emacs cedet语义与Qt4如何配置

2023年9月8日 297次阅读

我在X86_64-pc-gnu-
linux(ubuntu 10.04)上使用emacs 23.1.1,并按照着名的链接
http://alexott.net/en/writings/emacs-devenv/EmacsCedet.html将所有配置添加到.emacs.

但它甚至不能做基本的工作.我的设置或配置一定有问题.

如果我试图让它显示成员函数,它就无法找到.
[自动完成使用clang作为解析器.那么解析器语义使用什么？ ]

这是源文件：

#include <QApplication>
#include <QPushButton>
#include <QString>
int main (int argc, char ** argv)
{
QApplication app (argc, argv);
QPushButton hello ("Hello, World!");
hello.resize (100, 30);
hello.show ();
QString id("hi");
return app.exec ();
}

Unable to find datatype for: “class QPushButton hello ()”.
Declared type is: “class QPushButton {}”
Raw data type is: (“QPushButton” type (:type “class”) nil nil)

Semantic could not find this data type in any of its global tables.

Semantic locates datatypes through either the local scope, or the global
typecache.

Local Scope Information:
* Tag Class Constraint against SCOPE: (type)
* No known parents in current scope.
* No known symbols currently in scope.
* No known symbols declared locally.
Semantic creates and maintains a type cache for each buffer.
If the type is a global type, then it should appear in they typecache.
To examine the typecache, type:

M-x semanticdb-typecache-dump RET [ Do It ]

Current typecache Statistics:
0 types global in this file
0 types from includes.

If the datatype is not in the typecache, then your include
path may be incorrect.

Include Path Summary:

This file’s project include search is handled by the EDE object:
Buffer Target: #ede-cpp-root-target /home/mike/project/shared/>
Buffer Project: #ede-cpp-root-project Test>
Backup Locator: #ede-locate-base Loc>

The system include path is:

06002

Include Summary: /home/mike/project/shared/test-qt-semantic.cpp

test-qt-semantic.cpp contains 3 includes.
Unknown Includes: 0
Unparsed Includes: 0
Parsed Includes: 3
No unknown includes.

最佳答案 它在底部说：

It seems, that this approach will not work in fresh CEDET – I’m working on fix

然后在评论中他说：

It seems, that CEDET wasn’t compiled properly. Please, take CEDET from CVS and compile according instructions

所以我认为你应该再次编译和构建它然后它应该工作 – 但我没有尝试过.我只是建议它,因为这是文章所说的.
