A resposta é: ./configure --with-tcl-ver=8.5
Eu uso o Ubuntu 14.04 e estou tentando integrar o Evalvid 2.7 e o Ns2.35. Eu adicionei arquivos necessários como: myevalvid.cc, myudp.cc, myudp.h, myevalvid_sink.cc, myevalvid_sink.h. E dentro do Makefile.in eu coloquei myevalvid / myudp.o, myevalvid / myevalvid_sink.o e myevalvid / myevalvid.o na lista OBJ_CC.
Mas o problema é que, quando eu entro no comando ./configure, eu recebo esse erro do console referente ao programa tcl:

configure: error: Installation of tcl seems incomplete or can't be found automatically.
Please correct the problem by telling configure where tcl is
using the argument --with-tcl=/path/to/package
(perhaps after installing it),
or the package is not required, disable it with --with-tcl=no.
Alguém pode me ajudar a consertar isso, por favor. Eu realmente preciso fazer isso funcionar, continuar com o projeto em que estou trabalhando.
