Confirmed - I can reproduce this. I had a look at the cygwin host MIB implementation and it looks like that code is broken since a very long time. I'm not sure it has ever worked - at least one variable declaration is missing e.g.
If you want host MIB support on Windows I see two possible options:
- Porting the recently posted native Win32 implementation from MSVC to gcc (http://sourceforge.net/tracker/index.php?func=detail&aid=3129942&group_id=12694&atid=312694). This would involve adding the libraries indicated with "pragma comment" to the linker path in the configure script if the host MIB is enabled on Cygwin.
- Building the Net-SNMP source tree via MinGW with winExtDLL support enabled and hence using the Microsoft implementation of the host MIB via winExtDLL (at least in theory winExtDLL should work on Cygwin too, but I haven't got that working yet).
Any preference ?
Closing this bug report since the above question has not been answered.
