我花了很多时间来配置和测试 Qt4 的 emacs 语义和自动完成功能。由于间接包含，我发现这些甚至无法解析或找到 Qt4 包含文件。例如，QString> include qstring.h (include ../../src/tools/qstring.h, mingw) 我总是得到“Wrong type argument: stringp, nil”（在 Linux 或 Mingw 上试试）我没有了解 Lisp。你能帮我解决这个问题吗？非常感谢！

调试跟踪如下：

 Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  call-process(nil nil #<buffer *clang-output*> nil "-cc1" "-fsyntax-only" "-I~/project/qt481-mingw/include" "-I~/project/qt481-mingw/include/Qt" "-I~/project/qt481-mingw/include/QtCore" "-I~/project/qt481-mingw/include/QtGui" "-code-completion-at" "c:/Users/ygao/project/tests/test-qt-semantic.cpp:13:8" "c:/Users/ygao/project/tests/test-qt-semantic.cpp")

  apply(call-process nil nil #<buffer *clang-output*> nil ("-cc1" "-fsyntax-only" "-I~/project/qt481-mingw/include" "-I~/project/qt481-mingw/include/Qt" "-I~/project/qt481-mingw/include/QtCore" "-I~/project/qt481-mingw/include/QtGui" "-code-completion-at" "c:/Users/ygao/project/tests/test-qt-semantic.cpp:13:8" "c:/Users/ygao/project/tests/test-qt-semantic.cpp"))

从堆栈跟踪来看，似乎ac-clang-executable是零。尝试M-x customize-option RET ac-clang-executable将其设置为clang二进制文件的路径。
