How to get gdb working with Eclipse CDT under windows (fails to find source code)

Question

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.

Answer 1

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.
