Dears, I am new to this list, and hope this question is pertinent to this mailing list. I have been trying to use Clang to extract an AST from my source code, but without success when attempting to do so with Graphviz. I created a thread on Stackoverflow recently in hope any could help me [1], but the question is actually pretty simple. I keep getting Stmt::viewAST is only available in debug builds on systems with Graphviz or gv! alongside the code that is output despite having graphviz added to the path and having it installed on my machine. dot works fine from my console, but I have no 'gv' like it is suggested on the documentation (you can find how I attempted that and the versions on the stack link better formatted than on this email). The command I am running on my console is: ./clang -cc1 -ast-view smd.c My graphviz version is 2.28 and my clang version is 2.9 (for a couple of reasons I need to make it work for this version). http://stackoverflow.com/questions/10962845/stmtviewast-is-only-available-in-debug-builds-on-systems-with-graphviz-or-gv I also heard xml output was discontinued, but I still see the option from cc1 to output in such format without any warning message on 2.9 (although no apparent output is given in that case), why is that?

[LLVMdev] Extracting an AST to Graphviz using Clang
Hi Carlos,> I am new to this list, and hope this question is pertinent to this mailing > list.Welcome!> Stmt::viewAST is only available in debug builds on systems with Graphviz or > gv!You need to actually build Clang in debug mode for this particular method to be available, which is very likely why you're seeing this error. I don't think that Clang builds shipped with Xcode (for example) are built in debug mode.

Hi Alex, Would you recommend any specific link in respect on how to compile in debug mode? I downloaded the Mac OS version on the website so I did not compile anything. I am sort of a rookie on bash but I should be able to figure my way around this. Also, is there any particular reason why this functionality is only available on debug mode? Thank you so much for the fast reply, was driving me nuts!
