How to get gdb working with Eclipse CDT under windows (fails to find source code)
提问by Dov
I installed cygwin (the latest 1.7.xx?), and then installed eclipse cdt (Juno).
我安装了cygwin（最新的1.7.xx？），然后安装了eclipse cdt（Juno）。
When I tried to build a hello world project, despite eclipse identifying that cygwin was installed, it didn't work.
当我尝试构建一个 hello world 项目时，尽管 eclipse 识别出安装了 cygwin，但它没有工作。
So I manually added c:\cygwin\bin to the path, which found all the executables in cygwin, including g++, make ld, etc.
所以我手动添加了c:\cygwin\bin到路径中，找到了cygwin中的所有可执行文件，包括g++、make ld等。
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:
现在eclipse可以构建项目了，但是调试的时候gdb启动了，找不到源码。它声称找不到：
/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.
/cygdrive/c/users/me/workspace/test1/test1.cc 。即使那正是它所在的位置。就好像 cygwin 的目录系统不起作用一样。
I can manually load the source from:
我可以从以下位置手动加载源：
c:\users\me\workspace\test1\test1.cc
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?
并且调试器可以工作，但是下次我开始一个新项目时，我必须再做一次。您如何指示 eclipse/cygwin 组合正确查找源代码？
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.
或者，Mingw 更容易吗？我在 eclipse 中遇到了类似的问题，看到 mingw 存在，但是构建失败，因为它没有找到可执行文件。

Here is how I made it work.
这是我如何使它工作。
- I goto Window ==> Preferences ==> C/C++ ==> Debug ==> Source Lookup Path
- I Add a Path Mapping: Project Source
- 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
- 我转到窗口 ==> 首选项 ==> C/C++ ==> 调试 ==> 源查找路径
- 我添加一个路径映射：项目源
- 在左侧我放置了 Cygwin 期望的路径，即 \home\MyName\projects，在右侧我放置了 Windows 路径，即 C:\cygwin\home\MyName\projects
Then when I debug it finds the source file fine.
然后当我调试它发现源文件很好。

Go to Windows->Preference->C/C++ -> Debug -> Source Lookup Path. Add following 'Path mapping'.
转至 Windows->Preference->C/C++ -> Debug -> Source Lookup Path。添加以下“路径映射”。
\cygdrive\c -> c:\

Although Above are given good answers but still it might not solve the problem sometimes phew!!!!
虽然上面给出了很好的答案，但有时它仍然可能无法解决问题，呸！！！！
Suppose you install Cygwin in C: but your eclipse workspace is in D: then there is a problem in your mounting
假设您在 C: 中安装 Cygwin，但您的 eclipse 工作区在 D: 中，那么您的安装就有问题
all you should do is, open the cygwing shell & type "mount" to get the following :
您应该做的就是打开 cygwing shell 并键入“mount”以获取以下内容：
Ritvika@Ashutosh ~
$ ls
Ritvika@Ashutosh ~
$ mount
C:/cygwin64/bin on /usr/bin type ntfs (binary,auto)
C:/cygwin64/lib on /usr/lib type ntfs (binary,auto)
C:/cygwin64 on / type ntfs (binary,auto)
C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto)
D: on /cygdrive/d type ntfs (binary,posix=0,user,noumount,auto)
Ritvika@Ashutosh ~
$
here my Projects are all under D:\ECWorkSpace, so my mapping needs to be present in Eclipse as: /cygdrive/d d:/
这里我的项目都在 D:\ECWorkSpace 下，所以我的映射需要在 Eclipse 中显示为：/cygdrive/dd:/
Hence, now Armed with this knowledge do what PathM says
因此，现在有了这些知识，就按照 PathM 所说的去做
1. goto Window ==> Preferences ==> C/C++ ==> Debug ==> Source Lookup Path
2. Add a Path Mapping: Project Source
3. On the left side put "cygdrive\d", & on the right put : "D:\"
This should work. ( It did for me :) ) You can Check this FAQ as well : https://wiki.eclipse.org/CDT/User/FAQ#I.27m_using_cygwin_and_when_launching_the_debugger.2C_it_complains_that_it_can.27t_find_the_source_file
这应该有效。（它对我有用:)）您也可以查看此常见问题解答：https: //wiki.eclipse.org/CDT/User/FAQ#I.27m_using_cygwin_and_when_launching_the_debugger.2C_it_complains_that_it_can.27t_find_the_source_file

I use MinGW + CDT, and it is giving me great satisfaction. I installed it many times and never had any disagreement. No much to configure than what you did with cygwin. Download the Eclipse for C/C++ developers (probably what you did) to get CDT(MinGW Tool Chain -> gdb + gcc) directly operational. Set your \\MinGW\bin\directory into your PATHand you should be good to go...
我使用MinGW + CDT，它让我非常满意。我安装了很多次，从未有过任何分歧。没有比你用 cygwin 所做的更多配置。为 C/C++ 开发人员下载 Eclipse（可能是你所做的）以CDT直接运行（MinGW Tool Chain -> gdb + gcc）。将您的\\MinGW\bin\目录设置为您的目录PATH，您应该很高兴...
Note : Like Cygwin, MinGW provides a Linux-like Shell.
注意：与 Cygwin 一样，MinGW 提供了类似 Linux 的 Shell。
For MinGW-64, ready-made builds are a little bit more difficult to locate. See here.
对于 MinGW-64，现成的构建更难定位。见这里。

Look at set-up of "Common Source Lookup Path" here: http://wyding.blogspot.dk/2009/04/setup-cygwin-toolchain-in-eclipse-cdt.html
在此处查看“通用源查找路径”的设置：http: //wyding.blogspot.dk/2009/04/setup-cygwin-toolchain-in-eclipse-cdt.html
