这似乎是一个错误。错误报告链接：https://bugzilla.gnome.org/show_bug.cgi?id=731363
我正在使用 Doxygen 1.8.7 和 Graphviz 2.38。我配置了 Doxygen 来扫描更大的项目并生成 HTML 页面的文档。
现在，我想要/需要那里的呼叫者/被叫图，并且我将可能与之相关的每个标志设置为“是”。但结果仍然相同：对于 4 个方法，会生成被调用者/调用者图，但不会为其他方法生成。
我检查了 Doxygen 的日志文件，发现了 4 个这样的条目：
Generating caller graph for function [...]对于其他所有课程，只有
Generating docs for compound [...]...有没有办法获取 doxygen 拒绝生成函数调用者图的更详细日志/原因？
我的 doxygen 配置：

编辑
似乎只有当调用者/被调用方法位于同一个类内时才会生成调用图。然而，接口似乎有不同的行为。
编辑2
好吧，我创建了一个测试项目，乍一看，它似乎证实了我在第一次编辑中所写的内容。这是测试代码：
public class Class1
{
public void SomePublicMethod()
{
Refresh();
}
public void SomeOtherPublicMethod()
{
SomePublicMethod();
}
private void SomePrivateMethod()
{
SomeOtherPublicMethod();
Refresh();
}
private static void Refresh()
{
}
}
public class Class2
{
private Class1 test2;
public void ConstructingClass1()
{
Class1 test = new Class1();
test.SomeOtherPublicMethod();
test2 = new Class1();
}
public void CallingAllPublicsOfClass1()
{
test2.SomeOtherPublicMethod();
test2.SomePublicMethod();
}
}
创建一个 .NET 4 或 4.5 解决方案，创建 2 个类文件并将上述代码复制并粘贴到其中（应该可以编译）。现在让 doxygen 运行它。它将为 Class1 中的所有方法创建调用者/被调用图，不包括 Class2 中的所有方法。这意味着您不会看到
SomeOtherPublicMethodClass2.ConstructingClass1如果更改为 class2，则根本不会有任何调用者/被叫图。
编辑3
你也可以将两个类放在同一个文件中，但它仍然不会生成图表。
它在这次提交中解决了。 https://github.com/doxygen/doxygen/commit/7edbf2b2e705eccc0d99cce86149228473bc7f3e
所以下一个版本可能会包含此错误修复。
Doxygen 的代码解析器（负责代码浏览器、交叉引用列表和调用图）并不完美，因此它可能在某个地方丢失了轨道。如果没有代码示例，很难说出位置和原因。
如果你想要准确解析可以尝试设置
CLANG_ASSISTED_PARSING = YES
CLANG_OPTIONS = <compiler options>
然后 doxygen 将使用 clang 编译器前端来解析代码。您可能会收到关于缺失内容的更好警告，并且需要进行调整
CLANG_OPTIONS对于仍然遇到某些或许多函数未生成调用图的人，例如我今天遇到的情况，您可能需要将
DOT_GRAPH_MAX_NODES50200如果在另一个函数中调用的根节点（例如：所有函数）超过此
DOT_GRAPH_MAX_NODESdoxygen -g Doxyfile标签可用于设置图表中显示的最大节点数。如果图中的节点数量大于该值，doxygen 将截断该图，这通过将节点表示为红色框来可视化。请注意，doxygen 如果图中根节点的直接子节点数量已经大于DOT_GRAPH_MAX_NODES，那么该图根本不会显示。DOT_GRAPH_MAX_NODES
您还需要确保启用必要的“提取”设置，以便能够从所有这些类型的事物中提取（生成）图表：
EXTRACT_ALL = YES
EXTRACT_PRIVATE = YES
EXTRACT_PRIV_VIRTUAL = YES
EXTRACT_PACKAGE = YES
EXTRACT_STATIC = YES
EXTRACT_LOCAL_CLASSES = YES # is already YES by default
EXTRACT_LOCAL_METHODS = YES # only affects Objective-C code
EXTRACT_ANON_NSPACES = YES
RESOLVE_UNNAMED_PARAMS = YES # is already YES by default
您需要启用
dotHAVE_DOT = YES
CALL_GRAPH = YES
CALLER_GRAPH = YES
