Dev-C++使用点滴

    Dev-C++是一个在Windows下用使用gcc编译器的IDE,我目前使用的版本是4.9.8.0版,下载地址为http://www.c-view.org/soft/devcpp/downloads/devcpp4980.exe,可以在它自己的主页http://bloodshed.net/或http://sourceforge.net/projects/dev-cpp/中找到关于Dev-C++的更多信息.

1.在Dev-C++中调试程序
    用Dev-C++编写C++项目时,如果用菜单"Debug/Debug"调试时,系统会提示"Your project does not have debugging information, do you want to enable debugging and rebuild your project?",此时即使选"Yes"也还是不能调试.要在"Project/Class Brower"窗口中(通过View/Project/Class Brower调出该窗口),然后选中项目按右键,选"Project Options"在"Compiler"页中选"Linker"项,将其中的"Generate debugging information"设为"Yes".此时再重新链接一次程序,就可以调试了.

2.观察变量
    在调试中观察变量值时,string类型的变量如果先加入到了Debug窗口中,单步走时是不会自动刷新的,所以需要将已经加入的变量删除后再添加才能看到新的值,但对int这样的变量是可以自动刷新的.

3.恢复c,cpp等文件与VC的关联
    由于安装程序有bug,所以不管选不选于C,C++文件关联,安装完成后C,Cpp,H,rc等都会自动与Dev-C++关联,如果在"Tools/Emvironment Options"的"File Associ..."页中将与c,cpp,h,rc的关联去除,也不能恢复本来与VC的关联,而且在资源管理器中通过"工具/文件夹选项"的文件类型中,也看不到c,cpp,h,rc了.此时可以将下列内容放入一个扩展名为reg的文件中,导入到注册表中.注意,下面例子中,Visual Studio 6安装在F:/Program Files/Microsoft Visual Studio目录下,所以要根据具体情况修改路径.

然后在"工具/文件夹选项"的文件类型中,删除c,cpp,h,rc类型,再重新建立,建立类型时按下"高级"按钮,选择"关联的文件类型"
c选C Source file
cpp选C++ Source file
h选C Header file
rc选Resource Template
