Public bug reported:
Binary package hint: lprng
On Ubuntu Natty, the lprng source package fails to build with the
following error:
gcc -g -O2 -Wl,-Bsymbolic-functions -o lpr lpr.o openprinter.o stty.o child.o
copyright.o debug.o errormsg.o fileopen.o gethostinfo.o getopt.o getprinter.o

-lcom_err
/usr/bin/ld: krb5_auth.o: undefined reference to symbol
'krb5_encrypt_size@@k5crypto_3_MIT'
/usr/bin/ld: note: 'krb5_encrypt_size@@k5crypto_3_MIT' is defined in DSO
/usr/lib/libk5crypto.so.3 so try adding it to the linker command line
/usr/lib/libk5crypto.so.3: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[3]: *** [lpr] Error 1
As indicated by the error, the issue is that -lk5crypto is not being
passed. It turns out that configure.ac isn't using krb5-config, which is
the standard way to figure out what the linker flags should be. This
seems to have been fine in previous releases (and this version of the
package was never rebuilt since being imported from Debian), but Natty's
toolchain is not happy with this.
I'm attaching a debdiff that adds a few lines to configure.ac to try
krb5-config first before trying its built-in guesses at what the
Kerberos libraries are. Because this requires rerunning autoconf, the
debdiff also uses dh_autoreconf to do so.
