For example, every importation / definition will be reported unused, if it is not used by the semantic analyzer. This sadly does not mean that they are actually not used, but on the contrary it means that every importation / definition not marked is sure to be used.However this also means that if there are any unused importations / definitions in the project they will be contained in this list, thus considerably reducing every effort needed to find them.

==== Creating Symbolic Links
=== Creating Symbolic Links
By default, the first step of the build process is creating or updating symbolic links in the working directory of the project. The working directory contains symbolic links pointing to every file included in the project (this is not true for files contained in a central storage directory, because they are handled differently).

Everyone is allowed to write his own `Makefile`; however, the `Makefile` skeleton generated by the compiler always serves as a good starting point.

In this step C++ files are generated from virgin TTCN-3 and ASN.1 files. When a C++ file already exists, then the timestamp of the Compile file is used to decide whether a C++ file in question is uptodate or not.

==== Creating Dependencies
=== Creating Dependencies
Once the symbolic links have been created and the `Makefile` of the project has been properly edited if necessary, the command make dep has to be issued to find the dependencies between the resulting C++ codes. It is extremely important that the dependencies are always uptodate. If, for example, a TTCN–3 module is removed from the project, the dependencies between the C++ files must be updated, otherwise the command `make` fails.

Alternatively, incremental generation of dependency information is available when using Makefiles written for GNU `make`. Instead of modifying the `Makefile`, dependency information is written into separate files with `.d` extension (one for each `.cc` file). These files are included into the main `Makefile`. This has the advantage that the `Makefile` is not modified every time a dependency changes. Another benefit is that the dependencies are always updated during `make`; there is no need to explicitly run `make dep`. For information on how to set this option please refer <<4-managing_projects.adoc#the-makefile-creation-attributes-tab, here>>.

In the final step of the project building procedure a conventional C++ compiler is used to compile Test port codes and the generated C++ source code to a binary object code.
