The CDT looks for Cygwin in the registry. But Cygwin 1.7 doesn't use the
registry anymore. It works if you upgrade from 1.5 to 1.7 but not if you
install 1.7 from a clean Windows or in another location.

Here is a blog post about what registry key to modify/create.

win-17.html

---------------------------

For posterity, here's the list of keys from the relevant Eclipse bug at
https://bugs.eclipse.org/bugs/show_bug.cgi?id=3D303900 :

[HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions]
[HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin]
[HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2]
[HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2\/]
"native"=3D"C:\\cygwin"
[HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2\/etc]
"native"=3D"C:\\cygwin\\etc"
[HKEY_LOCAL_MACHINE\SOFTWARE\Cygnus Solutions\Cygwin\mounts v2\/usr/bin]
"native"=3D"C:\\cygwin\\bin"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cygnus Solutions]
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cygnus Solutions\Cygwin]
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cygnus Solutions\Cygwin\mounts
v2]
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cygnus Solutions\Cygwin\mounts
v2\/]
"native"=3D"C:\\cygwin"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cygnus Solutions\Cygwin\mounts
v2\/etc]
"native"=3D"C:\\cygwin\\etc"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Cygnus Solutions\Cygwin\mounts
v2\/usr/bin]
"native"=3D"C:\\cygwin\\bin"

According to that bug, it'll be fixed in CDT 7.0, available in June.
