Hello guys... I am totally new to TTCN3. I have a problem related TTCN3. I have a project with different folders containing TTCN3 files and the ttcn modules have the import statement to access its variables from different directory. But while compiling through command line it gives me an error stating that there is no module with the identifier __.ttcn . Can anyone guide me where i am going wrong?

Hi Avdoot,

Welcome to TTCN-3 and Titan.


the compiler has to see all .ttcn (and .asn, .cc, .hh -if any), files to be able to compile. simplest way to solve this is to create a shell script that will
symlink all used files:

create a directory say bin (as in for binaries) which will be used to compile:

mkdir bin
cd bin


create and save a file say createlink.sh

with the following content:

#!/bin/sh 

ln -s /path/to/the/first/file/file1.ttcn           .
ln -s /path/to/the/second/file/file2.ttcn      .
ln -s /path/to/the/third/file/file3.cc
:
:


chmod + x createlinks.sh
./createlinks.sh


this will symlink all used files into the bin directory


now you can run make (assuming you already have a generated Makefile)


I hope this helps

Best regards

Elemer

You can use ttcn3_makefilegen to skip generating symlinks.
For example, assuming the following directory structure with 3 modules, where m imports contents of both m1 and m2:

./m.ttcn
./d1/m1.ttcn
./d2/m2.ttcn

Say you would like to build in ./tmp then cd to ./tmp and run the makefile generator with:

ttcn3_makefilegen -s ../m.ttcn ../d1/m1.ttcn ../d2/m2.ttcn

You can build in ./tmp by running make!

I also recommend to study the TITAN User Guide s3.2 for a better understanding of TITAN build mechanism!

hello Elemer Lelik,
I didn't create the makefiles in the directories because the makefile you generate only once. I thought the compiling of the ttcn file should be done before the Makefile Generation. Because the Makefile contains references to all the ttcn modules and .cc and .hh files. Am i wrong?
Should i generate the makefiles and then compile?

With Regards,
Avdoot

Hi Avdoot,

after you have created the symlink as above , you have to generate the Makefile with:

makefilegen -f *.ttcn *.cc *.hh     


or
 makefilegen -f file1.ttcn...filen.ttcn  file1.cc...filen.cc file1.hh..filen.hh


(makefilegen followed by the list of files you want to compile; -f will cause any previous files to be overwritten)


This will generate a Makefile in the bin directory

only after this you can start compilation with make.

Distributed Makefile is a bit more complicated , let's avoid that for the moment.
You need one central Makefile, in a directory where all files needed are either present or symlinked.

I suggest you look at the earlier posts where we published example projects with the description of the workflow.


Best regards
Elemer

Hi Elemer Lelik,
Thanks for your input.Now, I got to know a lot about the workflow of TItan. Before generating the makefile i need to generate the source and header files which i am not able to generate because of import statement. So where can i get to know more information about which ttcn files to generate, etc,

Hi Avdoot,

great ;
both the language and the tool have their learning curve, but past that you'll find out that is enormously efficient in network stuff.

hi Elemer Lelik,
After running make i got the following error.
Can you tell me the reason or source of following error?

I assumed it might be because of dependency and i tried by running the command makedepend but it gave me an error.
Where I am going wrong?

Hi Avdoot,

can you please pack your source files/directories, including your Makefile, scripts etc. into a compressed file and upload it here so we can take a look?

Hi Avdoot,

please find attached a compressed archive with your corrected project.

The biggest problem was that you have started from one of the published projects and arbitrarily removed files, especially C/C++ files.

Both test ports and protocol modules may consist of several files, that can contain TTCN-3 or C/C++ source code. For test ports , these constitute the test port body itself; for protocol modules, these might contain the encoding/decoding functions.


After unpacking the file, please do

cd ~/bin
../src/createlink.sh
make


The files should compile and create an executable named CoAP.

This can be run with

ttcn3_start ./CoAP coap.cfg


Mind you I have not checked whether it executes correctly.
Please also check the small changes I have made ; they are a prerequisite to successful compilation.


Also, please download the CoAP conformance test in github/titan.misc and compile/execute it for reference.



Best regards
Elemer

Hi Elemer Lelik,
I actually wanted to build a project with CoAP protocol and IPL4asp ports. So, I started from scratch. And regarding the c/c++ files, with my little knowledge about ttcn3, i assumed that the compiler will generate all the source and header files. Am i wrong with my assumptions?

Thank You for your input! i really learned a lot from it.

Avdoot Chalke

Hi Avdoot,

the compiler will generate source/header files from TTCN-3 and ASN.1 files, but there are some C/C++ files that have be added separately: some codecs, test ports, external functions etc.

Elemer
