ROTFL

Hmmmm. The cygwin package comes with SSL libraries, so I would *hope* that they are the same version. However, one possibility is that the libraries are not being pulled from the current directory but somewher else.

I've run into a few problems where I found the exact same stack trace in Google, which led to the solution. I was hoping that someone had seen this exact same problem before.

I am having a problem with the Cygwin gcc. I cannot figure out how to specify the path to OpenSSL installation directory (c:\OpenSSL), each time it gets to check_http.c it barfs saying it cannot find certain includes. Any tips?
