About NS2 Compilation Errors

I am using ns2 (ns-2.34) in ubuntu 16.04.
After executing the command to recompile NS2, the following error appears in make:
I don't understand what's leading to the error.
I'm sorry, but could you teach me?

Recompile Procedure

./configure        
 make clean     
 make depend        
 make ← error        
 sudo make install

The sample Makefile says the following, but

TCLSH=/usr/local/bin/tclsh 8.4
TCL2C=/usr/local/bin/tcl2c++

As a result of checking the dpkg command in your environment, you can see that the installed file is in /usr/bin/tclsh8.4, so you need to modify the Makefile description to suit your environment.
(tcl2c++ is written appropriately, but please check the actual environment and correct it.)

TCLSH=/usr/bin/tclsh 8.4
TCL2C=/usr/bin/tcl2c++

As I mentioned briefly in the comments section, /usr/local/bin usually includes compiled items from the source code.On the other hand, the distribution-provided packages will be installed in /usr/bin/ and so on.

An error occurred while attempting to create gen/ns_tcl.cc by redirect using the script in tcl 8.4.

An excerpt from Makefile of ns-2.34 as a reference.


TCLSH=/usr/local/bin/tclsh 8.4
TCL2C=/usr/local/bin/tcl2c++

$(GEN_DIR)ns_tcl.cc:$(NS_TCL_LIB)
    $(TCLSH)bin/tcl-expand.tcl tcl/lib/ns-lib.tcl$(NS_TCL_LIB_STL)|$(TCL2C)et_ns_lib>$@

You need tcl 8.4 (such as /usr/bin/tclsh or /usr/local/bin/tclsh 8.4) to compile, so why don't you reconfigure it by deploying a tcl package?
