如何可视化包含/点到另一个C结构的图？ [英] How to visualise a graph of C structs that contain / point to one another?
问题描述
我使用Ubuntu 10.04，并研究内核对象的编程。
I am using Ubuntu 10.04, and studying programming of kernel objects.
我也碰到过，我有困难，读一些相当复杂的结构，所以我想我会尝试找到一些工具，可以帮助我想像他们。
I have come across some rather complicated structs which I have difficulties reading, so I thought I'd try to find some tool that can help me visualise them.
我唯一能找到到目前为止 VCG ，其中有一个 C结构可视化例子，它看起来像这样的：
Only thing I could find so far is VCG, which has a C Struct Visualization Example, which looks like this:
这看起来像我想使用。
which looks like something I'd like to use.
第一件事，就是打包为Ubuntu的最后一个VCG是 VCG（1.30debian-6）在hardy < /一> - 但.deb包可以被下载并安装在Ubuntu清醒没有问题。
First thing, is that the last VCG packaged for Ubuntu is vcg (1.30debian-6) in hardy - but the .deb package can be downloaded and installed in Ubuntu Lucid without problems.
但是，似乎这个包只是一个VCG的浏览器的（类似的 vcgviewer ，我猜）。该 vcgviewer 页注：
However, it seems this package is only a VCG viewer (similar to vcgviewer, I'd guess). The vcgviewer page notes:
To generate compiler graph data with newest gcc compilers use:
gcc -g -da -dv -fdump-tree-original-raw -fdump-tree-all-all
所以，显然我不得不使用这些开关与 GCC沿在编译，生成从C源.vcg图形文件。
So, apparently I'd have to use those switches along with gcc while compiling, to generate .vcg graph files from the C source.
但问题是，我要建一个内核模块，只引用了Linux头 - 因为我尽量避免像我可以整个内核的重新编译。而现在看来，只要我尝试使用 -fdump树-... 这方面（内核模块）的交换机， GCC 要开始编译内核的休息呢！ （，显然失败了，在这两个编辑和生成.vcg图形 - 因为我没有内核源代码，只有头文件的）
The problem, however, is that I'm building a kernel module, which only references the Linux headers - as I try to avoid as much as I can the recompilation of entire kernel. And it seems, as soon as I try to use -fdump-tree-... switches in that context (kernel module), gcc wants to start compiling the rest of the kernel too! (and obviously fails, in both compilation and generation of .vcg graphs - as I don't have the kernel sources, only headers)
所以，我的问题是 - 是有一个工具，这将产生.vcg结构或.DOT图 - 简单地用一个纯文本的头文件作为输入？ （那就不必解决所有的依赖关系 - 不仅仅是那些在同一个目录中的头文件的）
So my question is - is there a tool, that would produce .vcg or .dot graphs of structs - simply using a plain text header file as input? (it would not have to resolve all dependencies - simply those in header files in same directory)
编辑：它实际上是不适合我，重要的是，后端特别.vcg或.DOT，我提到他们只是因为我发现他们为止;任何形式的软件，将允许类似的结构可视化，无论后台的，我们都是欢迎的
it is actually not that important for me that the backend is .vcg or .dot in particular, I mentioned them just because I've found them so far; any sort of software that would allow similar struct visualization, regardless of backend, is welcome :)
PS：需要注意的是，如果你不希望使用VCG观众观看.vcg图表，您可以将.vcg格式转换为.DOT格式，并使用的graphviz 而不是为可视化。什么工作对我来说是使用图易 - search.cpan.org 为 perl的 - 这第一次拿到打包在Ubuntu与小牛版，为的 libgraph易-perl的（然而，.deb文件可以 - 再 - 是清醒<下载并安装没有问题/ em>的）。 libgraph易-perl的安装了图易脚本，然后允许做的东西，如：
PS: Note that if you do not want to use VCG viewers for viewing .vcg graphs, you can convert the .vcg format to a .dot format, and use graphviz instead for the visualisation. What worked for me is to use graph-easy - search.cpan.org for perl - which first got packaged in Ubuntu with Maverick edition, as libgraph-easy-perl (however, the .deb file can - again - be downloaded and installed without problems in Lucid). libgraph-easy-perl installs a graph-easy script, which then allows to do stuff like:
graph-easy test.vcg --as_dot | dot -Tpng -o test.vcg.png
另请参阅 [graphviz的利益] VCG文件和迭戈Novillo - 回复：找不到VCG观众另一VCG-来点脚本（，不幸的是，没有为我<工作/ EM>）。
See also "[graphviz-interest] VCG files" and "Diego Novillo - Re: can't find VCG viewer" for another vcg-to-dot script (which, unfortunately, didn't work for me).
推荐答案
我有好经验用的该任务doxygen的。它的目的是创造出来的文档注释的源文件，但它已经可以给你很多东西不注释，包括各种图表。
Doxygen的使用点的图形创建。
I have had good experiences with using doxygen for that task. It is designed to create documentation out of annotated source files, but it can already give you a lot of things without the annotations, including various graphs. Doxygen uses dot for the graph creation.
