llvm dev - Jun 2012 - [LLVMdev] Extracting an AST to Graphviz using Clang

Just in case another person comes to get stuck on this on Mac OS:

http://web.mit.edu/mfloyd/www/computing/mac/gv/

This link explains the process on getting gv installed since Xaw3d
dependency even has a 'error' (actually missing few parameters) on a
line
that prevents code compilation that needs to be fixed before configuring
and make it works.

-- I have gv installed now and my bash console can recognize the 'gv'
and
'dot' as specified on llvm manual, from my previous email I believe I
compiled on debug mode and my bash does recognize 'clang' bash now but
still I get:

clang -cc1 -ast-view smd.c

*Stmt::viewAST is only available in debug builds on systems with Graphviz
or gv!*

What am I missing? :(

Thanks,

Carlos Andrade

You need to run the clang from the build directory. Something like
./Debug+Asserts/bin/clang

Hi Joey,

Still the same message.

I am running it from llvm-2.9/Debug/bin/clang -cc1 -ast-view ~/smd.c

Is this where you were referring to?

Best,
