Description Steven Tasker 2005-05-27 07:29:56 UTC
when emerging dsniff-2.3-r4 I get the following error:

gcc  -o dnsspoof dnsspoof.o pcaputil.o -lnsl -lrpcsvc  -L. -lmissing -L/usr/lib
-lpcap -L/usr/lib -lnet-1.0
dnsspoof.o: In function `dns_spoof':
dnsspoof.c:(.text+0x5ab): undefined reference to `__dn_expand'
dnsspoof.c:(.text+0x708): undefined reference to `__dn_comp'
collect2: ld returned 1 exit status
make: *** [dnsspoof] Error 1

If you run 

gcc  -o dnsspoof dnsspoof.o pcaputil.o -lnsl -lrpcsvc  -L. -lmissing -L/usr/lib
-lpcap -L/usr/lib -lnet-1.0 -lresolv

the command will work just fine and you can manually make and make install the
rest. this should be placed in the ebuild.

Reproducible: Always
Steps to Reproduce:
1. emerge dsniff

I can confirm.

In -r5, along with ~amd64 keyword. Thanks for reporting.

You shouldn't use append-ldflag for libs (it will not works with --as-needed for examples).
I attached a patch to fix to use -lresolv only when we need it
