Trying to compile on cygwin and get "undefined reference errors"

[wzapar00]

Can someone please help me out. I am trying to compile on cygwin and I keep getting the following errors.

As I mentioned before, Windows is not tested. I do not own a windows machine to be able to troubleshoot this.

This seems related to how gcc links. Suggestions are an addition to configure.in with the following gcc flag added "-fno-stack-protector" \" to disable these warnings which crash the compiler. Again this is Redhat Cygwin and should build just like Redhat. I have never had problems building anything with gcc on Cygwin, including net-snmp. Thanks again.

[wzapar00]

One other thing too. configure.in is no longer supported. It should be renamed configure.ac.

[AdrianSimionov]

Can you please confirm that adding this flag resolves the issue? For configure.in I will open a new bug, let's try to stay organized.

@wzapar00 how did you fix this? The flag u mentioned did not work for me, still get undefined reference

[KvalheimRacing]

Lol, I figured it out, I was not including all the .cpp files I used when I was compiling. So 100% user fault haha
