如何获取gdb使用Eclipse CDT在Windows下（无法找到源代码） [英] How to get gdb working with Eclipse CDT under windows (fails to find source code)

问题描述

我安装了cygwin（最新的1.7.xx？），然后安装了eclipse cdt（Juno）。

当我试图建立一个hello world项目时，尽管eclipse标识cygwin安装，它没有工作。

所以我手动添加c：\cygwin\bin到路径，发现所有的可执行文件cygwin，包括g ++，make ld等。

现在，eclipse可以构建项目，但是在调试时，gdb启动，找不到源代码。它声称找不到：

/cygdrive/c/users/me/workspace/test1/test1.cc
。
即使这正是它在哪里。就像cygwin的目录系统不工作一样。

我可以手动加载源代码：

c ：\users\me\workspace\test1\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\再做一次。
如何指示eclipse / cygwin组合正确找到源代码？

或者，Mingw更容易吗？我遇到类似的问题eclipse看到mingw是有，但构建失败，因为它没有找到可执行文件。

解决方案

这是我如何使它的工作。

1. 我转到窗口==>首选项==> C / C ++ ==>调试==>源查找路径


2. 我添加路径映射：项目源


3. 在左侧，我放置Cygwin期望的路径，即\home\MyName\projects，右侧我放了Windows路径，即C：\cygwin\home\MyName\projects

它找到源文件很好。

I installed cygwin (the latest 1.7.xx?), and then installed eclipse cdt (Juno).

When I tried to build a hello world project, despite eclipse identifying that cygwin was installed, it didn't work.

So I manually added c:\cygwin\bin to the path, which found all the executables in cygwin, including g++, make ld, etc.

Now, eclipse can build the project, but when debugging, gdb starts up and can't find the source code. It claims that it can't find:

/cygdrive/c/users/me/workspace/test1/test1.cc . even though that's exactly where it is. It's as though cygwin's directory system doesn't work.

I can manually load the source from:

c:\users\me\workspace\test1\test1.cc

and the debugger works, but the next time I start a new project, I have to do it again. How do you instruct the eclipse/cygwin combo to correctly find source code?

Alternatively, is Mingw any easier? I have experienced similar problems with eclipse seeing that mingw is there, but build failing because it doesn't find the executable.

解决方案

Here is how I made it work.

1. I goto Window ==> Preferences ==> C/C++ ==> Debug ==> Source Lookup Path
2. I Add a Path Mapping: Project Source
3. On the left side I put the path that Cygwin expects, i.e. \home\MyName\projects and on the right side I put the Windows path, i.e. C:\cygwin\home\MyName\projects

Then when I debug it finds the source file fine.
