ns-allinone-2.31 make: *** [tools/random.o] Error 127

Hello,
this is my first question on this forum,hope to get a satisfactory answer.

i have ubuntu 9.10 installed on my laptop with ns-allinone-2.31.
i want to add a new module to NS2. i edited Makefile.in under
/home/ns-allinone-2.31/ns-2.31 directory. whenever i enter command
make -f Makefile.in
i get
make: *** [tools/random.o] Error 127
error.
i have gcc version 4.4.1.

i think some bug in ns-allinone-2.31 or some thing?

thanks

Welcome to LQ. .. ..

The usual approach would be, I think : cp Makefile Makefile-backup
&& cp Makefile.in Makefile.in-backup.
Then edit Makefile.in to include the new object, and run configure
to have a new Makefile created. ( And then run 'make'.)
.. Or you can edit the Makefile itself.
Running make -f Makefile.in is quite unusual.
Makefile and Makefile.in are not identical.
( 'diff Makefile.in Makefile' will show.)

It can of course be an error in your code.
Don't know, what "error 127" means.

thanks for reply.
there is no "Makefile" in ns2-31 ,just Makefile.in and makefile.vc.

i edited Makefile.in and added my own project.
when i run command
make
with no arguments it says
make: **** NO targets specified,
thats why i run
make -f Makefile.in
and it gives me error
make: *** [tools/random.o] Error 127

i havent done any thing to built in NS2 classes.
i dont know where is the problem.

Makefle.in is used by 'configure' to create a Makefile.
Makefile.in cannot be used by 'make'.

Just run ./configure to get a Makefile created.
But the correct / best way to do it is :
cd ns-allinone-2.31/ && ./install
Then you are sure, that the four dependencies tcl, tk, otcl, tclcl
are created. ( And can be used, when you compile ns.)

I.e first run install, then :
cd ns-allinone-2.31/ && mv ns ns-backup
And now you can add your own code, and edit Makefile.in + run ./configure.
Or alternatively edit Makefile, and run make.
