Problems compiling pshtoolkit

Question

I have downloaded the pass the hash toolkit source codes from here. When I am compiling it with Visual Studio Ultimate 2010, I would get the following error:

findfuncs_msv10.obj : error LNK2019: unresolved external symbol _GetModuleInformation@16 referenced in function _FindMSV10Functions
whosthere-alt.obj : error LNK2019: unresolved external symbol _LsaFreeReturnBuffer@4 referenced in function _GetLogonSessionData
whosthere-alt.obj : error LNK2019: unresolved external symbol _LsaGetlogonSessionData@8 referenced in function _GetLogonSessionData
whosthere-alt.obj : error LNK2019: unresolved external symbol _LsaEnumerateLogonSession@8 referenced in function _main

How do I solve this error or is there another better way to compile the code. I'm new to C and I'm open to any suggestions.

Update: I have linked the Secur32.lib and the Psapi.lib and it compiles. Thanks alot

Answer 1

It sounds like you need to link to some additional libraries.

If you search for the functions listed in the errors (minus the leading underscore) in MSDN, it'll show you which libraries to link to.

e.g.

• GetModuleInformation is in either Kernel32.lib or Psaip.lib, depending on the version of Windows you're using
• LsaGetLogonSessionData is in Secur32.lib

Answer 2

You need to add the *.lib files to the Visual Studio project.
