Subject: [GCC-XML] Setting relative path for included user defined header
	files in C++ code
Message-ID: <CAOeebD10K8+-z1hMFMa=8wT0JC=OzO_s41BFegRFt3eqGc-Szw@mail.gmail.com>

Hello gccxml -mailing-list,
I am trying to parse a C++ file which includes many user defined
header files. GCCXML is not able to read the location of header files
included in the code. Is there a way I can change the base path which
when appended with the path mentioned in "#include <pathname>" lines
written in the code gives the path of the directory containing the
header files.

I tried to work around this problem by specifying the paths of all the
header files in a text file and then using the following command :

--gccxml-gcc-options textfilename

But this creates a problem in case there is a long chain of
dependencies as I would have to specify the paths of files included in
the header files as well. Is there a way to solve this problem?

In this regard gccxml is just like a compiler: all include directories
must be specified with -I options just as if you were trying to compile
the source file.

Thanks a lot Brad. I am facing two more issues.
1) gccxml seems to be parsing a lot of code which is not in the current C++
file. I guess it is parsing the included header files. Is there a way to
avoid this?

2) I need to dump the function bodies to xml as well. Does the patch
offered by Daniel J Lauk succesfully dump function bodies to xml?

No.  The parser *is* a compiler.  It needs the full translation
unit just like any other compiler.  However, you can use
-fxml-start=some_decl to dump only a subset of the parsed
declarations to xml.

This is not supported by gccxml.

Perhaps but it has not been maintained with the rest of gccxml
so I do not know if it would still work.

I suggest looking at Clang instead:

 http://clang.llvm.org/docs/Tooling.html
