Checking the ./configure failure in config.log, we see that it creates a small program conftest.cpp:

extern "C" {
#include <com_err.h>
 
int main(void) {
  error_message(0);
}
}

      

... and it fails to compile with the command g++ -o conftest -g -O2 conftest.cpp -lkrb5.

But the following does work:

, the solution being that conftest should've been linked against libcomerr. That can be fixed by patching configure.in with this patch:

After that, ./configure runs, but make still fails with undefined references. That is because the link order is wrong in Makefile.in, which can be fixed with the following patch:

With the build phase thus fixed, a rather standard debian/rules can be used^[4]:

... and the package will build.

The package is now free of Lintian errors, and it will mount an NFS3 share from a Windows 2008 R2 server with Kerberos authentication.
