ttcn3_makefilegen with TPD files for hello world project [message #1848046]

Dear community,

I was able to compile and run the hello_world project (https://gitlab.eclipse.org/eclipse/titan/titan.core/-/tree/master/hello) with installed version of titan. For that I used the following command:

 ttcn3_makefilegen -l -f *.ttcn *.c* -e myExample  && make

For the reasons of not having all compiled cc and binary files in the same folder as the source, I thought about using a tpd file for generating the makefile which allows to push all generated files go to bin/. The current folder structure looks like that:

├── hello_world.tpd
├── MyExample2.cfg
├── MyExample.cfg
├── README.md
└── src
    ├── hello_world.ttcn
    ├── MyExample.ttcn
    ├── PCOType.cc
    └── PCOType.hh

The current tpd file looks like the following:

<?xml version="1.0" encoding="UTF-8"?>
<TITAN_Project_File_Information version="1.0">
  <ProjectName>Hello_world</ProjectName>
  <Folders>
    <FolderResource projectRelativePath="src" relativeURI="src"/>
  </Folders>
  <Files>
    <FileResource projectRelativePath="src/PCOType.cc" relativeURI="src/PCOType.cc"/>
    <FileResource projectRelativePath="src/PCOType.hh" relativeURI="src/PCOType.hh"/>
    <FileResource projectRelativePath="src/hello_world.ttcn" relativeURI="src/hello_world.ttcn"/>
    <FileResource projectRelativePath="src/MyExample.ttcn" relativeURI="src/MyExample.ttcn"/>
  </Files>
  <ActiveConfiguration>Default</ActiveConfiguration>
  <Configurations>
    <Configuration name="Default">
      <ProjectProperties>
        <MakefileSettings>
          <generateInternalMakefile>true</generateInternalMakefile>
          <GNUMake>true</GNUMake>
          <incrementalDependencyRefresh>true</incrementalDependencyRefresh>
          <targetExecutable>bin/MyExample</targetExecutable>
        </MakefileSettings>
        <LocalBuildSettings>
          <workingDirectory>bin</workingDirectory>
        </LocalBuildSettings>
      </ProjectProperties>
    </Configuration>
  </Configurations>
</TITAN_Project_File_Information>

However, when I generate the makefile with

ttcn3_makefilegen -f -l -d -t hello_world.tpd

I'm not successful as ttcn3_makefilegen does not find the ttcn models in the tpd files. See the following output:

ttcn3_makefilegen -f -l -d -t hello_world.tpd 
TPD file `hello_world.tpd' validated successfully with schema file `/usr/local/TTCNv3/etc/xsd/TPD.xsd'

Question/ Issue: How do I flag the ttcn modules correctly in the tpd file? Is there any other good way to avoid generating cc and binaries to the same folder than the source, particularity when projects grow?

Thanks for your help,
David

Your folder structure and tpd files looks OK and should work.

I tried to reproduce the issue, but it works for me:

ttcn3_makefilegen -f -l -d -t hello_world.tpd

Dear Gábor Szalai,

thank you for your reply. After checking your project which did also not work out, I have updated my titan version. Arg. Now everything works as expected.

Thank you,
David

Hi David,

Additionally, you can use relative paths to your sources in the ttcn3_makefilegen command, so you can separate your src and working (bin) directories. Just execute it in your bin dir.

Besides, if you would like to develop TTCN-3 code and you are able to work on GUI, I encourage you to use the Eclipse plugins of Titan, as it provides full syntax and semantic checks, as well as a transparent build flow that could simplify working with the compiler.
