the -I/include . > > This directory /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/getstarted.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 ofclang/llvm > > headers directories in your include path"? > > > > Thanks! > > > > > > ------------------------------------------------------------------------ > > From: Ashok Nalkund <ashoknn at qualcomm.com_ _<mailto:ashoknn at qualcomm.com> > <mailto:ashoknn at qualcomm.com <mailto:ashoknn at qualcomm.com>>> > > To: NY Knicks Fan <nyknicksfan92009 at yahoo.com_ _<mailto:nyknicksfan92009 at yahoo.com> > <mailto:nyknicksfan92009 at yahoo.com <mailto:nyknicksfan92009 at yahoo.com>>> > > Cc: Chad Rosier <mcrosier at apple.com <mailto:mcrosier at apple.com> <mailto:mcrosier at apple.com <mailto:mcrosier at apple.com>>>; > "llvmdev at cs.uiuc.edu <mailto:llvmdev at cs.uiuc.edu> <mailto:llvmdev at cs.uiuc.edu <mailto:llvmdev at cs.uiuc.edu>>" > > <llvmdev at cs.uiuc.edu <mailto:llvmdev at cs.uiuc.edu> <mailto:llvmdev at cs.uiuc.edu <mailto:llvmdev at cs.uiuc.edu>>> > > Sent: Monday, July 9, 2012 2:39 PM > > Subject: Re: [LLVMdev] Unable to do even basic Clang tutorial > > > > On 7/9/2012 1:42 PM, Chad Rosier wrote: > > > Have you looked here: http://clang.llvm.org/getstarted.html > > > > > > Chad > > > > > > > > > On Jul 9, 2012, at 11:33 AM, NY Knicks Fan wrote: > > > > > >> I'm trying to do the tutorials at: > > >> > > >> https://github.com/loarabia/Clang-tu...i/TutorialOrig > > >> <https://github.com/loarabia/Clang-tutorial/wiki/TutorialOrig> > > >> > > >> and I can't even do the first tutorial.
