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

Hi Joey,

I think there is still something missing.

I ignored the -j as you mentioned and saw on the documentation that to
compile on debug mode I could do so using:

$./configure --disable-optimized

As a result by the end I compiled llvm2.9 I got:

llvm[0]: ***** Completed Debug Build
llvm[0]: ***** Note: Debug build can be 10 times slower than an
llvm[0]: ***** optimized build. Use make ENABLE_OPTIMIZED=1 to
llvm[0]: ***** make an optimized build. Alternatively you can
llvm[0]: ***** configure with --enable-optimized.


Which lead me to believe I end up getting what you suggested on debug mode.
I also put clang 2.9 inside /tools/clang (renamed the clang-2-9) so that
the configure could notice it and ran $make test inside the clang folder
after it.

Still I executed $ ./clang -cc1 -ast-view smd.c only to get

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

Mixed up with the output and nothing being show on graphviz. What am I
missing? Again, I have graphviz but I don't think I have gv and I am
running an OS X Lion 10.7.4 (latest version).

Thanks,

Just to add one more thing. I have been trying to install the gv on my mac
os but I have not been successful either. The gv build requires xaw3d (
http://directory.fsf.org/wiki/Xaw3d ) which apparently has not been updated
for quite few years and the download is not even available anymore.

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,
